Title: Studies on the gas exchange characteristics of different cassava varieties.
Abstract: Under field conditions,the gas exchange characteristics of different cassava varieties were studied.The correlations between the net photosynthesis rate and the stomata conductance,intercellular CO_2 concentration,transpiration rate and net photosynthetic rate and the effects of chlorophyll content were studied.The results showed that the correlation among stomata conductance,intercellular CO_2 concentration,transpiration rate and the net photosynthesis rate was highly significantly positive;the main causes for the net photosynthesis rate decline were nonstomatal limitation at earlier growth duration and stomatal limitation at later growth duration.
