Abstract

The dynamic change of moso bamboo （Phyllostachys edulis） canopy parameters，including total chlorophyll content （TCC），leaf area index （LAI），canopy closure （CC） during the bamboo shooting growth phase was examined，and the relationships between these canopy parameters and photosynthetic active radiation （PAR） were analyzed. Results showed （1） increases in TCC，LAI，and CC during the bamboo shooting growth phase；（2） that the relationship between a mother bamboos TCC and PAR in the prior leaf development stage （R = 0.570，P = 0.180） was higher than in the posterior leaf development （R= 0.140，P = 0.860）； and （3） after leaf development，PAR had a positive correlation with LAI （R2 = 0.796 0，P = 0.120） and a significantly positive correlation with CC （R2 = 0.991 6，P = 0.004）. This result implied that the priority for delivering photosynthetic products from the mother bamboo was to shoot before leaf development. The correlation analysis showed that the Phyllostachys edulis canopy enhanced solar energy allocation and utility.［Ch，6 fig. 24 ref.］
