摘　　要：玉米从播种到出苗这一阶段对水分十分敏感。这一时期土壤水分不足 ,影响到萌发出苗 ,给玉米的播种、全苗、壮苗造成了很多困难。近些年来国内外对芽苗期抗旱性与抗旱机理的研究主要有以下几个方面 :水分胁迫对玉米种子萌发生理生化反应的伤害 ;玉米芽苗期抗旱性的评价 ;玉米芽苗期抗旱性的遗传及育种等。Maize is very sensitive to water stress in seedling emergence Water stress reduces the germination percentage seriously It makes lots difficult to keep full and strong seedlings The injury to physiological and biochemical reaction , the evaluation of drought resistance and the inheritance and breeding of drought resistance in maize seedling emergence were reviewed in this paper
