摘要
花芽分化是葡萄生长发育过程中十分重要的阶段,而葡萄的成花过程较特殊,成花诱导更复杂,表现在始原基分化后能进一步分化形成花序,也能分化成卷须发育成为营养器官。葡萄花芽分化过程受诸多内部和外部因素影响,生理及分子调控机制复杂。文章结合国内外研究综述葡萄花芽分化的生理阶段及其特殊性,成花诱导和花形态建成相关基因功能及表达,以及影响葡萄花芽分化的因素,包括环境因素(温度、光照和水分)、树体营养(碳水化合物和矿质元素)、内源激素水平和栽培技术等。根据葡萄花芽分化方面需进一步研究的问题,提出完善不同葡萄品种花芽分化进程、结构特性及冬芽次年花器官分化阶段等形态结构方面的研究,利用多组学关联分析深入探究葡萄花芽分化分子调控机制,以及开展不同栽培模式下葡萄花芽分化规律研究,进而推进葡萄花芽分化生理及分子机理的系统研究,为葡萄生产调控提供理论参考。
Flower bud differentiation of grape is a very important stage in its growth and development.Flowering pro-cess of grapes is relatively different,and its flower induction is more complex.After differentiation,primordium can fur-ther develop into inflorescence or into tendril to be a vegetable organ.The process of flower bud differentiation is affected by many internal and external factors.Its physiological and molecular regulation mechanism is complex.In this paper,the physiological stage and the particularity of grape flower bud differentiation,the function and expression of genes related to flower induction and flower morphogenesis,and the factors affecting flower bud differentiation such as environmental factors(temperature,light,and water),tree nutrition(carbohydrates and mineral elements),endogenous hormone levels,and cultivation techniques were reviewed based on domestic and foreign studies.For the issues of grape flower bud differen-tiation require further study,researches in respect of morphogenesis and strcuture were carried out to improve flower bud differentiation process and structure characteristics of different grape varieties and flower organ differentiation stage of winter bud in the next year.The molecular regulation mechanism of grape flower bud differentiation was studied by multi-omics association analysis,and the research on the regulation of grape flower bud differentiation under different cultiva-tion modes was carried out,so as to promote the systematic research on the physiological and molecular mechanism of grape flower bud differentiation,which would provide a theoretical reference for the regulation of grape production.
