不同色光对南板蓝生长的影响

摘要

Objective] To understand the effects of three different basic color light of red, green and blue on the growth of Baphicacanthus cu-sia ( Ness) Bremek.[ Method] The filter equipment was made by ourselves using the materials easily got .Effects of natural sunlight and three color lights(red, blue and green) on the growth of B.cusia were researched.[Result] Red light was the most beneficial to seed germination , followed with natural sunlight;blue took the third place, and green was the last.Growth rate beamed by red light was the largest , followed with natural sunlight; blue took the third place , and green was the last.After qualitative comparison of leaf area, the order was natural sun-light irradiation>blue light irradiation>red light irradiation>green light irradiation.The order of average total branch number was red light irradiation>blue light irradiation >natural sunlight irradiation >green light irradiation.[ Conclusion] Different color lights have different effects on the forming and growing of different plant parts, as well as on the biochemical reactions in plants.Light interference adjustment ac-cording to the current status of plant can offset the natural light deficiency, and promote the better growth of plants.%[目的]了解红、绿、蓝3种不同基础色调的光对南板蓝生长的影响。[方法]运用易得到的材料自制滤光设备，采用不同光质的色光照射南板蓝，研究自然日光与红、绿、蓝3种色光对南板蓝生长的影响。[结果]红光最有利于种子发芽，自然日光次之，再次蓝光，绿光最后；生长量总体上以红光照射最大，自然日光次之，蓝光再次，绿光最后；定性比较叶面积大小顺序为自然日光照射、蓝光照射、红光照射、绿光照射；平均总分枝数大小排序为红光照射、蓝光照射、自然日光照射、绿光照射。[结论]不同的色光对植物不同部分的形成和生长影响不同，对植物内部不同的生化反应影响也不同，有针对地根据植物的现状进行光照干预调节，补充实际中自然光照的缺陷，才能促进植物更好地生长。
