光质对灵芝生长与灵芝多糖含量的影响

目的:研究不同光质对灵芝生长发育和灵芝多糖含量的影响,为灵芝优质高产栽培提供理论依据。方法:栽培灵芝时进行不同光质处理,在灵芝不同生长发育时期观测其形态变化并测量多糖含量。结果:不同光质处理形态上弹孢前期灵芝菌盖厚度与菌盖表面环纹的数目与对照差异显著,灵芝多糖含量出现最高值时期不同。蓝色光质处理在现蕾期、开伞期、弹孢后期多糖含量均高于对照,且差异显著。绿色光质处理有助于生长末期多糖积累。不同光质处理对灵芝子实体产量与灵芝孢子粉产量均有影响。结论:对照处理灵芝子实体产量高,性状好;蓝色光质处理可以提高灵芝多糖含量。

Effect of light quality on growth and polysaccharides content of Ganoderma lucidum

Objective : To study the effect of light quality on growth, polysaccharides content of Ganoderma lucidum. Method : G. lucidum was planted under different light qualities. The growth of G. lucidum was observed and polysaccharides content was determined in different growth periods. Result : There were significant differences in the form of the thickness and the numbers of ringed of the fruit before the ejection. The maximum content of G. lucidum polysaccharides under different light qualities were appeared in different periods. The content of polysaccharides was higher than that of CK under blue light in the period of budding, parachute phase, after spore ejection. The content of polysaccharides was increased under green light in the period of growth stage. The yield of fruits and spores were different in different light qualities. Conclusion : The light quality could increase the content of polysaccharides in G. lucidum.
