Abstract
This experiment was conducted to investigate the effect of plant hormones on the time-dependent changes of photosynthesis by oxygen electrode system (Rank Brothers Inc. England) and chlorophyll contents in rice(Oryza sativa L. cv. Nihonbare) leaf discs. IAA showed no significant effect when treateds at lower concentration, however IAA 20ppm inhibited slightly the photosynthesis of leaf discs. BA increased strongly the photosynthesis with time. As the BA concentration increased, photosynthesis was significantly stimulated. showed with little effect at lower concentration, however 20ppm inhibited the photosynthesis. ABA inhibited strongly the photosynthesis at all the treatments. IAA, BA, and stimulated chlorophyll contents, but ABA inhibited the chlorophyll contents. It can be concluded that among the plant hormones tested, BA was the most effective in stimulating photosynthesis with time and maintaining the chlorophyll contents.
