摘　　要：植物衰老在农业生产中产生巨大的影响,牧草提前衰老导致草地生产力下降,限制草产业的发展。深入揭示植物衰老特性和调控机制,不仅对于阐明植物生态适应性及种群稳定性具有重要价值,而且对于延缓衰老技术和调控措施的选择具有重要实践意义。植物衰老是一个相对复杂的过程,由内部遗传因子和外部环境共同决定。本文综述了植物衰老的概念、研究历史和植物衰老学说,重点论述了植物衰老的端粒学说,并总结了端粒在植物衰老中的研究进展,以为后续从端粒系统角度解析植物衰老机理提供理论参考依据。Plant senescence has a great impact on agricultural production.Premature senescence of crops leads to a decrease in yield,and premature senescence of forages leads to a decrease in grassland productivity,which limits the development of the grass industry.Deeply revealing the characteristics and regulatory mechanisms of plant senescence is not only of great value to clarify the ecological adaptability and population stability of plants but also of great practical significance to the selection of anti-aging technologies and regulatory measures.Plant senescence is a relatively complex process,which is determined by internal genetic factors and the external environment.This study summarizes the concept,research history,and plant senescence theory of plant senescence,focuses on the telomere theory of plant senescence,and summarizes the research progress of telomere in plant senescence,so as to provide a theoretical reference for the follow-up analysis of plant senescence mechanism from the perspective of telomere system.
