Abstract: (138 Views)
In order to evaluate the effect of boron and jasmonic acid foliar application on maize, under different irrigation regimes, an experiment was conducted as split-split plots in the form of a randomized complete block design in three replications in the summer of 2021 in the Varamin. In this experiment, irrigation was arranged in four levels (as the main factor): complete irrigation, stopping irrigation at the 8-leaf stage, stopping irrigation at the stage of cob emergence, and stopping irrigation at the stages of 8 leaves and cob emergence. Boron foliar application at three levels, including spraying with pure water, spraying with 0.5% boron, spraying with a solution with 1% boron, and spraying with jasmonic acid solution in three levels, including spraying with pure water, spraying with a concentration of 50 µM jasmonic acid, and spraying with a concentration of 100 µM jasmonic acid, were considered in sub-plots. The results showed that stopping irrigation at different stages of growth caused a decrease in all tested traits. Also, the results show that the spraying of 1% boron increases grain yield (5.5%), 1000 seed weight (2.9%), biological yield (2.8%), carotenoid content (11.2%), and decreases 4.4% of leaf malondialdehyde. On the other hand, the use of 100 µM jasmonic acid increases leaf chlorophyll content (2.69%), leaf carotenoid content (2.94%), 1000-seed weight (1.29%), seed yield (2.67%), and biological yield (2.95%). Indeed, the use of jasmonic acid also reduced the damage caused by oxidative stress by increasing the amount of the superoxide dismutase enzyme.
