近年,为生产水稻、小麦等重要谷类的杂交种子,广泛使用化学杂交剂作为有效手段已十分引人注目。化学杂交剂已被用于生产,中国已有杂交水稻种子销售,美国也有杂交小麦种子销售。本文以水稻为主的重要谷物为对象,对化学杂交剂研究的历史、现状及今后课题予以介绍。一、什么叫化学杂交剂所谓化学杂交剂就是指该药剂能阻碍植株花粉发育的功能,抑制自花授粉,从而通过异花授粉获取植物的杂交种子的药剂。它作为植物生长调节剂的一类,可以称为杀雄剂或除
In recent years, the widespread use of chemical hybridizers as an effective means of producing hybrid seeds for important cereals such as rice and wheat has drawn considerable attention. Chemical hybridizers have been used in the production of hybrid rice seeds for sale in China and hybrid wheat seeds for sale in the United States. In this paper, the main grain-based rice as the object, the history of chemical hybridization research, the status quo and future topics to be introduced. First, what is the chemical hybridizing agent The so-called chemical hybridizing agent refers to the agent can hinder the plant pollen development function, inhibition of self-pollination, and thus by cross-pollination of plant hybrid seed medicine. It acts as a class of plant growth regulators that can be called a killing agent or in addition to
