摘　　要：研究三种针茅种子的萌发特性及其幼苗生长,发现三种针茅种子的最适萌发温度有一定差异性;通过测定种子活力了解到大部分的种子处于休眠状态;成苗后的针茅地上地下生长规律基本符合Logistic曲线。The germination and seedling growth of three of Stipa species were studied, and it was found that their optimal germination temperature are different; most of seeds are in dormancy state by examining the seed vigor, the aboveground and underground growth of Stipa accord with Logistic Equation.
