Title: 溫度, 光 및 Gibberellic Acid 處理가 참꽃나무의 種子發芽에 미치는 影響
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.
