In order to improve its yield, the proper method for higher density breeding should be applied to screen the better inbred lines of maize. 为了进一步挖掘玉米自交系的产量潜力，应广泛采用高密度选系手段，通过创造适当的逆境以筛选无秃尖的自交系。
In this study, the physiological characters and phosphate assimilations of maize inbred lines with different drought resistance were studied under water stress. 摘要以抗旱性不同的玉米自交系为材料，研究了大喇叭口期水分胁迫对其生长的影响及生理指标的变化与抗旱性的关系。
