Abstract: The relations among photosynthetic rate , respirational rate and environment factors of Pinus massoniana in east mid-subtropical zone of China were studied with infrared gas analytical apparatus . The results showed that the polycorrelations of photosynthetic rate of the leaves (Pn), light and air temperature were extremely significant , and the regressive formula could be used as the model to estimate the photosynthetic rate .Meanwhile , the corrlations of the daily Pn and the mean air temperature , the respirational rate and the air temperature wer so significant that both the regressive formulas could be used to estimate the yearly Pn and the respirational rate of leaves respectively .The results based on these models of net Pn and respiration (CO2) of P .massoniana were 2.11 104mgdm-2a-1 and 2.38 104mgdm-2a-1 .
