摘要
【目的】更好地对江西省境内野生毛花猕猴桃(Actinidia eriantha Benth.)资源进行评价。【方法】对野生毛花猕猴桃118份资源果实的主要数量性状进行统计分析和分级。果实的主要数量性状包括单果质量、果形指数、干物质含量、维生素C、可溶性固形物(SSC)、可溶性糖及可滴定酸7项指标,根据K-S正态性检验及频率分布对数量性状进行分级。【结果】单果质量变异系数最大,为33.65%;可溶性固形物最小,为11.91%。经K-S正态性检验,大部分性状呈偏正态分布;根据分析结果,提出5级数量性状分级标准,每个等级提出2份不同区域种质作为参照。【结论】该研究可为我国毛花猕猴桃资源描述的规范化、标准化提供参考。
【Objective】There is a special germplasm resource in China,called wild Mao Hua kiwifruit（Actinidia eriantha）,which currently has a high utilization value. The main grading standard used for kiwi-fruit is DUS（distinctness,uniformity and stability） testing standards（Actinidia） which were released bythe Agricultural Ministry of China. These standards are used primarily on A. chinensis and A. deliciosa which are the current commercial varieties of kiwifruit. In this study,the main quantitative characteristicsof wild A. eriantha in Jiangxi province are discussed,along with references to the germplasm resourceswhich are proposed. This research could provide references for the specification and data standardizationof kiwifruit germplasm descriptor systems.【Methods】In this research,118 tested materials were obtainedfrom a previous positioning observation site： the Magu mountain nature protection area of Nancheng coun-ty in Jiangxi province（N27° 31′46′′,E116° 32′52′′ to N27° 32′00′′,E116° 32′16′′）,where there arethree scattered distribution areas which have a similar habitat surrounding them. The testing took placeduring September to December 2013 and 2014. Testing consisted of performing a germplasm resourcescensus,making the choice and location of the site of the wild A. eriantha during the first year,then posi-tioning,observing and recording the details in the second year. Tested materials were harvested by stages（1st to 10 th in November）,the requirement standard for harvesting was when the fruit soluble solids con-tent reached 6.0%. After fruit post-ripening and softening in the laboratory under normal room tempera-ture,all the quantitative character indexes were tested and evaluated when the condition of the fruit wasedible（pulp hardness up to 1.0 kg·cm-2）. The average fruit mass was determined by using an electronic balance,the fruit shape index by using the vernier calipers measurement（including the longitudinal diam-eter of the fruit＇s longest part
