Photosynthetic activity and agrophytocenosis productivity of winter wheat

The authors determined the characteristics of photosynthetic activity of winter wheat's agrophytocenosis as whole physiological productive systems taking into consideration photosynthesis of all plant non-leaf chlorophyll organs. It was shown, that the contribution of these organs to general productivity of photosynthesis of agrophytocenosis for period of plant vegetation in investigated varieties of winter wheat is 31-38,4 %, that suggests the necessity of estimation of photosynthesis in these organs.
