RESUMEN
OBJECTIVE: To study the effect of light quality on growth, antioxidant enzyme activities of Ganoderma lucidum mycelium. METHOD: G. lucidum mycelium was cultured under different light qualities by light emitting diodes (LED). The growth G. lucidum mycelium was observed and antioxidant enzyme activities was determined in different growth periods. RESULT: Under the red LED, the blue LED and dark condition (CK), the mycelium grew faster than that under other light qualities. The white LED resulted in a largest increase in the amount of the mycelium and always kept the activities of CAT high level. Major fluctuations of POD activities emerged under the green LED, while enhanced severely in the late phase. Under the yellow LED, the activities of SOD appeared high level. However, SOD activities on dark (CK) raised obviously in late period. At the late stage, the content of mycelium polysaccharides was significant higher than that under the blue LED. CONCLUSION: The light quality could influence the growth and metabolism of G. lucidum mycelium.

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.
