在国外,植物激素主要用在果树、蔬菜和林木上,在禾谷类作物、特别是水稻上应用得很少。在我国,水稻上使用激素已取得较大的成绩,尤其在杂交水稻制种上,使用激素已成为夺取高产必不可少的一种手段。周广洽等认为,植物激素对调节杂交水稻库(Sink)、源(Source)关系有一定的作用。 Abroad, plant hormones are mainly used on fruit trees, vegetables and trees, and are rarely used on cereal crops, especially rice. In our country, the use of hormones on rice has made great achievements. Especially in hybrid rice seed production, the use of hormones has become an indispensable means of obtaining high yields. Zhou Guangqia et al. Conclude that plant hormones play a role in regulating the relationship between Sink and Source.
