摘要:
Through analyzing the various position leaves character of 3 ages bamboo, including net photosyntheticrate, light respiratory rate, dark respiratory rate, CO2 compensation point and light compensation point, in five-years - old forest during different growing shoot stages in stated - own forestry farm of Nanjin, results showed thatleaves had vigorous physiological function during prosperity stage of growing shoot. Net photosynthetic rate was high-er, light respiratory rate, dark respiratory rate, CO2 compensation point and light compensation point were lower,the photosynthetic coefficients was larger.2- year bamboo and 3 - year bamboo had stronger photosynthetic ability. Different photosynthetic and respiratory indexes of various position leaves were not consistent, but in generally, mid-dle leaf had stronger assimilation ability.
