Mandarin is considered as a sensitive fruit to low temperatures and its long term cold storage would result in some disorders such as pitting and reducing quality. This experiment was done to evaluate the effects of different intermittent warming (IW) treatments on quality and longevity of “Kinnow”. IW was applied at five levels (including transfer to higher temperature 24 h a week, 48h a week, 24 h in two weeks, 48 h in two weeks and control) on fruits and the quality of fruits was analyzed at three stages (i.e. 0, 45 and 90 days after cold storage). The results showed that with increasing the storage time, fruit weight loss increased significantly and IW led to more weight loss. Other quality parameters such as TSS and titratable acidity were not affected by IW but evolution of obtained data for chilling index, electrolyte and potassium leakage demonstrated that IW treatment reduced the chilling injury symptoms effectively. Among applied IW treatments in this study, the best results were obtained for fruits that were exposed to higher temperatures 24 h a week or two weeks.

In order to evaluate the effects of foliar application of potassium sulfate on some quantitative and qualitative characteristics of three olive (Olea europaea L.) cultivars, two split plot field experiments, arranged in complete block designs with three replications, were carried out through 2012–2013 in an orchard located in Ahvaz, Khuzestan province, Iran. Three olive cultivars (Mission, Coronaiki and Dezfuli) and three foliar applications of potassium sulfate (0, 1 and 2 g.L-1) were randomized in main plots and sub-plots respectively. The interaction effect between year and cultivar was significant for fruit fresh weight, dry weight of fruit pulp, stone weight , pulp: stone ratio, oil content (P≤0.01) and fresh weight of pulp (P≤0.05). Also, the interaction effect between year and foliar potassium application was significant for fruit fresh weight, dry and fresh weight of fruit pulp (P≤0.01) and stone weight (P≤0.05). The interaction between cultivar and foliar application of potassium sulfate for fruit fresh weight, dry and fresh weight of fruit pulp was significant at 1% probability level. In addition, interaction effect between year, cultivar and foliar application of potassium sulfate was significant for fruit fresh weight, dry and fresh weight of fruit pulp, oil content of the fruit pulp (% D.W.) at 1% probability level, and other traits at 5% probability level. Thus, it can be concluded that annual variability in the growth environment had an important effect on the parameters studied in this experiment. Dezfuli cultivar had more oil content than other cultivars that could be due to genetic diversity among cultivars for using sources in enhancement oil content and also more compatibility with the environmental conditions in this area. Foliar application of potassium sulfate increased unsaturated fatty acids and decreased saturated fatty acids in Dezfuli and Coronaiki cultivars. The highest content of oleic acid and oleic acid: linoleic acid ratio (60.54 % and 8.38) was found in Coronaiki cultivar with foliar potassium application (2 g.L-1) and the lowest amount in Dezfuli cultivar with control treatment (48.90 % and 1.67). Therefore, year conditions as well as foliar application of potassium sulfate can have a positive impact on ftuit weight, percentage of olive oil and fatty acid composition.

Arbuscular mycorrhizal fungi benefit from a symbiotic relationship with the plant, which is currently one of the strategies used to reduce stress. The experiment was factorial in a randomizing complete block with three replications. The first factor was three levels of drought stress including:D1 (%100), D2 (%80), D3 (%60) field capacity of soil moisture and the second factor included six level mycorrhizal: G1(Glomus mosseae), G2(Glomus intraradices), G3(Glomus fasiculatum), G4(mixture of three fungal species G1, G2, G3) in sterile soil, C1(Control 1 without fungus in sterile soil), C2(Contorl2, without fungus in non-sterile soil). The measured traits were fresh and dry weight of shoot, root colonization (%), electrolyte leakage (%), total chlorophyll content and proline accumulation. Results showed that the effect of drought stress on all traits was significant except for fresh weight and colonization of root lettuce (P<0.01). The lowest and highest fresh and dry weights of shoot were observed in D1 and D3 treatments, respectively. Application of mycorrhizal fungal inoculum on all traits was significant except for root fresh weight (P<0.01) and (P<0.05). Using G. mosseae was the most important effect in most of the growth characteristics. Interactions between mycorrhizal fungi and drought stress on contents of total chlorophyll and proline accumulation (P<0.01) were significant. The highest and lowest total chlorophyll contents obtained were at 60% moisture, respectively, in plants inoculated with mycorrhizal fungi (G. mosseae) and control plants (control 1). To increase the resistance of plants to drought stress a G. mosseae is recommended to be used.

Holy Basil is a perennial shrub plant that belongs to Lamiaceae family. Aerial parts of this plant have been used in food, pharmaceuticals, cosmetics and perfumery industries. Leaves of this plant contain 0.5-1.5% essential oil and main oil components are eugenol, methyl eugenol, carvacrol, estragol, and eucalyptol. In order to evaluate the effect of foliar application of zinc fertilizer on morphological traits of holy basil, an experiment was conducted in research farm of Department of Horticultural Science, Shahid Chamran University of Ahvaz based on randomized complete block design with six treatments and three replications. The treatments were nano zinc chelate (0, 0.5, 1 and 1.5 gr.lit-1) and zinc solfate (1 and 1.5 gr.lit-1) fertilizers. Foliar application of fertilizer was done at six or eight leaf stage and was repeated with an interval of 15 days until the end of the study. Morphological traits includingplant height, branches number, leaf number, leaf size (length and width), leaf area, stem diameter, main inflorescence length, inflorescence number, fresh and dry weights of leave, stem and aerial parts were measured at full bloom stage. The results showed that the effect of foliar application of zinc fertilizers on all measuredmorphological traits of holy basil was significant (p≥0.01). The highest and lowest values of mentioned traits were obtained in plant sprayed with 1.5 gr.lit-1 nano zinc chelate and control, respectively. Overall, given the non significant difference between 1 and 1.5 gr.lit-1 treatments, to increase morphological traits of holy basil, foliar application of nano zinc chelate with 1gr.lit-1 is recommended

Nowadays providing silver nano particles being done in various chemical ways, in which we face different major problems (e.g., instsbility of solution and the hi-tech equipments) is vitally needed. Thus, researchers have tried the green systems which have the least amount of bio dangers, and are easier to use. The silver nanoparticles were investigated by using green fruit extract of Melia azedarach. The effect of extract and silver nitrate concentration on amount of silver nanoparticles absorbance were evaluated as a factorial experiment based on a completely randomized design with three replications. X-ray diffraction was used to confirm the crystalline nature of the particles. Thesize and particles size distribution was assessed by Transmission electron microscope. Then antibacterial properties of synthesized nanoparticles were studied using the dick method. Nanoparticle synthesis relative monodisperse, hesagonal with an average size of 20 nm in Melia azedarach green fruit extract was reported. A according to the results, the interaction of silver nitrate and extract concentration was significant on amount of synthesis absorbance. The antibacterial activities of the synthesized nanoparticles were effective on Staphylococcusaureus and Pseudomonas aerauginos. Given that antibiotic resistance is a common problem to destroy the bacteria, nanomaterials as materials can be used for containment and eradication of these bacteria, but the resistance of clinical isolates in comparison with standard strains should be investigated.

Water deficit is one of the most important environmental factors that limit crop productivity. Therefore, the need for evaluation of crop tolerance to drought has become urgent. It has been reported that drought resistance of rootstocks is conferred to scions. This study evaluated the response of three apple rootstocks Gami Almasi, MM106 and MM111 to drought stress in in vitro conditions. This experiment was carried out as a factorial experiment based on completely randomized design (CRD) with three replications. Water stress induced by the incorporation of 0, 1, 2 and 4 % polyethylene glycol (PEG-6000) into the Murashige and Skoog medium was applied for 6 weeks. Results showed PEG-induced drought stress reduced growth parameters (length of shoot and root, fresh weight of shoot and root), chlorophyll index and promoted other biochemical parameters (content of proline and soluble sugar and protein and Catalase and Guaiacol peroxidase enzyme activity), but had no significant effect on the shoot diameter. The lowest length of shoot and root, fresh weight of shoot and root and chlorophyll index was observed for MM106 rootstock in 4% PEG treatment and the highest proline, soluble sugars and Catalase were in Gami Almasi rootstock in 4% PEG treatment. According to the results, the Gami Almasi is a resistant rootstock to drought stress.

Understanding of the mechanisms affecting root uptake, transport and grain deposition of cadmium can successfully improve the success of breeding programs aiming to produce low cadmium accumulating genotypes. To determine the role of potassium in cadmium uptake by roots, transport to shoot and accumulation in the grain of two durum wheat (Behrang and Yavarous), a pot experiment was carried out, using a factorial experiment based on randomized complete block design with three replications in different treatments: control, 20 mg Cd kg-1 soil (CdCl2), 20 mg Cd kg-1 soil with two levels of 300 and 450 mg K kg-1 soil as potassium sulphate, and two levels 30 and 45 mg K kg-1 soil as nano chelate potassium 27%. Cadmium decreased differentially the concentration of potassium in roots, leaves and grains in both cultivars, but cadmium concentrations were increased. The highest and lowest cadmium concentration was found in roots and grains, respectively. Potassium application in combination with cadmium through competition led to the decrease of cadmium concentrations compared to cadmium treatments in roots, leaves and grains of both cultivars, but increased potassium concentrations. According to the findings in this study, potassium plays an important role in grain quality improvement by increasing potassium concentrations and decreasing cadmium concentrations.

Abstract
Savory is one of the most important vegetables with high medicinal values whose growth is influenced by environmental factors including mineral nutrition. This study was done based on completely randomized design with 4 replications, under greenhouse conditions in order to evaluate the effect of organic and biological fertilizers on some morphologic and physiologic traits in savory during 2013. Treatments were control (without fertilizer application), NPK fertilizer, Vermicompost at 20 and 40 % of pot volume, manure at 20 and 40 % of pot volume, and phosphate biofertilizer (Barvar 2). The results showed that plant height, leaf area, number of leaves, fresh weight, stem diameter, P and N concentration in shoots were significantly influenced by treatments, but shoot dry weight and K concentration were not affected. The highest plant height, leaf number, leaf area, fresh and dry weight and N concentration were obtained in vermicompost 20% treatment. The highest stem diameter was in manure 20% treatment, while the highest chlorophyll index and P concentration were obtained in biophosphate and 20% vermicompost treatments.

All of established jujubes genotypes in Fadak Botanic Garden of Dezful belong to Ziziphus spp., and the Rhamnaceae family. Their species are Ziziphus spina-christi and Ziziphus mauritiana or hybrids between them, and they are considered as fruit trees. Because of the differences between fruit traits of mentioned genotypes, fruit and stone morphological traits were examined in this study. For this purpose, 14 morphological traits were measured in fruit and seed genotypes. Cluster analysis included genotypes in five clusters with 2 main genotypes of Ziziphus mauritiana situated in cluster III and 3 stoneless genotypes situated in cluster II. The results of fruit length, diameter, volume, and weight showed significant superiority in "Ghaffari" genotype with 39.4 mm, 23.9 mm, 10.977 cm3 and 11.817 g, respectively. In relation to fruit shape (fruit length /diameter ratio) and pulp percentage, "Bakhtiari" genotype showed significant superiority, with 1.806 and %95.92, respectively. Thus, significant superiority in mentioned traits, which show that the fruits are large, belonged to Z. mauritiana genotypes. Except for acidity that made "Arvand Hybrid" genotype superior, in other traits, significant superiority belonged to Z. spina-christi genotypes. However, some of hybrid genotypes showed superior quantitative and qualitative traits of parents by acceptable extent. Of course, some hybrid genotypes have inherited good qualitative and quantitative characteristics of both species parents, which can bring to them as fruit trees with good market.
