Role of silicon in drought stress to plants.?

Question

like role of silicon in drought on mung beans plants

Answer 1

A study on the effects of silicon supply on the resistance to drought in cucumber plants was conducted in pot experiments. The results suggested that in the absence of stress, silicon slightly enhanced the net photosynthetic rate, but significantly decreased the transpiration rate and stomatal conductance in cucumber plants. Silicon enhanced the net photosynthetic rate of cucumber plants under drought stress. Since silicon decreased the stomatal conductance, enhanced the capacity of holding water, and kept the transpiration rate at a relatively steady rate during drought stress, the photosynthesis of the cucumber plants was sustained.
