Figure 9

Effects of GABA application on leaf relative water content (A), root activity (30th day) (B), and osmotic potential of leaves (C) or of roots (D) of plants under normal-temperature and high-temperature stress. Vertical bars above curves in (A), (C), or (D) represent the least significant difference (LSD) values at a particular day (n = 4; p ≤ 0.05). The vertical bar above the column in (B) represents + SE of the mean (n = 4) and the different letters in the columns indicate significant differences based on LSD (p ≤ 0.05). C, control (normal condition); C + GABA, control plants pretreated with GABA; H, heat stress (normal condition); H + GABA, heat-stressed plants pretreated with GABA.
