[Biological effect of seed-coating in Carthamus tinctorins].

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.
