The aim of this research was to determine whether the brassinolide and spraying time of this hormone in two stages of applying irrigation interruption could be improved the quality of produced grain wheat during 2014-2016. Irrigation regimes were carried out at irrigation interruption from the flowering and grain-filling stage and full irrigation as a control. The second factor was including factorial of zero, 0.05, and 0.1 mg l-1 of brassinolide and spraying time before the flowering and grain-filling stages. The maximum grain weight had no significant difference between the both irrigation interruptions. The lowest period and the highest rate of grain filling were observed after irrigation interruption in the flowering stage. The seed germination and vigor index of seedlings were increased in irrigation interruption at the flowering stage and without the spraying of hormones. The foliar application of 0.1 mg l-1 brassinolide caused the highest seedling vigor index and the lowest electrolyte leakage from grain. Overall, the application of 0.1 mg l-1 brassinolide improved the quality of wheat seed affected by the irrigation interruption at the flowering and grain-filling stages in water restriction.

In order to investigate the effect of seed bio-inoculation with plant growth promoting Rhizobacteria on germination and seedling indices of cumin under salinity stress, an experiment was laid out based on a completely randomized design with two factors and four replications in 2017 at Seed Science and Technology Laboratory, Yasouj University, Iran. Experimental factors included bio-inoculation with 3 strains, viz. PF2, PF25, and CHA0 of Pseudomonas fluorescents, and Bacillus subtilis and non-primed (control) and three levels of salinity stress (0, -4 and -8 bar). Results indicated that salt stress reduced germination (up to 40%) and seedling indices of cumin under -4 and -8 bar, the highest germination percentage, germination rate, seedling length, and seedling vigor index were achieved in the seeds inoculated with P. fluorescens, CHA0. At all levels of stres...

Also, light can affect the germination percentage of rapeseed at different temperatures, but the response of rapeseed to light, especially at lower and higher temperatures, has not been studied. Therefore, this study aimed to investigate the changes in the germination of rapeseed cultivars at different temperatures and determine cardinal germination temperatures based on germination percentage and rate under both the presence and absence of light conditions. Materials and methods: In this study, germination tests were carried out at 5, 10, 15, 20, 25, 30, 35, 37, and 40°C temperatures in two light conditions (12 h light / 12 h dark) and darkness on nine spring cultivars (Traper, Agamax, Hayola-50, Hayola-420, RGS, Mahtab, Hayola-61, Zafar, and Zarfam) and one winter cultivar (Garo). The four-parameter Hill model was used to describe germination changes over time and the dent model was used to calculate cardinal temperatures. Seed viability at lower and higher temperatures was evaluated by the tetrazolium test. Results: The evaluation of the trend of cumulative germination percentage over time in different cultivars showed that maximum germination percentage of all cultivars happened in the temperature range between 15-30 °C, some in the temperature range of 10-30 °C (Hyola-61) and others even in the temperature range of 5-30 °C (RGS, Mahtab, Garo, Zafar, and Zarfam) had the highest germination percentage. The highest germination rate in all cultivars was observed at the temperature range of 22-35 °C. Light only had an effect on the germination percentage of the seeds at sub and super optimal temperatures. At these temperatures, light increased the germination percentage. The remaining seed of 5, 10, 35, 37, and 40 °C temperature after transfer to 20 °C did not germinate, whereas most of them were viable based on the tetrazolium test. Conclusion: The difference in the optimum temperature range for germination percentage and rate showed that to optimize seed performance, the optimal temperature range between the germination percentage and germination rate should be considered as the optimum temperature for germination. At sub and supra optimal temperatures, light leads to improved germination in some cultivars. The effect of light on germination at supra optimal temperatures was far higher than that of sub-optimal ones. Survival of the remaining seeds at the sub and supra optimal temperatures in some cultivars provided evidence of thermodormancy in these cultivars, this issue needs further investigation in the future.

Salinity stress was stimulated by elevating the electrical conductivity (EC) of a nutrient solution by a proportional increase in the content of all macro-and micronutrients. In 2009-2010, tomato plants were grown on rockwool, in a heated foil tunnel. The experiment included two sub-blocks with two EC levels (2.5 and 4.5 mS cm-1). Within each sub-block, the following foliar application variants were distinguished: 1. control, without foliar application; 2. salicylic acid (SA); 3. SA/KMnO 4. In the SA/KMnO 4 combination, solutions of these compounds were applied alternately every 7 days. SA was applied in the concentration of 0.01%, while the concentration of KMnO 4 was 0.1%. Foliar treatments were conducted at 7-day intervals from the 3 rd cluster flowering stage until ten days before the first harvesting of fruits. Irrespective of the EC of the nutrient solution, foliar application of SA as well as SA/KMnO 4 had no significant effect on the tomato yield, total acidity and dry matter or soluble sugar content in fruits. Neither did it affect significantly the mineral status of plants except for an increase in the Mn level induced by SA/KMnO 4. A significantly higher content of ascorbic acid together with a decreased content of phenolic compounds and free amino acids resulted from the foliar application of SA and SA/KMnO 4. Salicylic acid counteracted the oxidative stress caused by KMnO 4 .
