The soil column experiment with 3 maize(Zea Mays L.)genotypes(F1 hybrid HD4,♂ 803 and ♀ T4)was conducted to study the profile distribution of root system under water stress and sufficient water supply conditions(40%~45% and 75%~80% of field capacity).The results showed that water stress significantly decreased the total root weight,total root length and total root system surface area of 3 maize genotypes except the total root weight of ♂.As to the profile distribution of root system,water stress distinctive...
