摘要
叶片早衰严重影响水稻产量与品质。研究水稻叶片早衰突变体的农艺及生理性状,有助于了解水稻叶片衰老进程和机理。本文简述了叶片衰老特征和衰老机制,重点综述了水稻叶片早衰突变体的类型、农艺与生理性状研究进展及延缓水稻叶片衰老的栽培调控途径。可为水稻抗衰老品种选育及栽培调控提供理论依据。
Early leaf senescence greatly affects grain yield and quality in rice. Studies on the agronomic and physiological traits of the early leaf senescence mutants in rice would be beneficial to understanding the senescence process and its underlying mechanism in plants. We briefly summarized the characteristics and mechanisms of early leaf senescence, with focus on reviewing the agronomic and physiological traits of early leaf senescence mutants in rice and the regulation ways of delaying leaf senescence. Such a review would lay a theoretical basis for the breeding of anti-aging varieties and optimized cultivation practice in rice.
