摘    要:
对分别来自南带、中带、北带共5个马尾松种源的光合特性进行了研究。结果发现:起源于不同地带的种源对光、温等环境因子有种源特异性的适应特点和需求模式,南带起源的种源在高温强光天气下可以有较强的光合能力,北带种源在温和的环境条件下光合能力较强,中带种源居中。

关 键 词:马尾松  种源  光合特性

Abstract:
The photosynthesis characteristics of the different masson pines were studied.By measuring such photosynthesis factors as net photosynthesis rate(Pn),stomata resistance(Rs) transpiration rate(E) and some environmental factors like the intensity of illumination(Q),air temperature(Ta),relative humidity factor(Rh) and CO_2 concentration and correlating Pn and other photosynthesis and environmental factors,we found that there were the different patterns in the reaction of different masson pines to the environmental factor: the southern masson pines showed high photosynthesis ability under high Q and Ta condition while the northern provenances showed low Pn under same condition.And also we found the content of Pn in the adult leaf of five-year-old tree was higher than that of fourteen-year-old tree.
Keywords:Masson pine  Light source  Photosynthesis characteristic
