基于单片机 LED 光源在植物组培中的应用研究

摘要

According to the fact that plants grow and evolve in full sunlight and selectively receive balanced lights , we conducted a series of experiments on tissue culture of different plants about light quality , different patterns and the man-ners of working used us Independently Design “Based On SCM LED Light Source”.The results showing: In the corn germ sprout experiment , Red blue group better than any other groups has the maximum number of the germination with a rapid growth rate .The influence on the growth rate of green beans experiment , the intermittent light way is superior to cntinuous and flashing light ways , use"LED-72-50-16/8"the growth rate increase 33%.Promote differentiation and the growth of potato points experiment , provide Red and blue light the growth rate is the best , When the red and blue light provide time different , provide both at the same time the longer the time better .%基于植物是在全谱太阳光下进化、生长，选择性的接收各种平衡光色的事实，利用自主设计的“基于单片机LED 光源”进行了光质、给光方式以及给光时段对不同组培苗生长影响的实验。结果表明：在玉米胚发芽实验中，红蓝光组发芽数最多，增长迅速；对绿豆组培苗生长速率影响，间歇给光优于连续给光方式，用“LED-72-50-16/8”处理，干重提高33％；促进马铃薯芽体分化以及生长，同时供应红光与蓝光，生长速率最佳；给蓝光的时机影响生长速率，给于开始阶段者最佳。
