Effects of Different Chemicals and Seed Coating Agents on Rice Seed Germination
摘要
Abstract
In order to screen the efficient seed soaking and regulating substances suitable for cold-region rice,Kenjing 8 was used as the test material.A single-factor randomized block design was adopted to investigate the effects of different concentrations of inositol-6-phosphate(IP6),putrescine(PUT),Linong seed coating agent,CS8,Bacillus laterosporus and gibberellin(GA3)on rice seed germination,vigor and seedling growth.The results showed that 0.15%IP6(I1)teeatment had the greatest effect on increasing the seed germination rate and vigor,with the 7-day germination rate increasing by 17.00%and the vigor increasing by 15.77%compared with the control(CK).The 6-fold diluted CS8(C2)teeatment had the best effect on promoting the germination rate and root length,with the germination rate increasing by 13.22%and the root length increasing by 30.49%compared with CK.GA3 had a significant promoting effect on the shoot length,with 3-9 mg·kg-1 GA3 increasing the shoot length by 50.55%to 67.58%,and 6 mg·kg-1 GA3 achieving the optimal levels of germination index,vigor index and seedling biomass.Overall,the effect of each reagent was to promote at low and medium concentrations and inhibit at high concentrations.The mold rate of IP6 increased significantly with increasing concentration,and high concentrations severely inhibited the germination of rice seeds.Bacillus laterosporus and seed coating agents had mild and safe effects.In conclusion,GA3 had the best overall regulatory effect on rice seed germination and seedling growth.关键词
