Biological Effect of Seed-coating in Carthamus tinctorins

目的 :研究红花种子包衣的生物效应。方法 :采用SCF1 ,SCF2种衣剂对YM 99和 2 7981 99红花种子进行 3种药种比的包衣 ,室内调查包衣红花种子的发芽势和发芽率 ,田间调查出苗率、苗期生长量及病虫害发生情况。结果 :红花种衣剂能显著提高红花的出苗率、苗期生长量 ,同时有效控制红花生长前期蚜虫、锈病和病毒病的发生。结论

Objective:To study the Biological effect of seed coating in Carthamus tinctorins. Method:Two kinds of seedcoating chemicals SCF1 and SCF2 were used in this experiment.the seed YM 99 and 27981 99 were coated by three kinds of ratio of seedcoating chemicals to seed.It was investigated that the germination energy and germination percentage in the room and the emergence rate,seedling stage growing,pest in the field. Result: Seedoating can improve the emergence rate and seedling stage growing,it also can effectively control aphid,rust and virosis during the growing period in C. tinctorins . Conclusion: seedcoating has significant biological effect in C. tinctorins .ofseed coatinginCarthamust
