Read More Introduction Japanese barberry (Berberis thunbergii) is a perennial and woody shrub that grows in different regions of Iran and the world. The Berberidaceae family has a high potential in food and pharmaceutical industries due to its antioxidant, antimicrobial and anticancer activities. Elicitors are biotic or abiotic stimulators can induce responses in plants. Abiotic elicitors are used to increase secondary metabolites in plants. Nanoparticles have minimum dimensions between one and 100 nanometers, which have specific physical and chemical properties. Like many nanoparticles, zinc oxide and cerium dioxide nanoparticles are toxic to living organisms. The mechanism of toxicity of nanoparticles is generally caused by the induction of oxidative stress caused by the formation of free radicals. Nanoparticles of zinc oxide and cerium dioxide can increase the antioxidant capacity of plants by stimulating oxidative stress. Material and methods In order to study the changes in the physiological and biochemical characteristics of Japanese barberry under the influence of abiotic elicitors, an experiment was conducted in the form of a completely randomized design in the greenhouse and laboratory of the Faculty of Agriculture and Natural Resources of Imam Khomeini International University in 2019. Treatments including zinc oxide elicitors (0.1 g/L) and cerium dioxide nanoparticles (0.0002 g/L) and control (no elicitor) were investigated in three replicates. In this research, the amounts of protein, antioxidant enzymes and photosynthetic pigments in tissues of Japanese barberry were extracted and measured. Data analysis was done with SAS 9.1.3 statistical software. Comparison of means was done with Duncan's multiple range test and graphs were drawn using Excel software. Results and Discussion The results of the data analysis of variance showed that the effect of treatment with cerium dioxide and zinc oxide nanoparticle elicitors on the amount of leaf protein, antioxidant activity and also the amount of photosynthetic pigments was significant. Comparison of the means showed that these two elicitors increased the leaf protein content by 26.2% and 12.4%, respectively, compared to the control, but they did not have a significant effect on the root protein content. Cerium dioxide decreased the activity of guaiacol peroxidase enzyme by 77.1% in the root; But in leaves, the activity of this enzyme increased by 134.8% due to treatment with zinc oxide. The highest activity of leaf superoxide dismutase enzyme (25.2% increase compared to control) was related to zinc oxide treatment. The lowest content of catalase enzyme in leaves and roots was obtained with cerium dioxide and zinc oxide. Zinc oxide increased the activity of leaf ascorbate peroxidase enzyme by 111.8%; In the root, the highest and lowest activity levels of this enzyme were obtained from the control and cerium dioxide treatments, respectively. Both elicitors significantly increased the leaf peroxidase enzyme activity compared to the control (128.6% and 157.1%, respectively); However, only the treatment with zinc oxide caused a significant increase of 25.5% in the activity of this enzyme in the root. The highest activity of glutathione reductase enzyme in leaf and root was observed in zinc oxide treatment (23.3% and 12.5% increase compared to control). Nano zinc oxide increased the amount of total chlorophyll and carotenoid in the leaves compared to the control by 93.4 and 67.5%, respectively. Conclusion It was concluded that zinc oxide nanoparticles elicitor had the greatest effect in increasing the amount of photosynthetic pigments and enzyme activity. By using this elicitor in Japanese barberry culture, the amount of antioxidant enzymes can be increased and the extract can be used as a strong antioxidant in pharmaceutical products.

Read More IntroductionTomato is an economical high value product which is used fresh or processed. Having compound such as fibers, vitamin A, vitamin B, lycopene, carotenoids, ascorbic acid and polyphenols in this product leads to prevent the cancer and cardiovascular diseases. Even though biosynthesis and accumulation of this biochemical matter in tomato fruit when growing is affected by the production conditions such as methods of production environmental factors and plant genetics. Tomatoes produced in a closed hydroponic system have better flavor and marketability. This research is done to show the affects to the physical and chemical characteristics and productivity of two greenhouse tomato cultivars in two open and closed systems. Materials and MethodsIn this research the effects of two open (drip) and closed (modified nutrient film technique) hydroponic systems on physical and chemical characteristics and productivity of two greenhouse tomato cultivars (V4-22 cultivar breaded in Shahid Chamran University of Ahvaz and Amira cultivar from Rijkzwaan company of Netherland) was studied as split plot based on a randomized complete block design with three replications in agricultural faculty of Shahid Chamran University of Ahvaz. The information gathered and correlation between characteristics were analyzed statically by MSTAT-C 1.2 software. To compare the means, Duncan's multi domain test in 5% level was used. Some of the quantitative and qualitative characteristics include productivity, fruit length, fruit diameter and fruit volume, fruit firmness, pH, titratable acidity, total soluble solid, fruit dry matter, lycopene, fruit carotenoids, antioxidant capacity, polyphenols content, concentration of fruit elements such as potassium, sodium, calcium and magnesium were analyzed. Results and DiscussionThe results of the experiment showed that the most fruit length, fruit firmness, and calcium concentration were recorded in the plants cultivated in open system and the highest total soluble solid, lycopene, carotenoids and fruit sodium concentration were seen in the closed system. The most antioxidant capacity, polyphenols content, concentration of calcium and sodium were observed in Amira cultivar and the most titratable acidity was recognized in V4-22 cultivar. The maximum yield belonged to V4-22 cultivar (3847/29 g per plant) and minimum yield belonged to Amira cultivar (3648/70 g per plant). The interaction effect of hydroponic system and cultivar on concentration of magnesium and potassium in 1% level and dry matter in 5% level were significantly different. The correlation between Antioxidant capacity, fruit total soluble solids content, vitamin C, lycopene and polyphenols content with potassium concentration was positive and significant. ConclusionThe results showed that V4-22 cultivar had higher yield than Amira cultivar and this is due to the adaptation of this cultivar to the environmental conditions of Ahvaz greenhouse. In this study, crop yield in both open and closed systems was not significantly different and the closed system increased the quality characteristics of fruit including total soluble solids, lycopene and carotenoids compared to the open system. This can be due to the most availability of nutrient solution in the closed system compared to the open system. The lowest capacity of antioxidant and total polyphenols were obtained in V4-22 cultivar. The decrease in production of these secondary metabolites indicates that this cultivar is more compatible with production conditions.

Read More Introduction Soybean seeds are sensitive to storage due to their high oil content and they aged quickly. Aging of seeds leads to a decrease in the percentage and speed of germination and ultimately to a decrease in seed yield. Although the aging rate can be reduced with proper storage methods, the application of some treatments on the aged seeds or spraying some substances on the plants obtained from these seeds can be effective in improving the seed yield. The use of anti-aging substances such as seaweed extract in plants can act as antioxidants and reduce the effects of aging. Materials and Methods In order to evaluate the phenological stages and yield of soybean, an experiment was carried out in the research farm of Shahrood University of Technology during 2019 and 2020 in three replications. The treatments include the initial seed quality in two levels (normal seeds and aged seeds) and seaweed extract (Ascophyllum nodosum) in four levels (control, priming, foliar spraying and combined application of priming and foliar spraying with a concentration of 0.3%). The experiment was carried out as a factorial in the form of a basic design of randomized complete blocks. Results and Discussion In this research, applying accelerated aging caused a significant increase in phenological traits in soybean plants. The use of seaweed extract as a priming and the combined use of priming and foliar spraying could increase the rate of occurrence of phenological traits to a significant level. The seed yield in plants obtained from aged seeds was 32.69% less than that of control plants. The use of seaweed extract as priming, foliar spraying and the combined use of priming and foliar spraying increase the seed yield by 43.54, 15.69 and 87.85 percent, respectively. Aging caused a significant decrease of 23.50 and 25.33 percent of final emergence percentage. Pretreatment of normal and aged seeds with seaweed extract in the first year increased this trait by 16.33 and 7.33% compared to the absence of seaweed extract. In the second year of the experiment, the application of seaweed extract resulted in a 12.67% increase in seedling growth under normal conditions, and an 8.33% increase was recorded with the application of seaweed extract under aging conditions. Conclusion In this study, the application of seaweed extract as seed priming better than foliar spraying. It is possible to recommend priming and the combination of priming and foliar spraying with seaweed extract to accelerate the occurrence of phenological traits in soybeans. The combined use of priming and foliar spraying of seaweed extract is recommended to improve the performance of soybeans in normal and aged conditions.

Read More AbstractBackground and ObjectivesPomegranate (Punica granatum L.) is one of the most important fruits grown on a commercial scale in Iran. It has gained popularity worldwide due to its high economic, nutraceutical, and therapeutic values. Chilling injury and weight loss are the most important limiting factors for pomegranate fruit storage. Application of an edible coating such as carnuba wax on the fruit surface imparts a glossy appearance and better color, reduces fruit weight loss, extends storage life, and prevents microbial spoilage, which is extremely important to perishable fruit. Edible coatings create a modiﬁed atmosphere around the fruit by providing a semipermeable barrier to water vapor and gases, and their use offers an effective alternative to ﬁlm packaging due to their environmentally friendly characteristic. Material and MethodsThe present study conducted a factorial design based on completely randomized design with four replications to evaluate the effect of carnuba wax on pomegranate fruit storage. The treatments included carnuba wax in three concentrations 0, 0.5%, and 1%, and storage time in 3 levels (0, 45, and 90 days). After immersion and drying, the fruits were packed in plastic baskets and kept in a cold room at 4 ± 1 °C with 85 ± 5% of relative humidity. In each sampling removal, quantitative and qualitative characteristics such as weight loss (%), electrolyte leakage (percentage), chilling index, tissue firmness, total acidity, pH, color indices (aril and skin), fruit flavor, anthocyanin, skin freshness, and overall fruit acceptance were examined. ResultsThe results showed that carnuba wax prevented weight loss until the end of the storage period (90 days) but controlled ion leakage until 45 days of storage. The skin firmness of fruits and arils was higher in carnuba than in control samples. Increasing the concentration of carnuba wax resulted in lowering vitamin C but did not affect the antioxidant capacity. According to the panelists', the flavor, skin freshness, and pomegranate fruits' appearance in both carnuba treatments were better than the control samples. DiscussionThe results of this study showed that carnuba-coated fruit has protective quantitative and qualitative characteristics during cold storage. Moreover, exogenous application of carnauba wax showed improvement in pomegranate storability at 4 °C, which otherwise leads to chilling injury and reduction in quality. The treatment with carnauba wax preserves fruit weight, total acidity, and skin freshness. Pomegranate carnuba-coated fruit exhibited a signiﬁcantly lower chilling rate as compared to the control samples. According to the results, carnuba 0.5% maintained most qualitative and quantitative properties of pomegranate fruit until 90 days at 4°C.

Read More Abstract Background and Objectives Plant cells often increase cold tolerance by reprogramming their genes expression, which results in adjusted metabolic alternations, a process enhanced under cold acclimation (CA). In this study, responses of Carbohydrate alteration and delta12 and delta15 genes expression to cold stress (CS) phases were comparatively studied in three genotypes of bread and durum wheat differing in sensitivity. Two of them (Norstar, bread wheat and Gerdish, durum wheat) were tolerant to CS and the other one, SRN (durum wheat) was sensitive to CS. Materials and Methods Seeds of Norstar (hexaploid, bread wheat) and the two genotypes of Gerdish and SRN (tetraploid, durum wheat) provided by Dryland Agriculture Research Institute (DARI) of Iran were soaked in distilled water and then germinated in Petri dishes on filter paper for 72 h at 25 C in a thermostat. Subsequently, the seedlings were planted in pots. The cooling regime adopted in our experiments allowed us to differentiate the examined genotypes in terms of their tolerance to CS. In our experiment, the plants were moved from control conditions immediately into the acclimated temperature of 4–5 ºC for 14 days with the same photoperiod and irradiance. Leaf samples of genotypes were harvested and analyzed after 14 days under these conditions. After 14 days of CA, the plants were placed into a climatic chamber chilled preliminary to 0 ºC. During further treatments, the temperature was lowered gradually to -5 C (at the rate of 0.5 ºC min-1 ), and the plants were incubated at this temperature for 12 and 24 h. Total cellular RNA was extracted by Biozol method (Fersion Pooyesh, Tehran, Iran) using 80 mg FM leaflets. Applying fermentase reverse transcriptase enzyme instruction, the first strand of cDNA was produced after DNase treatment. Primers were designed using primer 3 to obtain 18–21 bp length. Carbohydrate extraction and determining the carbohydrate concentration were done by 80% ethanol and the AOAC method, respectively. Results These responses confirmed the existence of a wide range of genetic capacity in durum wheat to increase cold tolerance particularly in Gerdish. The findings of the present study showed that under experimental treatments, the carbohydrate content significantly changed so that cold stress in acclimated plants increased sucrose, glucose and fructose contents particularly in Norstar and Gerdish as compared to the SRN plants. Increasing expression of delta12 and delta15 genes under cold stress in Norstar and SRN genotypes in comparison with SRN indicates the capacity of cells in increasing cold stress. Discussion The results may be a sign for associating other metabolite or enzyme activities to create relative tolerance against cold-induced oxidative stress. Also, these responses showed high genetic diversity for cold tolerance in durum. Eventually, assessing the dynamics of cell responses after CS without CA phases could profitably be a novel path in plant stress response investigations in the short run.

Read More Abstract Background and Objectives Organic fertilizers are carbon-based compounds that increase the productivity and growth quality of plants. Municipal waste compost is an organic manure that improves the physical, chemical and biological properties of soil and adds organic matter and exerts a positive effect on elements absorption, quality and yield of saffron. In addition, in saffron cultivation, it is possible to produce considerable amounts of stigma by using of standard mother corms with a minimum weight of 8 g. Therefore, the aim of this research was to investigate the interaction effects of municipal waste compost and mother corm size on chemical properties of saffron. Materials and methods This experiment was conducted with a factorial arrangement based on randomized complete block design with three replications at the Agricultural Research Station, University of Birjand during the growing season of 2014-2015. Treatments were four levels of municipal waste compost (0, 5, 10 and 20 t.ha-1) and three mother corm weights (0.1-4, 4.1-8 and 8.1-12 g). Flower of saffron was measured during autumn of 2015. Total phenol was determined using the Folin-Ciocalteu assay. Free radical scavenging activity of the samples was determined using DPPH method. Secondary metabolites of saffron (crocin, picrocrocin and safranal) were measured according to Iran’s national standard. Results The results showed that the highest total phenol and antioxidant activity (10.0789 mg.100 gr-1 and 65.66%, respectively) was obtained in treatment 20 t. ha-1 compost and the lowest (10.0785 mg.100 gr-1 and 62.58%) was recorded in control. Results showed that addition of the compost rate significantly increased secondary metabolites (crocin, picrocrocin and safranal). So, corm weight had a significant effect on antioxidant activity and the main secondary metabolites and the highest characteristics were obtained for corm with 8.1-12 g. As, the effect of interaction of municipal waste compost and corm weight significantly affected the main secondary metabolites. Discussion The results showed that fertilizer treatment and corm weight influenced chemical properties and the main second metabolites of saffron positively. It has been reported that plants cannot simultaneously allocate resources to growth and defence and that there is competition between proteins and phenolics in plants for the common precursors involved in their biosynthesis .These results led us to presume that saffron plants may utilise benefits from compost fertilizer for their protein synthesis and growth development. On the other hand, organic matter (e.g. compost) acts as precursors or activators of phytohormones and growth substances and secondary compounds in plants. The type of soil and the content of organic compounds in soil can have a decisive effect on increasing the content of organic compounds in soil and strengthening antioxidant activity.

Read More Background and Objectives Pomegranate is classified as a non-climacteric fruit, so it is considered as insensitive to ethylene. However, in some other non-climacteric fruit it has been shown that ethylene accelerates senescence or increase chilling injury symptoms during postharvest life. In this study, to determine the sensitiveness of pomegranate fruit to ethylene, the effects of ethylene and 1-MCP (as an ethylene inhibitor material) treatments were investigated on the pomegranate storability. Material and Methods Pomegranate fruit cv. ‘Malase Yousef Khani’ was harvested at the ripening stage (full aril coloring) from an orchard near Saveh city, and treated following treatments; 2 μL/L ethylene for 48 hours, 1 μL/L 1-MCP for 24 hours, and 2 μL/L 1-MCP for 24 hours as well as a combination of 2 μL/L 1-MCP and μL/L ethylene treatments. Fruit without any treatment was put as control. The treatments were applied inside the polyethylene container. Then the treated fruits were stored at 4°C and 90% RH for up to 3 month. The fruits were removed from storage in 1, 2 and 3 months of storage and after 3 days keeping at room temperature as shelf life was analyzed. The experiment was conducted as a factorial based on a completely randomized design with 3 replications at Shahed University in 2016. Results Results showed that ethylene treated fruits, as compared to 1-MCP treated fruit (even in presence of ethylene in combination treatment) had less fruit and aril marketability, as well as less firmness, ion leakage, total phenol content and antioxidant capacity, whilst this fruit had more weight loss than 1-MCP treated fruits. Ethylene treated fruit had also less fruit and aril marketability, and less antioxidant capacity than control fruit. The control fruit had less fruit and aril marketability, ion leakage, total phenol content and antioxidant capacity than 1-MCP fruits. Discussions According to these results, pomegranate fruit was sensitive to ethylene and its postharvest loss, such as chilling injury symptoms, electro leakage, and antioxidants reduction was accelerated by presence of ethylene around the fruit. On the other hand, since in the most measured characteristics, control fruit had a lower quality than 1-MCP treated fruit, it seems that pomegranate is very sensitive to ethylene and even low level of internal ethylene is enough to accelerate the postharvest loss of this fruit. Therefore, removal of ethylene from the pomegranate storage, or using the anti ethylene materials such as 1-MCP can be effective in increasing posthrevst life of pomegranate fruit.

Read More Background and Objectives Seed deterioration is a natural phenomenon that occurs in all seeds and leads to gradual decline of seed viability during storage. However, the rate of seeds age depends upon their physiological status, genetic constitution and storage conditions. The lipid peroxidation through the production of free radical plays an important role in the loss of seed viability during seed storage. Material and Methods In order to investigate the effect of deterioration on germination indices and enzymes activity of the flax oil seed, a factorial experiment was conducted based on a Completely Randomized Design with four replications in the seed laboratory of Yasouj University in 2015. The factors included 4 levels of temperature (15, 25, 35 and 45oC) and moisture content (5, 9, 13 and 17%). With relation intended seed moisture, Hampton and Teckrony (1995) was calculated. After determining the moisture content of the seeds in envelopes of aluminum foil was placed, then the amount of water the need added and to ensure that the packaging and moisture exchange with the outside world for 24 hours at 15 °C were identical to the seed moisture and then for 6 months in storage conditions at temperatures of 15, 25, 35 and 45oC were kept. Results Analysis of variance showed that the single effects including temperature and seed moisture content experimental treatments for traits including germination percentage, germination rate, seedling vigor index (weight), activity enzymes antioxidant catalase, superoxide dismutase and ascorbate peroxidase, soluble proteins, electrical conductivity and oil percentage were significant (P≤0.01). Also, the interaction temperature and seed moisture content of all treatments except for enzyme, activity of superoxide dismutase and ascorbate peroxidase were significant (P≤0.01) but were significant (P≤0.05) for the activity of superoxide dismutase and ascorbate peroxidase. The results showed that with increasing temperature and moisture content, all the physiological and biochemical traits, except for electrical conductivity, decreased. The decrease in germination was also associated with a decrease in the activity of antioxidant catalase, superoxide dismutase and ascorbate peroxidase and as a result the antioxidant system was not sufficient to protect seeds against free radical damage. With the increase in reactive oxygen species, lipids peroxidation increased, probably due to the destruction of cell membranes, increased electrical conductivity seed the negative correlation between the electrical conductivity and the activity of the enzymes antioxidant indicator of the issue. Discussions Thus, oil flax seed deterioration was closely related to decrease in the activities of free radical detoxifying enzymes and increased lipid peroxidation. In general, the best flax seed storage condition is at 15°C and 5 percent moisture content.
