Effects of silicon on the biochemical characteristics of wheat under drought stress conditions
Keywords:protein, proline, grain yield, catalase
The country can be further assisted to achieve food security by finding a solution to reduce the quantitative and qualitative yields of wheat. Effects of drought stress on the biochemical characteristics of wheat under drought stress conditions were investigated in a factorial experiment as a randomized complete block design with three replications in the research field of the Soil and Water Research Institute in the 2018-2019 and 2019-2020 crop years. Experimental treatments were drought stress at three levels without stress, mild stress, and severe stress with 75, 50, and 25% usable moisture in the soil as the first factor. The second factor was potassium silicate at four levels of a Si-free control, 20 kg/ha as soil application at the bolting stage, and spraying at 2.5 and 5 kg/ha at bolting, heading, and seed dough stages, which were examined in the Sivand wheat cultivar (drought-sensitive) for 2 years.
