摘　　要：本研究针对拉萨市场上常见的多年生牧草紫云英、小冠花、沙棘和砂生槐种子进行不同时间酸处理的萌发试验研究,旨在探索出适合于西藏的4种多年生牧草种子的酸处理时间。结果表明,浓硫酸处理120 min的砂生槐种子的发芽率达到72.22%,显著高于其余处理(p<0.05)。紫云英种子的发芽率总体变化趋势随着酸处理时间的延长变化不大,在浓硫酸处理30 min时发芽率达到25.56%;小冠花种子在浓硫酸处理15 min时的发芽率达到92.22%;沙棘种子在浓硫酸处理15 min时的发芽率达到90.00%。In this study, the seed germination test of acid treatment time on Astragalus sinicus L., Coronilla varia L., Hippophae rhamnoides Linn. and Sophora moorcroftiana, which are common in Lhasa market, was studied in order to explore the suitable acid treatment time for four perennial herbage seeds in Tibet. The results showed that the germination rate of Sophora moorcroftiana seeds treated with concentrated sulfuric acid for 120 minutes was72.22%, which was significantly higher than that of other treatments(p<0.05). The germination rate of Coronilla varia L. seeds in concentrated sulfuric acid treatment for 15 minutes reached 92.22%.The germination rate of Hippophae rhamnoides Linn. seeds under concentrated sulfuric acid treatment for 15 minutes reached 90.00%.
