摘　　要：植物花器官会经历形成、发育、成熟到衰老的过程。维持花器官生理状况和营养水平可有效延长花期。植物花期既受到自身遗传因子作用,也受外界环境因子和人为调控的影响。花器官过早衰老不利于繁衍和景观效果的营造,抑制植物衰老进程、延长花期成为了愈来愈重要的科学问题。调控环境、人工修剪、添加植物生长调节剂、添加营养物质、品种搭配设计和基因工程等是有效延长花期的措施。本综述回顾了国内外基于以上措施对观花植物花期延长的研究进展和效果,为延长花期的研究和技术发展提供参考和指导。Plant flower organs undergo various processes,ranging from formation to development,maturity,and senescence.Maintaining the physiological conditions and nutrient levels of flower organs can effectively prolong the flowering period.The flowering period of plants is influenced by both genetic and environmental factors.Premature senescence of flower organs is not conducive to reproduction or the creation of landscape effects.The ability to restrain the senescence process of plants and prolong the flowering period has become an increasingly important scientific problem.Environmental regulation,artificial pruning,adding plant growth regulators,adding nutrients,variety matching designations,as well as genetic engineering are effective measures for prolonging the flowering period.This paper reviews the progress and effect of the research on prolonging the flowering period based on the above measures to provide a reference and guidance for the research and development of techniques for inhibiting senescence and prolonging the flowering period.
