Fig. 1From: Silicon-induced thermotolerance in Solanum lycopersicum L. via activation of antioxidant system, heat shock proteins, and endogenous phytohormonesEffects of silicon (Si) application on the growth parameters of tomato plants grown under normal and heat stress conditions. a Shoot length, b Shoot dry weight, c stem diameter, d root dry weight, e root length, f effect of Si on the phenotype of tomato plants in the presence or absence of heat stress. Values are presented as the mean ± SE (n = 15). Different letters in one measure indicate a statistically significant difference at P < 0.005Back to article page
