【摘要】 <正> 柑桔果实贮藏运输过程中,发生汁胞逐渐失水粒化,同时囊瓣与果皮分离,果皮发泡,油胞凸出,外观似极新鲜,重者整个果皮呈凹凸不平状,称之为枯水。 枯水是宽皮桔延长贮藏期的限制因素,在甜橙贮藏中,某些年份为害严重;对“早熟柚”和一些“红心柚”品种,也是限制贮藏的因素。更多还原

【Abstract】 Several physiological and Chemical Changes in The rind and juice sac of typical samples of normal, incipiently granulated, half granulated and entirely granulated fruits of Pioneer orange (C. sinensis O.)and Satsuma orange (C. unshiu M.)fraits were studied for two years(1977,1978).With the development of granulation and rapid reduction of fruit juice, the percentage of total sugar content and dry matter of rind and juice sac both decreased correspondingly. But contrary to the visible phenomenon to the naked eyes, the water content of rind and juice sac of the entirely granulated fruit both increased significantly, and the respiratory intensity turned upward.Morever, the rind became thick and the percentage in weight of rind markedly increased, but the dry weight of rind per 100 g fresh fruit of the entirely granulated fruit was even heavier than that of the normal ones. These results indicated that in the course of development of granulation, sharp physiological losses occared in the citrus fruits, and there might exist the trend and possibility that the nutritive materials is shifted from juice sac to the rind.The dramatical increase of pure cellulose content in juice sac of entirely granulated fruits, showed senescence might take place in the tissue of juice sac in the process of granulation.更多还原
