Abstract
Objective: To investigate the effects of aluminum(Al) stress on photosynthetic characters of rape leaves.Methods: With three rape(Brassica campestris L.) cultivars Ganyou No.1,Ganyou No.2 and Xiangyou No.3 as test materials,this paper investigated the effects of different Al concentrations on photosynthetic characters of rape leaves.Results: The results showed that the chlorophyll a decreased by 2.8%～17%,the chlorophyll b decreased by 4.2%～17%,the carboxylation efficiency of RuBPCase decreased by 7%～28%,the photosynthetic rate decreased by 6%～22%,the root shoot ratio decreased by 8%～35% in response to Al stress.Conclusions: Al stress could inhibit the photosynthesis of rape leaves.In addition,three test rape cultivars had definite genetic difference in response to Al stress.
