采后柑橘生理病害与果皮超微结构变化的关系

摘要

采后柑橘果实在贮藏过程中,在不适的环境因子作用下,导致果实生理代谢发生障碍,从而产生了生理性病害,如冷害、油胞病、褐斑病以及水肿病等,在一定程度上降低了果实的感官品质和耐贮性,进而影响果实的食用品质。本文从柑橘主要生理病害与果皮细胞膜、细胞壁和亚细胞结构变化的关系着手,对采后柑橘果实几种常见生理性病害发生过程中果皮超微结构的变化进行了综述,旨在为采后柑橘果实生理病害发病机理的深入研究提供参考。%Due to inappropriate environmental factors causing physiological metabolism disorders,post-harvest citrus fruits during storage can produce a number of physiological disorders including chilling injury,oleocellosis,rind pitting and edema.These physiological disorders can reduce the sensory quality,storability and edible quality of fruits.In this paper,the relationships between major physiological disorders of citrus peel and the changes of cell membrane,cell wall and subcellular structures are reviewed.Meanwhile,the ultra-structural changes of citrus peel during the occurrence of these physiological disorders are discussed for the purpose of providing a theoretical basis for exploring the mechanisms and control methods of physiological disorders in citrus fruits.
