Abstract
This experiment was carried out to investigate the effects of temperature, light quality and gibberellic acid on the seed germination of Rhododendron weyrichii Max. Optimum temperature for germination was 20℃ at constant temperature, but the final germination rate at 15℃ was about the same with the result at 20℃ although its initial germination rate was very low. Significantly enhanced germination rates were attained by alternating temperature under higher temperature such as 25℃ or 30℃. The germination rate was increased by yellow and red light treatments at 20℃, but green light treatment strongly inhibited seed germination at 25℃. Gibberellic acid substitutes light requirement for germination of R. weyrichii seeds.
