不同光质LED光源对金线莲组培苗生长的影响

o discuss the effect of different light quality and the light intensity treatment on the growth of Anoectochilus roxburghii tissue culture seedling ,the LED light source was used as an artificial light source for Anoectochilus roxburghii in Zhang Zhou to subculture and rooting culture, the results showed that, 70μmolom-2os-1 red light treatment is to the benefit of the growth of Anoectochilus roxburghii height , but go against to take root; it is not obvious that the effect of Green light for the indicators of Anoectochilus roxburghii , and no significant difference between different intensity; a promoting effect on leaf growth of tissue culture seedling and accumulation of biomass and root growth of Anoectochilus roxburghii under the 70μmolom-2os-1 blue light treatment, but certain inhibitory effect on plant height. Conclusion: the red light is advantageous to the growth of aerial parts of plants, the green light have little impact on plant photosynthesis, and certain effect on dwarfed and strong seedling of tissue culture seedling under the blue light.
