Fig. 1From: Effect of sodium silicate on early growth stages of wheat under drought stressThe effect of Si treatment on root/shoot length ratio 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 6.5, 8.7, 13.1 and 26.1 mM. Values followed by the same small letter are not significantly different (p = 0.05)Back to article page
