摘要/Abstract

摘要：

水稻作为重要的禾谷类作物之一,如何提高其产量一直备受人们关注。随着直播技术在亚洲一些国家和地区的广泛应用,水稻种子活力这一农艺性状显得尤为重要。本文对种子的发育和萌发过程和种子活力的概念加以说明,同时分析了水稻种子活力的影响因素、生理生化机制和遗传机理,介绍了水稻种子活力QTL/基因定位的研究进展并提出了展望,对指导以改良种子活力为目标的作物育种具有重要意义。

关键词: 水稻, 种子活力, 生理生化机制, QTL定位, 基因定位

Abstract:

It has always been one of common concerns to improve grain yield of rice, one of the most important cereal crops. Seed vigor has been an increasingly important agricultural trait as direct-seeded rice technology is widely applied in some Asian countries and regions. The concepts of seed development, germination and seed vigor were introduced. And the influencing factors of seed vigor, physiological and biochemical factors and genetic mechanism were analyzed. The research progress of QTL/gene mapping in rice seed vigor was introduced and the prospect was predicted, which is of great significance to crop breeding aiming to improve the seed vigor.

Key words: rice, seed vigor, physiological and biochemical mechanism, QTL mapping, gene mapping
