早稻前期低温寡照对生长发育的影响及调控技术
Effects of Low Temperature and Insufficient Light during the Early Stage of Early Rice on Growth and Development and its Regulatory Techniques
摘要
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.关键词
