[Effects of A, D-genome chromosomes on photosynthetic carbonassimilation in common wheat] [In Process Citation]

Photosynthetic traits of ditelosomic lines with A, D-genome in CS (Chinese Spring) were investigated in this paper. The both arms of 4A-chromosome have the positive effects on photosynthetic rate, active photosynthetic duration(APD), chlorophyll content and mesophyll conductance. The short arms of 1A and both arms of 6D also have positive effects on photosynthetic rate and APD. But the long arms of 4D have negative effects on photosynthetic rate, APD and RuBPCase activity. The short arms of 2A, long arms of 5A, 6D and 7D negatively affect on RuBPCase content. So, 4A, 4D and some other chromosomes have shown important effects on photosynthesis in common wheat.
