摘　　要：选取白圆叶苋菜、香港种大红圆叶苋菜、耐抽大红苋菜、绿领全红苋菜为试验材料,采用温室盆栽方法进行干旱处理,研究了干旱胁迫下4个苋菜品种的抗旱能力。试验结果表明,香港大红圆叶苋菜的抗旱性最强,耐抽大红苋菜抗旱性次之,绿领全红苋菜抗旱性弱,白圆叶苋菜抗旱性最弱。Taking Baiyuanye amaranth, Hongkongdahongyuanye amaranth, Naichoudahong amaranth and Lvlingquanhong amaranth as materials, we studied the drought resistance of the four amaranth cultivars under drought stress by using pot culture method in greenhouse. The results showed that the cultivar, Hongkongdahongyuanye amaranth, had the strongest drought resistance, and followed by Naichoudahong amaranth and Lvlingquanhong amaranth, while Baiyuanye amaranth had the worst drought resistance.
