- 摘要:
- 作为早花树种，樱桃在春季气温波动期间即进入开花期，其生殖生长阶段极易遭受低温伤害。这种非生物胁迫不仅会造成花器官冻害、授粉障碍等生理损伤，更会显著降低坐果率，最终影响果实产量与品质。该文阐述了樱桃花期低温胁迫生理机制的最新研究进展，重点探讨了不同栽培品种的低温敏感性差异，从细胞膜透性、渗透调节物质积累、活性氧清除系统等生理生化指标的变化规律展开分析，并深入阐释了低温响应基因的表达特征及其调控网络，以期为樱桃抗寒育种及栽培技术创新提供参考依据。
- Abstract:
- As a tree species that blooms early,cherry is highly vulnerable to low-temperature damage during its reproductive growth phase,which coincides with volatile spring temperatures.This abiotic stress induced physiological harm,including freeze damage to floral organs and impaired pollination,and significantly lowers fruit set,consequently diminishing both fruit yield and quality.This review presented the latest advancements in understanding the physiological mechanisms of cherry′s response to low-temperature stress during flowering.It placed a special emphasis on varietational differences in cold sensitivity and analyzed the dynamic changes in physiological and biochemical markers,included cell membrane permeability,the accumulation of osmolytes,and the reactive oxygen species (ROS) detoxification system.Additionally,the study offered a detailed elucidation of the expression profiles of low-temperature-responsive genes and their regulatory networks,intending to furnish a theoretical framework and practical guidance for the development of cold-hardy cherry cultivars and innovative cultivation practices.
