不同套袋时间对早香橘橙果实色泽的影响

Effects of Different Bagging Time on the Color and Luster in Zaoxiang Mandarin Fruit

对三次不同套袋时间对早香橘橙果实色泽的影响进行了分析研究。结果显示,套袋时间早、遮光性强的果袋对果实果皮色泽亮度、色饱和度的影响大于遮光性弱的或晚套袋的处理。果实色泽平均a/b值10月4日套袋好于7月14日,8月30日套袋处理,果实色泽更加的接近早香橘橙果实所固有色泽:橙黄色,但均小于对照(0.53)。套袋时间早果皮色泽色调角小于晚套袋处理,并且均大于对照(-10.23)。经相关系数分析,a/b与色调角呈极显著负相关,相关系数为:-0.9574。不同套袋时间、不同遮光率的果袋对早香橘橙果实色泽有不同的影响。

The effects of three different bagging times on the color and luster in zaoxiang mandarin fruit were studied and analyzed. The results indicated that the effects of the brightness,saturation on the earlier bagging time, strong light penetration bag were better than the weak light penetration or later bagging time treatment. The average ratio of a/b on the 4,Oct was better than on the 14,Jul and the 30, Aug, but three ratios of a/b were lower than the control treatment （0.53）,so the color in the zaoxiang mandarin fruit was close to native color , orange-yellow color. The tone-angle on the earlier bagging time was lower than the later bagging time, but three tone-angles were bigger than the control treatment （-10.23）. The significant negative coefficient of the ratio of a/b to the tone-angle is -0.9586＊＊ by correlation analysis; The different effects on the color and luster in zaoxiang mandarin fruit would change as a result of different bagging times and kinds paper bags.
