Abstract:【Objective】The experiment was conducted to study the influences of coating treatment with cold indicated seed-coating agents on the rice seed’s germination at a normal temperature and low temperature.【Method】No.31 Xiangzaoxian (conventional rice) and No.1 Y Liangyou (super hybrid rice) were chosen as the rice seed material using the soaking agent ‘Qimiaokuai’ developed by South China Agricultural University, combined the seed dressing agents commonly used in Heilongjiang Reclamation, and added germicidal agents, pesticides, adhesives with other substances mixed as the seed coating agent. Three treatments included soaking and accelerating germination(CK), coated without soaking(A) and coated after soaking(B). The effects of coating treatment on different genotypes rice seed’s germination and seedling quality were studied in this paper.【Result and conclusion】The results showed that for coated treatment, at a normal temperature, the seed germination time lengthened, but germination rate increased. The germination rate of No.1 Y Liangyou coated without soaking and coated after soaking treatment respectively increased by 11.10% and 16.55% compared with control, and No.31 Xiangzaoxian increased by 30.83% and 37.68%, respectively. Under low temperature conditions, the germination decreased because of the cold infestation. Coating treatment improved the seedling rate of rice, and the rice which were coated after soaking (B) had the highest seedling rate, with No.31 Xiangzaoxian and No.1 Y Liangyou being 54.95% and 74.10%, respectively. Contrasted with control, those were improved by 120.24% and 127.30%, respectively. Coating treatment (A, B) improved the survival rate of seedlings after low temperature treatment at the bud stage, and coated after soaking treatment (B) improved the survival rate of seedlings after low temperature treatment at the two-leaf stage.
