Title: Study on Photosynthetic Characteristics of Different Tobacco Genotypes in Panzhihua Tobacco Area
Abstract: The 8 different tobaoco genotypes were used to study the photosynthetic characteristics of tobaoco. The photosynthetic rate,intercellular CO2 concn,stomata conductance,transpiration rate,and leaf temperature of tobaoco leaves were determined by using the Li-6400 portable photosynthesis system under natural light in this paper. The results showed that the photosynthetic rate of ‘09011'( Q1) was highes;t ‘ NC71' and Honghuadajinyuan were higher; ‘K326',‘Yunyan 203' and ‘NC102' were middle; ‘Yunyan 317' and ‘Yunyan 105' were lower. The photosynthetic rate of different layer in tobaco leaves were highly significant differences,which was upper middle lower paets; the intercellular CO2 concn of different layer in tobaco leaves were highly significant differences; the stomata conductance,transpiration rate,and leaf temperature were no significant difference in different layer in tobaco leaves.
