[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.


METHODS
G. lucidum was planted under different light qualities. The growth of G. lucidum was observed and polysaccharides content was determined in different growth periods.


RESULTS
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.


CONCLUSIONS
The light quality could increase the content of polysaccharides in G. lucidum.
