摘要
为探明果用乌饭树的浆果性状及内含物种源变异,为优良果用乌饭树品种选育与遗传改良提供科学依据.在乌饭树浆果自然成熟季节,采集了福建、江西、浙江等地20个种源野生浆果进行表型性状与内含物测定分析.结果表明:1)不同种源乌饭树浆果表型直径存在显著差异,20个种源乌饭树浆果平均直径为5.67 mm,最大为8.07 mm,最小为3.27 mmo2)乌饭树浆果内含物主要为可溶性糖类、氨基酸、蛋白质、矿物质和维生素,其含量平均分别为156.12 mg/g、21.99 mg/g、8.45 mg/g、0.92 mg/g、0.78 mg/g,不同种源间差异显著,内含物中酸度平均为7.21 mg/g,呈现出随纬度的升高和内陆性的增强而增加的趋势.3)不同种源乌饭树浆果表型直径与可溶性糖类、蛋白质含量呈正相关关系,但与氨基酸、维生素含量及酸度呈负相关关系.研究结果为果用乌饭树的品种选育与遗传改良及深度开发利用提供了理论参考.
Abstract
In order to explore the berry traits and inherent species variation of Vaccinium bracteatum Thunb for?fruit?use,and provide scientific basis for the breeding and genetic improvement of excellent fruit use black rice varieties.During the natural ripening season of Vaccinium bracteatum Thunb,20 wild berries from different sources in Fujian,Jiangxi,Zhejiang,and other regions were collected for phenotypic traits and content analysis.The results showed that:(1)There were significant differences in the phenotypic diameter of blueberry berries from different provenances.The average diameter of blueberry berries from 20 provenances was 5.67mm,with the maximum being 8.07mm and the minimum being 3.27mm.(2)The inclusion contents of Vaccinium bracteatum Thunb berries are mainly soluble sugars,amino acids,proteins,minerals,and vitamins,with an average content of 156.12mg/g,21.99mg/g,8.45mg/g,0.92mg/g,and 0.78mg/g,respectively.There are significant differences among different sources,and the average acidity in the inclusion contents is 7.21 mg/g,showing an increasing trend with the increase of latitude and the enhancement of inland characteristics.(3)There is a positive correlation between the phenotypic diameter of blueberry berries from different sources and the content of soluble sugars and proteins,but a negative correlation with the content of amino acids,vitamins,and acidity.The research results provide a theoretical reference for the breeding,genetic improvement,and deep development and utilization of Vaccinium bracteatum Thunb for fruit use.
