杂交及不育系种子的穗上发芽问题长期来一直困扰着种子部门,各地都为此做过大量的试验和探索。本公司也曾在10年前与有关科研单位协作为解决穗上发芽问题用4年时间,做了大量试验,筛选控制穗上发芽的化学药剂,但真正能在生产应用又确有实效的药剂未曾发现,结果也是无功而返。到目前为止还尚未能完全解决这一问题。引发穗上发芽的原因是杂交、不育系种子在生产过程中, Sprouting on the spikes of hybrid and CMS lines has long plagued the seed sector, and numerous tests and explorations have been done in various parts of the country. The company also had 10 years ago with the relevant scientific research units to solve the ear sprouting problem with four years, a large number of tests, screening control of sprouting on the chemical agents, but really can produce practical and practical Pharmacy Did not find out, the result is no success. So far the problem has not been completely solved yet. Sprouting sprouting caused by hybridization, sterile seed in the production process,
