[Biological effect of seed-coating in Carthamus tinctorins].
OBJECTIVE
To study the Biological effect of seed-coating in Carthamus tinctorins.


METHODS
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.


RESULTS
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.


CONCLUSIONS
Seedcoating has significant biological effect in C. tinctorins.
