摘要: 温度是影响小麦生长发育和产量品质形成的重要因素之一,而温度逆境胁迫对小麦粒重 的影响与胁迫发生时期、胁迫强度、胁迫持续时间以及小麦品种抗性紧密相关。源、库、流是决定 小麦产量的重要因素,温度逆境胁迫通过影响小麦源、库、流器官的运作,导致“源-库”失调,最 终降低粒重。要提高小麦产量,必须强“源”、扩“库”、畅“流”。综述了温度逆境胁迫下小麦粒重 形成的调控机制,主要包括温度逆境对小麦源、库、流等器官的影响,并从品种、播期播量、水肥运 筹和化学调控剂等方面分析了不同栽培措施对小麦抗温度逆境的调控效应,以期为小麦生产的 防灾减灾和可持续高质量发展提供理论支撑。

Abstract: Temperature is one of the most important factors affecting the growth and development of wheat and the formation of yield quality. The effect of temperature stress on wheat grain weight is closely related to the stress occurrence period,stress intensity,stress duration, and wheat variety resistance. Source, sink, and flow are important factors determining wheat yield. Temperature stress affects the functioning of the source,sink,and flow organs of wheat,resulting in a dysregulation of the ″ source-sink″ and ultimately a reduction in grain weight. To improve wheat yield ,it is necessary to strengthen the ″source″,expand the ″sink″,and smooth the ″flow″. This research reviewed the regulatory mechanisms of wheat grain weight formation under temperature adversity stress,mainly including the effects of temperature adversity on wheat's source,sink,and flow organs. The regulation effect of different cultivation measures on wheat resistance to temperature stress was analyzed from the aspects of variety,sowing date and density,water and fertilizer operation, and chemical regulators, which provided theoretical support for disaster prevention and reduction and sustainable high-quality development of wheat production.

Key words: temperature, stress of adversity, wheat, grain weight, source-sink relationship
