Heterosis Analysis of Photosynthetic Index of Capsicum annuum var.conoides in Seedling Stage
摘要
Abstract
In order to select high photosynthetic efficiency combinations of Capsicum annuum var.conoides varieties,the net photosynthetic rate(Pn),intercellular carbon dioxide concentration(Ci),stomatal conductance(Gs),water use efficiency(WUE),transpiration rate(Tr)and chlorophyll content of different C.annuum var.conoides varieties and their hybrid combinations at seedling stage were compared,and the correlation between heterosis and photosynthetic indexes was analyzed.The results showed that the four hybrid C.annuum var.conoides had significant heterosis at seedling stage,and the net photosynthetic rate,stomatal conductance and transpiration rate showed significant high parental heterosis,and the net photosynthetic rate was positively correlated with transpiration rate.Among them,the high parental dominance of net photosynthetic rate and stomatal conductance of'206'×'Tianyu'were 42.99%and 63.52%,respectively,while the high parental dominance of transpiration rate was 92.16%,which had strong photosynthetic capacity and was a combination with potential development value.关键词
