Abstract
In order to study the photosynthetic characteristics of pepper leaves at different leaf positions, we carried out the pot experiment and determined the photosynthetic parameters by LI-6400 XT portable photosynthetic apparatus. The results showed that, different leaves had different net photosynthetic rate, stomatal conductance, intercellular CO2 concentration and transpiration rate, and the leave at the third leaf position had the highest net photosynthetic rate, which was extremely significant higher than those of other leaf positions, moreover, the net photosynthetic rate of the leaves of different leaf positions had a significant negative correlation with intercellular CO2 concentration.
