苎麻属野生种的光反应类型研究

对苎麻属11个野生种资源进行了10h、13h、16h光照处理，在不同光长条件下，表现出短光照生育期缩短、长光照生育期延长；短光照生育期延长、长光照生育期缩短；长、短光照生育期都延长；长、短光照生育期都缩短四个类型，并且不同光照时间对不同的生殖生长期有不同的影响，生长发育的积温差异较大。

Studes on the Light Reaction Types of Wildtype of Boehmeria

Eleven wildtype resource of Boehmeria L were treated by illumination for10,13,16h each under different culture conditions.There appeared four phenotypes:1.short-day plants'growth period shortened under short illumination and long-day plant's growth period extended under long illumination,2.short-day plants'growth period extended under short illuminattion and long-day plant's growth period shortened under long illumination;3.growth period shortened under both long and short illumination,4.growth period extended under long and short illumination.Also different illumination treatment had different effect on reproduction,and the accumulated temperatures varied greatly.
