Advances in the Influencing Factors and Mechanism of the Flower Bud Differentiation of Camellia oleifera
摘要
Abstract
Camellia oleifera seed oil,rich in unsaturated fatty acids and other nutrients,has been recommended by the Food and Agriculture Organization of the United Nations as the best healthy edible plant oil.However,the large number of flowers but extremely low natural fruit setting rate of C.oleifera,as well as the alternate bearing phenomenon,have led to low economic benefits,seriously restricting the healthy de-velopment industry.Relevant studies have found that these problems may be related to the site environment of C.oleifera forests and the nutri-tional status of the trees,especially the quality of flower bud differentiation has a significant impact on fruit yield.The process of flower bud differentiation of C.oleifera is affected by the comprehensive effect of many internal and external factors,and its physiological and molecular regulatory mechanism is quite complex,and how to regulate the differentiation of flower buds is an urgent problem to be solved in the C.oleif-era industry.This paper reviewed the physiological stages and particularities of C.oleifera flower bud differentiation and the factors affecting the bud differentiation of C.oleifera based on domestic and foreign research,including the level of endogenous hormones,the accumulation of carbohydrates,the supply of various mineral elements and other nutritional status,and environmental factors such as light,temperature and moisture.The molecular physiological mechanism of the role of various factors in the bud differentiation of C.oleifera was proposed,and the mechanism of endogenous hormones and nutrients in spring shoots on the differentiation of C.oleifera flower buds was strengthened,and the dynamic changes of nutrients and endogenous hormones in flower buds during the flower bud differentiation period were analyzed,and the in-ternal relationship between these changes and the process of flower bud differentiation was clarified.Based on the above results,this article points out that flower bud differentiation in C.oleifera has particularities and requires artificial regulation to promote fruiting and achieve high and stable yields.This article provides a research direction for promoting high and stable yields of C.oleifera and promoting the healthy devel-opment of the C.oleifera industry,which has important theoretical and practical significance.关键词
