Abstract:
The influence of different LED light on chlorophyll content of Cymbidium lucky Gloria‘Aguri’×(Cymbidium tracyanum var ‘Huanghua’×Cymbidium mastersii cv ‘Xiaguang’) tissue culture seedling was studied，to provide data support and theoretical basis for tissue culture which was under LED light.The tissue culture seedling grew under different proportions of LED light qualities after a period of time，content of chlorophyll was tested.The results showed that under the RBW(red∶blue∶white=6∶1∶1) treatment，the content of chlorophyll a，b and carotenoid were significantly higher than others，respectively，1.224 5 mg/g，0.738 1 mg/g，0.144 6 mg/g；under the 2RB(red∶blue=2∶1) treatment，all kinds of chlorophyll were relatively low，respectively，0.678 1 mg/g，0.401 0 mg/g，0.079 1 mg/g.It was the most beneficial treatment RBW to Cymbidium lucky Gloria‘Aguri’×Cymbidium tracyanum var ‘Huanghua’×Cymbidium mastersii cv ‘Xiaguang’ synthetise chlorophyll.
