摘　　要：采用室内盆栽试验方法对连续干旱胁迫下的5种燕麦苗期形态特性进行了初步研究。结果表明,在干旱胁迫下5种燕麦的叶片含水量,株高,地上生物量鲜重、干重各指标均有所下降;通过聚类分析将5种燕麦的抗旱性大致分为3类:即强抗旱性牧草有初岛燕麦、哈尔漫燕麦;中抗旱性牧草有早熟燕麦;弱抗旱性牧草有丹麦440、燕麦444。Adopt houseplants test method on five species of oats seedling morphological properties were studied under continuous drought stress in this paper. Results showed that the drought stress 5 kinds of oats leaf water content, plant height, ground biomass of fresh weight, dry weight of each index all declined, By clustering analysis will be 5 oats drought resistance of the roughly classified into three categories： namely strong drought resistance forage have early island oats, Hal aimless oats, In forage have precocious oats drought resistance, Weak drought resistance forage have Denmark 440 oats, oats 444.
