FIGURE 3.
Glutathione (GSH), glutathione reductase (GR), and glutathione disulfide (GSSG) levels in rice leaves as affected by growth regulators under heat stress. HDT, HNT, and AT stand for high day, high night, and ambient temperature, respectively. The lines on bars represent LSD value for the interaction of PGRs and heat stress (heat stress × PGR) at α = 0.05.
