旱育保姆包衣对不同萌发状态杂交稻种子出苗和幼苗生长的影响
Effects of Coating on Emergence of Hybrid Seed with Different Germination State and Seedling Growth
摘要
Abstract
[Objective]The study aimed to discuss effects of coating used in dry seedling bed on emergence of hybrid seed with different germination state and seedling growth. [Method] With three different kinds of grain type of hybrid rice seeds as materials, the coating was used in hybrid rice dry seedling bed after sowing and the seed had four germination state which is absorb-water grain, exposure-white grain, short-bud grain and long-bud grain, and the germination speed, emergence rate of seed and growth of seedlings were observe, taking no coating as contrast. [Result] The reaction of seeding emergence rate in different type and different seed germination state with coating has some differences. Whatever the grain type and germination state was, coating treatment can enhance the final emergence rate, especially for the slower germination speed of exposure-white and short-bud grain with short-round and crude-long grain type. Coating on seedling growth mainly reflected in plant height, it reduced the height and promoted root growth. [Conclusion]Treatment with coating promoted the grain germination of different grain types and different germination seeds, the effects are bound up with grain types and germination seeds. Rice treated with coating is easier to obtain strong seedlings.关键词
