Read More AbstractIntroductionSummer savory (Satureja hortensis L.) belonging to the Lamiaceae family, is used as a spice and traditional herb in Iran. This plant has shown antispasmodic, antidiarrheal, antioxidant, sedative and antimicrobial activities. The basic requirement for plant breeding programs is a germplasm diversity that provides necessary facilities for breeding species with desirable features. Therefore, accurate identification of genotypes is considered as a prerequisite in this manner. Phenotypic characteristics are the first markers that have been used for diversity researches. Materials and MethodsIn this research, 20 accessions of S. hortensis were chosen from Iran, Bulgaria, Germany, Czech, Georgia, Syria, Hungary, Poland, Italy and Uzbekistan. Some morphological and phytochemical characteristics such as internode number, shoot number, number of days to germination, collar diameter, fresh weight of aerial part, bract fresh weight, flower number, peduncle length, 1000-seeds weight, flower fresh and dry weight and essential oil components were studied. The measurements began after the 50% of flowering stage. Results and DiscussionBased on the results of morphological studies, internode number (11.03), shoot number (18.58), 1000-seeds weight (925.97 mg) high variable Uzbekistan accessions were best in this traits. Maximum flower number (26.34) and flower fresh weight (26.14 mg) were obtained from Bulgaria accession. Essential oil amount was higher in Karaj accession. Correlation coefficients among traits showed that fresh weight of aerial part had the highest correlation with flower fresh weight (0.97). Cluster analysis based on Euclidean distance divided the accessions into four major groups in which the third and fourth groups had valuable characteristics. The Bulgaria accession had the highest ɣ-Terpinene and Borneol. The Karaj accession was the best in carvacrol and delta-3-carene content. Clustering from essential oil component assigned accessions into five clusters. It can be suggested that there is a considerable genetic variation among S. hortensis accessions. The main purpose of this study was to determine genetic diversity among S. hortensis accessions from Iran and other parts of the world. Significant differences were found among the accessions in almost every parameter measured. The range of vegetative and flower values obtained in this study was more than those reported in previous researches about S. hortensis. With increasing shoot and leaf number, Iran appears to be the main place to trap sunlight for photosynthesis and consequently provides the condition to produce flowers, seeds and secondary metabolites. Thus, Uzbekistan and Bulgaria accessions having high values of leaf and flower can also be considered for cultivation and breeding programs. ConclusionIn this study, agro-morphological and essential oil properties of S. hortensis accessions originated from Iran and some Asian and European countries were evaluated. The study revealed a high level of diversity in morphological and phytochemical traits among S. hortensis accessions. This needs a breeding approach during the domestication process to obtain homogenous cultivars with suitable agricultural properties. Keywords: Cluster analysis, Essential oil, Genetic diversity

Read More AbstractIntroductionNowdays, one of the major environmental stresses challenging agricultural produce worldwide, is progressive soil salinity. The majority of the soils in the arid and semi-arid regions face salinity. This is a huge threat for agricultural sustainablitty. With salinity adding-up, plants growth and development greatly decline due to reduced osmotic potential, unbalanced nutrients available and the variations in the type and content of growth regulators which negatively influence the plant yield and productivity. Under salinity situations, using micronutrients plays a vital role in the tolerance of plant against ROS molecules. These nutrients motivate antioxidant enzymes and hence, improve plant responses to the ROS molecules generation. As a result, they improve the yield, quality and productivity of plants under stressful conditions. Materials and MethodsAn experiment was conducted to study the effects of NaCl salinity stress (0, 50, 100 and 150 mM) and Foliar application of common and Nono-form Zinc-oxide (0, 5 and 10 mg L-1) on Rosmarinus officinalis as factorial based on RCBD with three replications at 2017- 2018. Results and DiscussionThe results revealed the interaction effects of salinity levels and Zinc Foliar application on chlorophyll b content, N, P, K, Na and Zn content, leave relative water content as well as essential oil yield. The highest data for chlorophyll b was recorded with no stress × 10 mgL-1 Nono-zinc spray. Relative water content for both Zn forms (0, 5 and 10 mgL-1) was maximum with no salinity treatments. The greatest data for essential oil yield was traced with NaCl0 × 10 mgL-1 Nano-zinc and NaCl0× 10 mgL-1 Zinc Oxide. NaCl0× 5 mgL-1 Nano-Zinc increased K+content in plant. For Zn compositional content, the highest data was recorded with no-salinity × 5 and 10 mgL-1of Nano-Zinc as well as with no-salinity × 10 mg L-1 of common zinc source. Aerial parts dry weight and Fe and Mg content were affected by independent effects of salinity and Foliar application of Zn. Aerial parts dry weight and Mg content increased at no salinity stress and 50 mM salinity. Chlorophyll a and Fe content were influenced by the non salinity levels. Foliar application with 0 and 10 mg L-1nano-Zn increased Mg content in plants. Salinity is one of the predominant stressors influencing the plants throughout all their life cycle. The results revealed that salinity drastically influenced rosemary dry weight, photosynthetic pigments content, as well as Mn, Cu, and Fe content. Zn Foliar application improved aerial parts fresh weight and the content of Mg, Cu, and Fe. In general, rosmary is salinity tolerant up to 50 mM without significant reduction in yield component. Therefore, the Foliar application of Nano-Zinc as Oxide form improved yield and growth characteristics. ConclusionSalinity drastically influenced the growth and physiological responses of the plants. Using Foliar treatments was able to partially ameliorate the salinity adverse effects and, promoted the growth and productivity of rosemary. However, economical administration of Foliar treatments needs more in-depth studies.

Read More Abstract Background and Objectives Any improvement in agricultural system that results in higher production should reduce the negative environmental impact of agriculture and enhance the sustainability of the system. Seaweed extracts (SWE) are known to cause many beneficial effects on plants as they contain growth promoting hormones, trace elements, vitamins and amino acids. Humic acid plays a vital role in soil fertility and its application increases the plant growth and nutrient uptake. The present study was undertaken to investigate the effect of SWE, humic acid and chemical fertilizers on the morphological and biochemical characteristics of Trigonella foenum-graecum L. Material and methods The experiment was carried out in 2016 at the Agricultural Research Greenhouse at Imam Khomeini International University, Qazvin, Iran. The experiment was based on a completely randomized design with four treatments including: SWE, humic acid, chemical fertilizers and control and 7 replications. The pots were filled with 5kg of farm soil, which was evenly mixed with recommended level of chemical fertilizers (N; 0.08, P; 0.06 and K; 0.1 g/kg soil) for chemical fertilizer treatment. Seeds were sown at a depth of 1.5 cm in each pot. Seedlings were thinned to five plants per pot 10 days after emergence. In 4 leaves, appearance stage, SWE and humic acid treatments were applied as a foliar spray every 14 days, for three times before harvesting. Growth parameters were measured in correct time. The biochemical constituent pigments such as chlorophylls and carotenoids and also total ascorbic acid in leaf were estimated in control and treated plants using standard methods. Dried seeds of Fenugreekwere subjected to hydro distillation for 3h using a Clevenger-type apparatus to produce oil and essential oil percentage was measured. Results In relation to the mean comparisons, the maximum shoot length and the highest number of pods per plant was obtained in plants receiving SWE and NPK. Maximum plant fresh and dry weights were observed in plants received SWE. All fertilizer treatments increased the number of seeds per pod but there were no significant differences between the treatments. The highest chlorophyll b, total chlorophyll contents, total carotenoids, ascorbic aicd and essential oil percent were obtained in plants that received SWE. Discussion Foliar application of seaweed extract fertilizer on fenugreek plants significantly increased all the examined growth parameters of the plants compared to the control. These results agree with previous studies where growth and plant vigor of dill, coriander and fenugreek plants were enhanced by seaweed extracted treatment. Seaweed extracts create equilibrium in growth as a result of the present auxins which will increase vitamins and hormones produced in the treated plants. Results showed that treatments had a significant effect on total chlorophyll, chlorophyll 'a' and 'b', total carotenoids and essential oil content of fenugreek. Seaweed extracts contain cytokinins as well which induce the physiological activities and increase the total chlorophyll, carotenoids and ascorbic acid in the plant.
