- Abstract
In order to improve the utilization efficiency of hybrid rice seeds, the effects of seed-coating agents on hybrid rice seeds with dehiscent glumes were investigated. Total six kinds of seed-coating agents were selected, i.e., 20.5% imidacloprid·prochloraz FS, 30.5% imidacloprid ·prochloraz FS, 23.0% thiamethoxam ·hymexazol·prochloraz FS, Ruisheng WS, Shileshi FS and Liangdun FS, and their effects of seeds of Longliangyou Huazhan and T You 272 were investigated. The results showed that when the percentage of glume-dehiscent seeds reached 10%,20.5% imidacloprid·prochloraz significantly improved the germination rate of Longliangyou Huazhan, which was 4.33% higher than that in the control group, and the seedling rate of Longliangyou Huazhan remained unchanged; 30.5% imidacloprid·prochloraz did not improved the germination rate of T You 272, but improved its seedling rate, which was 7.66% higher than that in the control group. When the percentage of glume-dehiscent seeds reached 20%, 20.5% imidacloprid·prochloraz and 30.5% imidacloprid·prochloraz improved the germination rate of T You 272 by 3.50% and 4.83%, respectively, and its seedling rate did not decline. In conclusion,seed-coating agents have certain repair effect on glume-dehiscent rice seeds; 20.5%imidacloprid·prochloraz and 30.5% imidacloprid·prochloraz could improve the efficiency of Longliangyou Huazhan and T You 272 with small amounts of glume-dehiscent seeds.
