| 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 $20^{circ}C$ at constant temperature, but the final germination rate at $15^{circ}C$ was about the same with the rates were attained by alternating temperature under higher temperature such as $25^{circ}C$ or $30^{circ}C$. The germination rate was increased by yellow and red light treatments at $20^{circ}C$, but green light treatment strongly inhibited seed germination at $25^{circ}C$. Gibberellic acid substitutes light requirement for germination of R. weyrichii seeds. |
