Abstract
Five wheat cultivars in Hebei Province were used to study the effect of removing leaves after flowering( no defoliation,keep the flag leaves,removing all leaves) on 1000-grain weight of wheat under the conditions of no irrigation( watering before sowing),irrigate one time( watering at late jointing stage),twice( watering at late jointing and heaoling stages) and three( watering at late jointing, heaoting and grain filling stages) times. The results showed that the 1000-grain weight in the treatments of removing leaves were very significantly less than which in the treatment of no removing leaves,the 1000-grain weight was the highest under no irrigation condition and the rate of descend was the maximum under irrigate twice condition. In the later period of wheat, maintaining larger photosynthetic leaves area and proper irrigation was important to improve 1000-grain weight.
