【摘要】 我国柚类主要有三大品种群:沙田柚、文旦柚和种间杂交品种群,其中以文旦柚品种群裂果最严重。裂果是一种生理病害,主要由遗传特性决定,但同时受果皮结构特征、矿质营养、激素和外界环境影响。裂果易腐烂,不易储运,进而降低果实的商品价值,产生巨大的经济损失。本文就裂果形态与时期、裂果影响因素和防裂技术措施等3方面进行综述,以期为文旦柚品种群果实裂果研究与栽培提供参考。更多还原

【Abstract】 There are three major cultivar groups of pome lo in China: Shatianyu, Wentan and interspecific hybrid, among which the cracking of Wentan pomelo cultivar groups is the most serious. Fruit cracking is a physiological disease, which is mainly determined by genetic characteristics, and is affected by the structural characteristics of the peel, mineral nutrients, phytohormones and the external environment. Cracked fruit is perishable and difficult to store and transport, which in turn reduces the commodity value of the fruit and generates huge economic losses. This article reviewed the three aspects of fruit cracking on morphology and time, factors and control measures to provide references for research and cultivation of fruit cracking of Wentan pomelo cultivar groups.更多还原
