发光二极管（LED）红蓝光照对不同水稻品种秧苗素质的影响
Effects of Red and Blue Illumination from Light-emitting Diode(LED)on Seedling Quality of Different Rice Cultivars
摘要
Abstract
In order to probe the illumination-requirement law of raising rice seedlings and promote the factory production of raising rice seedlings,two rice cultivars(Hefeng and Huangxiu)were used to study the effect of red and blue illumination from light emitting diode(LED)on the quality of seedlings.The results showed that seedlings growth was affected by LED red or blue illumination treatment,leading to the decreased quality of seedlings compared with CK(conventional fluorescent light).Total content of photosynthetic pigments decreased more under long-time LED blue illumination than under LED red illumination,while the contents of chlorophyll a and carotenoid maintained a higher level in treatment of LED red illumination.Further study showed that blue illumination treatment inhibited the root elongation,root length and plant height of rice seedlings,but increased the root number,stem thickness and dry matter accumulation,so the sound seedling index was superior to that of red illumination treatment.It implied that LED monochrome blue or red illumination would not meet the illumination requirement in factory production of raising rice seedlings.关键词
