摘　　要：用黔草 1号高羊茅种子为试验材料 ,研究其不同千粒重对发芽率、出苗率、出苗速度和成苗率的影响。研究结果表明 :千粒重越大 ,其发芽率、出苗率、成苗率越高 ,出苗速度越快 ,成苗素质越好 ;同时 ,种子的发芽率与出苗率、发芽率与成苗率以及出苗率与成苗率之间存在极为密切的正相关关系。The influence of different seed's thousand-grain weight of Tall Fescue on the germination percentage,the percentage of seed ling emergence,the speed of seedling emergence and the percentage of seedling was studied.The results show that the higher the thousand-grain weight is ,the higher the germination percentage,the percentage of seedling emergence and the percentage of seedling are,the quicker the speed of seedling emergence and the beetter the seedling quality is.In addition,there is close correlation between the germination percentage and the percentage of seedling emergence,between the germination percentage and the percentage of seedling and between the percentage of seedling emergence and the percentage of seedling.
