Physiological response of soyabeans to water deficit in two cerrado soils



Physiological response of soyabeans to water deficit in two cerrado soils



Pesquisa Agropecuaria Brasileira 16(5): 669-675



The response of 2 soyabean to different degrees of water stress in (a) clay and (b) sandy clay soil was studied in a greenhouse. Soil water content for the same degree of plant water stress differed between soils, but values of relative water content, leaf water potential and stomatal diffusive resistance showed that stomata closed at leaf water potential of 10 bar in both soils, corresponding to soil m.c. of 25.5 and 19% in (a) and (b), respectively.
