为了研究油桐二代优树及控制授粉子代光合效率及其光合特性参数之间的差异情况,从而筛选出高光效的品种,以湖南、湖北、重庆、四川、广西、贵州等省区的不同品系二代优树及控制授粉子代植株为试材,利用Li-6400便携式光合测定系统,对其主要光合性状指标进行了测定与分析。结果表明：（1）油桐二代优树光合效率存在一定差异,利用聚类分析,可将12个不同种源的二代优树划分为3类,其中,‘红岩3号’‘五家铺26号’‘五家铺35号’‘芦溪2号’‘五家铺42号’‘西岐1号’和‘红岩4号’的光合特性均较优;（2）不同优树自交、杂交子代的光合特性之间有所差异,杂交子代具有一定的杂种优势;（3）油桐主要光合...

In order to research the differences of photosynthetic efficiencies and parameters among second generation superior trees and control-pollinated progenies in Vernicia fordii, to screen some cultivars with high photosynthetic efficiency, using some second generation superior trees and control-pollinated progenies from different strains in different areas as materials, the main photosynthesis characteristic indexes were measured by Li-6400 portable photosynthesis system and determined. The results showed that photosynthetic efficiencies among the...
