Problems solved by technology

However, eugenol is not water soluble, so an emulsifier needs to be added when using it; nevertheless, it is still extremely inconvenient to use

Embodiment 1

[0031] 1. Effects of different concentrations of glucosamine on rice seed germination

[0032] Use the chemical agent glucosamine with a concentration of 0, 100, 200, 300, 400, 500, 600, 700, 750, 800, 850, 1000mmol / L, and prepare them in aqueous solution, and add 0.02% (v / v) TWEEN20 at the same time .

[0033] Soak mature rice seeds (Nipponbare) in the above solution for 3-5 seconds, take them out, and dry them on tinfoil; then place them on moist filter paper, germinate at a constant temperature of 28°C, and count the germination rate every other day. The germination standard is that the germ or radicle grows 1mm and is germination.

[0034] The results show (Table 1), glucosamine above 100mmol / L can effectively delay the germination rate of seeds, compared with glucosamine lower than 700mmol / L, higher concentration of glucosamine (700-850mmol / L) delays the rate of seed germination. The effect of germination is more obvious, but when the concentration of glucosamine reache...

Embodiment 2

[0037]Example 2 Effects of Different Concentrations of Glucosamine on Ear Germination of Hybrid Rice

[0038] For the preparation of the panicle germination inhibitor, according to the results in Example 1, 3 concentrations of glucosamine aqueous solutions were prepared, namely 700, 750 and 850 mmol / L. In the indica rice hybrid Qian 6 You 688 seeding field, when the hybrid grows to the yellow maturity stage, the hybrid rice ear is collected, sprayed with the above-mentioned ear germination inhibitor to a saturated state, and dried in the shade on tin foil at room temperature for 24 hours, and then the whole rice ear is placed in a humid On the filter paper, spray water every 2-3 hours to a saturated state, germinate at a constant temperature of 28°C, and count the germination rate every 1 day. The germination standard is that the germ or radicle grows 1mm and is germination.

[0039] The results showed that the ear germination inhibitor glucosamine obviously delayed the ear g...

Embodiment 3

[0042] The impact of the copper sulfate aqueous solution of embodiment 3 different concentrations on rice seed germination

[0043] The present invention also studies the influence of using copper sulfate aqueous solution alone on the germination of rice seeds. The copper sulfate aqueous solution was used at a concentration of 0, 10, 20, 25, 30 and 35 mmol / L, and 0.02% (v / v) TWEEN20 was added at the same time. Soak mature rice seeds (Nipponbare) in the above solution for 3-5 seconds, take them out, and dry them in the shade on tinfoil. Then put it on wet filter paper, germinate at a constant temperature of 28°C, and count the germination rate every other day. The germination standard is that the germ or radicle grows 1mm and is germination. The result shows (table 2), and the copper sulfate solution above 25mmol / L has obvious inhibitory effect to rice seed germination, and the copper sulfate solution of 18-22mmol / L then obviously has the effect of delaying seed germination. ...

Abstract

The invention discloses an application of glucosamine as a preharvest sprouting inhibitor in inhibition of preharvest sprouting of hybrid rice. Mature seeds are soaked in a glucosamine solution, it is found that glucosamine can effectively delay the germination rate of the seeds, an appropriate inhibitor concentration is found through a preharvest sprouting inhibition test, and new application of glucosamine as a preharvest sprouting inhibitor of hybrid rice is disclosed. The invention further provides a preharvest sprouting inhibitor with effective inhibition concentration. And the glucosamine and the copper sulfate are compounded for use, so that the germination rate of the seeds is further effectively delayed, the use amount of the glucosamine is reduced, the raw material cost is effectively reduced, and the method is convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of hybrid rice seed production, in particular to the application of glucosamine as a panicle germination inhibitor in inhibiting hybrid rice panicle germination. Background technique [0002] Seeds of cereal crops such as rice often germinate on the panicles when they encounter continuous rainy, low-sun, high-temperature and high-humidity weather during the maturity period, which is called panicle germination, also known as pre-harvest sprouting (PHS). [0003] The ear germination process not only affects the degradation of starch and protein in rice storage, but also affects the storage of rice and the seed value of hybrids (Hu Weimin et al. Germination characteristics on the panicle of male sterile lines in hybrid rice seed production. Acta Crops, 2003, 29: 441- 446; Ma Liangyong et al. Effect of ear germination of early rice on rice yield and rice quality. China Rice, 2004, 10: 15-16). Affected by natura...
