摘要
辣椒(Capsicum annuum L.)作物经济价值高、种植广泛,我国大多数辣椒栽培品种株型较高、分枝多、易倒伏、不利于机械化生产,人工生产成本不断上涨。随着农业生产技术水平的提高,劳动力日益紧缺,传统农业向现代机械化农业的转变迫在眉睫。作物理想株型的提出让植物株型调控成为遗传育种中的热点,可为辣椒株型调控机制的解析提供借鉴。本文围绕近年来国内外学者对植物株型调控遗传因素、分子机制、植物激素与株型的生物学关联方面和环境对株型的影响取得的研究成果进行综述,并提出了辣椒理想株型的设想。良好的辣椒株型能提高植株生产能力,便于管理,缓解劳动力紧缺,加速机械化生产进程。目前,关于辣椒株型调控机制的研究报道很少,因此探讨植物株型调控育种机制和遗传基础,有利于为良好株型种质资源的创制和加快新品种选育提供理论支持,为遗传育种奠定基础。
Chili(Capsicum annuum L.)crops have high economic value and extensive planting,and most of the chili cultivars in China have high plant type,many branches,easy lodging,not conducive to mechanized production,and the cost of artificial production is rising.With the improvement of agricultural production technology and the increasing shortage of labor,the transformation of traditional agriculture to modern mechanized agriculture is imminent.The proposal of ideal plant type makes plant type regulation a hot spot in genetic breeding,which can provide reference for the analysis of the regulation mechanism of chili plant type.This paper reviews the research results of recent domestic and foreign scholars on the genetic factors and molecular mechanisms of plant type regulation,the biological relationship between plant hormones and plant type,and the influence of the environment on plant type,and puts forward the idea of ideal plant type of chili.Good chili plant type can improve plant production capacity,facilitate management,alleviate labor shortage,and accelerate the process of mechanized production.At present,there are few research reports on the regulation mechanism of chili plant type,so exploring the breeding mechanism and genetic basis of plant type regulation is conducive to providing theoretical support for the creation of good plant type germplasm resources and accelerating the selection and breeding of new varieties,and laying the foundation for the genetic breeding.
