随着果实的发育、成熟和衰老,华盛顿脐橙果实表皮的蜡质数量和结构也在相应地发生变化,导致与其相关的一些生理生化反应,从而影响挂果时间、贮藏时间和果实的商品价值。本文旨在研究(1)整个果实生长、发育、成熟和衰老过程中果实表皮蜡质的数量及其超微结构的变化;(2)GA_3和2,4—D对果皮年龄及品质有关的这些参数的影响。所用材料都来自加州96株14年生枳橙砧华盛顿脐橙。对全树进行三种处理;喷洒10ppm的GA_3;16ppm的2,4—D;10ppm的GA_3十16ppm的2,4—D。对照不
With the development, ripening and senescence of fruit, the amount and structure of wax in the cuticle of Washington Navel orange fruit also change correspondingly, leading to some physiological and biochemical reactions related to it, which will affect the fruiting time, the storage time and the commodity value of fruit. The purpose of this paper is to study (1) changes in the amount and ultrastructure of epidermal wax in the fruit during growth, development, maturation and senescence; (2) the effects of GA 3 and 2,4-D on the peel age and quality Effect of parameters. The materials used were from California 14 strains of 14-year-old orange citrus arizona orange. Three treatments were performed on the whole tree; spraying 10 ppm of GA_3; 16 ppm of 2,4-D; 10 ppm of GA_3 and 16 ppm of 2,4-D. Control not
