Effect of PBZ and moisture stress on photosynthetic pigments (chlorophyll a, chlorophyll b, carotenoids) and agronomic traits (days to heading, days to maturity, number of tillers, numbers of panicles per plant, plant height, shoot biomass, and grain yield). Means followed by the same letter were not significantly different from each other (p = 0.05; n = 10).
