摘要:

早稻是我国南方地区重要的粮食作物之一,其产量的稳定对保障粮食安全具有重要意义。然而,全球气候变化的不断加剧,使得极端天气事件愈发频繁,给早稻生产带来了前所未有的挑战。在早稻的生长周期中,前期低温寡照常导致种子萌发受阻、幼苗生长迟缓、分蘖数量减少以及成穗率下降,严重制约早稻的产量。本文综述了前期低温寡照对早稻生长发育、生理代谢和相关抗逆基因表达的影响,探讨了耐前期低温寡照的早稻品种评价指标,总结了提高早稻耐低温寡照的栽培调控技术,并对今后的研究方向提出了建议。

Abstract:

Early rice is one of the important food crops in the southern China, and the stability of its yield is of great significance for ensuring food security. However, the intensifying global climate change has led to an increasing frequency of extreme weather events, posing unprecedented challenges to early rice production. During the growth cycle of early rice, low temperature and insufficient light in the early stage often result in impeded seed germination, retarded seedling growth, decreased tillering, and reduced heading rates, severely constraining early rice yields. This paper reviewed the effects of low-temperature and insufficient light in the early stage on the growth, physiological metabolism, and expression of related stress resistance gene in early rice. It also discussed the evaluation indicators for early rice varieties resistant to low temperature and insufficient light, summarized cultivation and regulation techniques to enhance early rice’s tolerance to low temperatures and insufficient sunlight, and put forward suggestions for future research directions.

Key words: early rice, low temperature and insufficient light, physiological trait, cultivation control techniques
