大豆、玉米种子的千粒重与发芽成苗关系的研究

Study on the Relation between Seed Germination,Seedlings Development and Seed’s Thousand-grain Weight of Soybean and Maize

以大豆、玉米种子为试验材料 ,研究了其不同千粒重对发芽率、出苗率、出苗速度和成苗率的影响。结果表明 ,千粒重越大 ,其发芽率、出苗率、成苗率愈高 ,出苗速度愈快 ,成苗素质愈好。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相关关系。

The influence of different seed's thousand-grain weight of soybean and maize on the germination percentage,the percentage of seedling emergence,the speed of seedling emergence and the percentage of seedling was studied.The results are 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 is and the better 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.
