摘要
以福建产金线莲(Anoectochilus roxburghii)为材料,研究不同LED光质(红光、黄光、蓝光)对金线莲生长指标以及叶绿素、气孔的影响。结果表明,红光与黄光有利于金线莲株高增长,与对照相比分别提高18.74%、21.47%,但二者处理的植株较为瘦弱,且红光和黄光处理下的植株叶绿素a和叶绿素b含量较低。蓝光处理下金线莲生长情况较好,叶面积与对照相比增长明显,且叶绿素含量相对较高。不同LED光质处理下的植株气孔频度、长度、宽度与对照相比都有一定增长。
Anoectochilus roxburghii was used for the study of the effect of different light of light-emitting diode （red, yellow, blue） on its growth index, chlorophyll and stoma. The results showed that red and yellow light were better for the plant height which increased by 18.74%, 21 .47%, respectively. But the content of chlorophyll a and chlorophyll b under red and yellow light treat are lower than CK and the plants are weaker. A. roxburghii grew well under blue light, leaf area, and the content of chlorophyll increased a lot than those of CK. The frequency, length and width of each treatment plant stoma have a certain growth.
