摘　　要：采用Li-6400光合分析仪,研究了11种泡桐无性系在不同光合有效辐射(PAR)强度下叶片的光合作用,结果表明:11种泡桐无性系对强光的适应性都较强,属于强阳性树种;11种泡桐无性系的光合特性各有不同,并可分为4类,不同类表现出不同的光合特性。The leaf photosynthesis of 11 kinds of paulownia clones under photosynthetic effective radiation（PAR） at different intensities were studied by using Li-6400 photosynthesis system.The results showed that 11 kinds of paulownia clones had stronger adaptability to strong light,belonging to sunlight loving tree species.Their photosynthetic characteristics had their own difference.They could be divided into 4 categories with different photosynthetic characteristics.
