摘要: 植物矮化是一种重要的农艺学性状,是生命科学领域研究的重要内容之一,矮化研究是植物育种工作的热点。矮化来源分为诱变矮化和自发矮化,其中诱变矮化中的物理诱变研究的内容分类详细,在航天诱变领域取得了有效的研究成果。植物矮化机理的研究主要集中于植物内源激素,主要是赤霉素、油菜素内酯,也有少量关于生长素的研究。针对不同种类植物具体详细的矮化机理,还没有明确的分类和细化的研究。总结了植物矮化突变体的来源及矮化机理。

关键词: 矮化突变体, 矮化来源, 矮化机理

Abstract: Dwarf is one of essential agronomic features and the important research field in life science as well as the hot area in plant breeding. Based on dwarf origins, dwarf can be divided into mutated dwarf and spontaneous dwarf. The mutated dwarf includes physical mutation,  chemical mutation and  biological mutation. Much more researches about physical mutation have been done, especially in space mutation area. The study of dwarf mechanism mainly focused on plant endogenous hormone, including gibberellins,  brassinolides and auxins etc. Regarding the concrete dwarf mechanism of different plants, no clear classification and detailed researches are available now. This paper summarized the origins of dwarf mutant and their dwarf mechanisms, the dwarf origins and mechanism of the dwarfish plants mutant.

Key words: Dwarf mutant, Dwarf origins, Dwarf mechanism
