In order to investigate the effect of ellagic acid on the growth indices and leaf aging process in soybean, an experiment was conducted during the two years of 2018 and 2019 in the research farm of Shahrood University of Technology's Faculty of Agriculture. The experiment was carried out factorial in the form of a randomized complete block design in three replications. The experimental treatments include the initial seed quality at two levels (normal seeds and aged seeds) and the application of ellagic acid at four levels (control, priming, foliar spraying and combined application of priming and foliar spraying with a concentration of 50 mg/L). The results showed that accelerated aging decreased the amount of chlorophyll, carotenoid, plant height, leaf and stem dry weight, oil percentage and seed yield compared to the control. The use of ellagic acid in the form of priming, foliar spraying and their combination in this study increased the percentage of oil by 0.23, 0.24 and 0.29%, respectively, compared to the control. Priming, foliar spraying and the combined application of priming and foliar spraying with ellagic acid improved the grain yield by 23.59, 23.23 and 55.48%, respectively. The use of ellagic acid as seed priming and foliar spraying better than other levels. Finally, it is recommended to use this material as a priming to increase the percentage of oil and yield of soybean.

To determine the effects of priming and planting density on improvement of morphological and physiological traits of the two hybrid corns SC (S.C. 704) under double cropping in Sari, a split plot experiment as randomized complete block design with four replications was conducted in 2010. Treatments included two densities of 80 and 100 thousand plants per hectare as the first factor and osmopriming of seeds of two hybrids of corn (S.C. 704), with a solution of 10% polyethylene glycol (6000 PEG), 0.5% potassium nitrate (KNO3), 2% potassium chloride (KCl), water (hydropriming) and control (without priming) were considered as the second factor. The results showed that plant height using the priming solution of 10% polyethylene glycol and 100 thousand plants per hectare density was 33 percent higher than 0.5% potassium nitrate and 2% potassium chloride with the density of 80 thousand plants per ha. Also the forage yield per hectare with the density of 100 thousand plants was 14.42% more than 80 thousand density. Best plant density and priming concentration for leaf area index (LAI), crop growth rate (CGR) and net assimilation rate (NAR) were the density of 80 thousand plants per hectare and 10% polyethylene glycol. Therefore, it is concluded that adequate forage yield (54730 kg/ha) of the hybrid corn used in this study were obtained by the density of 100 thousand plants per hectare and 10% polyethylene glycol solution.

To evaluate the effects of seed priming with salicylic acid on quality and baking traits of wheat flour, cv. Alvand, under different sowing dates, a factorial experiment was conducted on the basis of complete randomized block design. The factors were seed priming with salicylic acid (including untreated seeds or control treatment, 400, 800, 1200, 1600, 2000 and 2400 µM concentrations of salicylic acid) and two sowing dates (23rd of Oct. and 22nd of Nov.). Results showed that priming slightly decreased (less than 1%) protein percent compared to control treatment in both sowing dates. It may be due to positive effects of salicylic acid on seed yield and higher accumulation of starch in seeds compared to protein. On the other hand, priming enhanced Zeleny number and loaf volume. Wet gluten, gluten index and seed yield increased by application of seed priming. This was higher in second sowing date compare to the first sowing date. In addition, higher concentrations of salicylic acid lead to more increment in measured parameters.

Delay in planting and low precipitation in wheat (Triticum aestivum L.) farming is the problem in Western Azerbaijan province - Iran. In order to evaluate the effects of seed priming an experiment was conducted under laboratory, green house and field conditions in 2006-7. The experiment was arranged as a factorial in which first factor included of four cultivars (Zarrin, Shahriar, Sardary and Azar) and second factor was including the distilled water, 10% polyethylene glycol (8000), 2.5% KCl, 10% Urea, 4% Micro nutrient, 1000ppm Cycocel (CCC), 20ppm Auxin (IAA) and non priming treatment as control. The maximum water absorbed was for Shahriar with distilled water. IAA and CCC treatments increased seed weight. Analysis of variance showed that the lengths and dry weights of plumule and radical, chlorophyll content, absorbed nitrogen, grain yield and its components, total dry matter and plant height were significantly different (P? 0.05). All of priming treatments had more absorbed nitrogen, grain yield and its components than control. CCC treatment had the highest value of lengths and dry weights for plumule and radical, grain yield, but the lowest value of plant height. In contrast urea had the negative effects for seedling related traits.
