以纽荷尔脐橙为试材,分析了湖北省13个产地果实的常规品质和果皮色差值,结果显示,不同产地纽荷尔脐橙果实品质差异明显。系统聚类结果表明,秭归县、巴东县和兴山县的常规品质聚为第一类,长阳县、郧县、公安县、枝江市和宜都市聚为第二类,而丹江口市、阳新县、通城县、天门市和京山县聚为第三类;就果皮色差值来看,长阳县、郧县、兴山县和宜都市聚为第一类,巴东县、京山县、枝江市、丹江口市、阳新县、公安县、秭归县聚为第二类,天门市和通城县聚为第三类。综合分析常规品质和果皮色差值可以看出,三峡库区的兴山县、秭归县、巴东县纽荷尔脐橙综合品质最好,邻近三峡库区的长阳县、宜都市、枝江市,丹江库区的郧县和卷桥库区的公安县次之,丹江口市、阳新县、京山县,尤其是天门市和通城县的品质表现不如上述各个产地。因此湖北省纽荷尔脐橙应重点集中在三峡库区这一优势区域内优先发展,同时向其邻近的适宜地区辐射,而在其它产地宜选择小气候适宜地区适当发展。
Newhall navel orange was used as experimental material to analyze the regular quality of fruit and peel color difference in 13 producing areas in Hubei Province. The results showed that the fruit quality of Newhall navel orange in different areas was significantly different. The results of cluster analysis showed that the conventional quality of Zigui County, Badong County and Xingshan County clustered in the first category, with Changyang County, Yunxian County, Gong’an County, Zhijiang City and Yidu City as the second category, while the Danjiangkou City, Yangxian County, Tongcheng County, Tianmen City and Jingshan County are the third group. In terms of pericarp color, Changyang County, Yunxian County, Xingshan County and Yidu City are clustered into the first category, Badong County, Jingshan County , Zhijiang City, Danjiangkou City, Yangxin County, Gong’an County and Zigui County clustered in the second category, and Tianmen and Tongcheng County clustered in the third category. Comprehensive analysis of conventional quality and peel color difference can be seen in the Three Gorges reservoir area Xingshan County, Zigui County, Badong County Newhall navel orange best overall quality, adjacent to the Three Gorges reservoir area of Changyang County, Yidu City, Zhijiang City , Yun County in Danjiang reservoir area and Gong’an County in Juanqiao reservoir area, Danjiangkou City, Yangxin County, Jingshan County, especially Tianmen and Tongcheng County, did not perform as well as the above-mentioned areas. Therefore, Newhall navel orange in Hubei Province should focus on the priority development within the Three Gorges reservoir area, and at the same time, should radiate to its suitable nearby area, while appropriate development should be selected in other suitable areas for microclimate.
