摘　　要：作物早发是指在多种环境下种子快速一致的发芽和良好健壮的苗期建成。早发不仅有利于作物对光照、养分、水等资源的有效利用,还有利于增强其与杂草的竞争能力,促进叶面积发育,提高作物生长速率和发育速率,增加干物质积累,提高产量。本文总结了作物早发的概念及评价指标、早发的鉴定及其机制、早发的作用以及促进早发的措施,以期为早发品种的培育和栽培提供理论基础。Crop early vigor is the characteristic of seed quality with the rapid,uniform germination and the establishment of strong seedings under various environmental conditions.Early vigor is critical to improve crop seedlings’access to light,nutrients and water resources,weed competitiveness,leaf area development,crop growth and development rate,dry matter accumulation and yield.This article summarized the concept and evaluation index of early vigor,genetic mechanisms of early vigor,role of early vigor,and measures to improve early vigor,which can provide a theoretic basis for the breeding and cultivation of early vigor crop varieties.
