摘要/Abstract

摘要：

柑橘通常被认为是典型的非呼吸跃变型果实，脱落酸与果实成熟关系最大，但乙烯、赤霉素、生长素等激素也在柑橘成熟和转色中发挥重要作用。生产上，一些天然激素和人工合成的植物生长调节剂已经被广泛应用于柑橘果实上市时期的调整和果实的采后保鲜等。本文中综述了上述植物激素在柑橘果实成熟中的作用、激素间的互作、以及相关转录因子的调控机制等方面的研究进展，以期为进一步研究提供参考。

Abstract:

Citrus is usually considered as a typical non-climacteric fruit，with abscisic acid being primarily associated with citrus fruit maturity. However，other hormones，such as ethylene，gibberellin，auxin，also contribute significantly to the maturity and color transition of citrus. In production，a variety of natural hormones and synthetic plant growth regulators are commonly utilized to extend the marketing period of citrus fruits and improve postharvest preservation. This paper provides a comprehensive review of current research advances concerning the role of plant hormones on the maturation of citrus fruits. It delves into the complex relationships between these hormones and investigates the regulatory mechanisms controlled by related transcription factors. The primary aim is to provide reference for further research.

Key words: citurs, fruit maturation, hormones, regulatory, transcription factor
