LEAF SURFACE FORMATION, PHOTOSYNTHETIC ACTIVITY, BIOLOGICAL MASS AND PHOTOSYNTHETIC PRODUCTIVITY IN WINTER WHEAT

Abstract

This in the article autumn of wheat vegetation during leaf level formation dynamics , leaves photosynthesis of activity physiological indicators , biological mass accumulation and photosynthesis productivity indexes studied . Research results autumn in wheat leaf apparatus formation type , variety genetic potential , agricultural technology and ecological to factors strong related that it is shows . Leaf level index (LAI) 4.5–6.0 units in the range was in options from the light use coefficient maximum at the level manifestation Photosynthesis speed , chlorophyll (a + b) concentration and nett - assimilation coefficient high was in plants dry substance accumulation increased by 22–27% . Obtained results photosynthetic of the apparatus morphophysiological the state of grain yield in the formation main manager factor to be counted confirms
