摘　　要：通过对在水分胁迫下的鲁梅克斯K 1杂交酸模幼苗生理指标的测定 ,研究了其苗期的抗干旱能力。试验结果 :鲁梅克斯K 1杂交酸模苗期具有一定抗旱能力 ,但随胁迫时间的延长 ,其细胞膜伤害率成倍增加 ,叶绿素含量相对减少 ,旱害表征逐渐明显。The drought-resistant ability of the seedlings of Rumex K-1 hybrid(Rumex patientia × R.Tianschanicus,cv.Rumex K-1) was studied and the physiological indexes were measured. The results showed that the seedlings of Rumex K-1 hybrid under the drought stress prolonged, the damage rate of cell membrane was increased two times and the content of chlorophyll decreased gradually. The character of drought-harm became obvious. =
