毛竹叶片Pn与光照强度 (L)、气温 (T) 多元相关呈极显著水平，其回归方程可作为光合速率估算的模型；日光合量与平均气温呈极显著线性正相关，呼吸速率与气温呈极显著相关，其回归方程均可作为叶片日光合量、呼吸速率的估算模型。毛竹的年净光合量、年呼吸量估算结果分别为 1.81×104、2.00×104 mgCO 2·dm-2·a-1。
The relationship between photosythesis and respiration of Phyllostachys heterocycle cv. Pubescens and environmental factors was studied. The results were as follows: The photosynthetic rate(Pn) was most significantly corelated to Light (L) and temperature(T) and the regressive equation could be used as a model to estimate the photosynthetic rate. The daily Pn and respiration rate were significantly corelated to air temperature and they could be estimated by regressive equations. The estimated annual photosynthetic amount and respiration amount were 1.81×104 and 2.00×104 mg CO 2 dm-1.a-1, respectively.
