Fig. 3From: Effect of sodium silicate on early growth stages of wheat under drought stressThe effect of Si treatment on relative water content (RWC) under drought stress. The wheat cultivars Koso (A) and Jokyung (B) were compared. Each group was treated with sterilized distilled water (control), 15% polyethylene glycol-6000 (PEG), and PEG + Si of 26.1 mM. Values followed by the same small letter are not significantly different (p = 0.05)Back to article page
