| 摘 要： | 本文研究了我国荒漠植物的水分饱和亏, 结果以典型的荒漠旱生植物珍珠和红砂最大, 分别为43.4%和35.6%, 梭梭34.7%, 籽蒿37.1%。中生植物刺槐和钻天杨水分饱和亏最小, 分别为15.0%和14.3%。这就表明, 荒漠植物在干旱条件下, 免于伤害的能力与水分饱和亏的大小密切相关。

| Abstract: | Relationships between water saturation deficit(W S D) and drought resistance for some sand-fixing plants and desert plants were studied. The W S D for desert plant species, Salsola passerina and Reau-muria Soongorica is 43.4% and 35.6%, sand-fixing plant species, Haloxylon ammodendron and Artemisia sphaerocephala 34.7% and 37.1%, mesophyte species Robinia pseudoacacia and Populus nigra var. thevestina 15.0% and 14.3% respectively. The results showed that the drought resistance of each of the studied plant species is basically consistent with the W E D it can suffer. |
