| 柑橘生产中几乎所有品种在果实成熟期都出现陷痕果现象，已成为商业种植中非常严重的问题。本研究于2007年和2008年调查了不同柑橘品种的陷痕果发生率，包括广东省龙门县、廉江市、增城市的红江橙，江西省安远县、寻乌县、广东省中山市的华盛顿脐橙、朋娜脐橙、纽荷尔脐橙、奈维林娜脐橙和卡拉卡拉脐橙，结果表明：不同品种的陷痕果率差异显著，但是不同柑橘品种在不同年份的陷痕果率无显著性差异，奈维林娜脐橙、卡拉卡拉脐橙、华盛顿脐橙、红江橙是高陷痕果率品种，纽荷尔脐橙是低陷痕果率品种。山地种植的砂糖橘陷痕果率显著大于水田的陷痕果率，树冠外围的陷痕果发生比例显著小于树冠内膛的陷痕果率。随着树龄的增长纽荷尔脐橙的陷痕果率也增加。 |

| Abstract: Citrus pitting is a serious pre-harvest physiological disorder commonly found in many citrus orchards and results in lots of loss in commercial cultivation. Different citrus species were used in this study, including ‘Hong Jiang’ (grafting chimaera of Citrus sinensis Osbeck and Citrus reticulata) Washington（Citrus sinensis Osbeck cv. Washington）, Bonanza（Citrus sinensis Osbeck cv. Skaggs Bonanza）, Newhall（Citrus sinensis Osbeck cv. Newhall）, Navelina（Citrus sinensis Osbeck cv. Navelina）, and Caracara navel orange（Citrus sinensis Osbeck cv. Cara Cara）. ‘Hong Jiang’ was planted in Longmen county, Zengcheng and Lianjiang city of Guangdong province, the others were produced in Anyuan and Xunwu county of Jiangxi province and Zhongshan city of Guangdong province. The results showed the occurrence of the pitting fruit varied in various species. The significant difference exist in the different species which were planted in the same citrus orchard, and Navelina, Calacala, Washington navel orange and ‘Hong Jiang’ sweet orange were high pitting fruit rate cultivars, Newhall navel orange was a low pitting fruit rate cultivar. The fruit which was from inner crown was easier to fruit pitting than that from in outer crown, the fruit rate of shaded peel was higher than that of exposed peel, and the pitting fruit rate of tree which was planted on mountain than on inner crown was higher than which was planted on paddy field in Shatangju orchard. The pitting fruit rate of eight-years old Newhall navel orange is higher than five-year old Newhall navel orange orchard. |
