Abstract:
Effects of drought stress on water consumption and canopy development in four summer soybean genotypes of Wuxing 3，Jidou 15，Jidou 16 and Jidou 17 were studied under rain shelter condition.The results showed daily water consumption was lower within the 20 d after seedling，much higher daily water consumption was observed from early flowering to early pod filling，with a peak around early flowering.The maximum of leaf area index (LAI) occurred at full flowering.Periodical drought stress led to reduced LAI in most of the varieties.In terms of canopy development，Jidou 16 was more resistant to drought at seedling，Wuxing 3 was more drought resistant at middle and late growth stages，and Jidou 15 at late growth stage.The varieties of Wuxing 3，Jidou 15，Jidou 16 had similar LAI，whereas Wuxing 3 consumed much less water than the other two varieties.Jidou 17，with the greatest LAI，also used the greatest amount of water in the four varieties.The main water consumption soil layer of soybean was 0-100 cm.Soil moisture condition in 0-50 cm layer was most important to the growth and development of soybean plant
