摘　　要：芽苗期低温冷害是影响玉米分布和稳产高产的制约因素之一,如何通过栽培技术措施提高玉米的抗寒性是玉米生产过程中亟待解决的问题。本研究综述了芽苗期低温对玉米生长形态和生理生化的影响,并对相关的抗逆栽培措施进行了介绍和评价,以期为抗低温栽培提供可行的思路。Chilling at germination and seedling stage is one of restrictive factor for maize distribution and achieving high yield.Improving of chilling tolerance through cultivation technique measures played important roles in maize production.In this paper,we reviewed effects of chilling at germination and seedling stage on maize growth and internal physiology processes.Several management strategies to alleviate chilling stress were also proposed and evaluated in order to provide feasible regimes for chilling tolerance cultivation.
