【 摘 要 】

The relationship between the metabolites in the seeds and the emergence and establishment of the seedlings were investigated in container experiments to improve the emergence and establishment of rice seedlings in direct seeded in flooded paddy field. The plant length, the leaf age and the dry weight of vegetative parts at 14 days after seeding were highly and positively correlated with the emergence rate at 14 days after seeding. Early emergence of seedlings increased the final emergence rate, and promoted the growth of aerial parts.
