摘要
以6份越南椰子资源、文椰3号和海南本地高种椰子为材料,对其果实品质相关的指标,如椰子单果重、果形指数、果实风味、可溶性固形物(TSS)等10个重要品质指标进行测定及分析。结果表明,不同资源的品质指标变化幅度较大,其中资源编号为1(YXS)和2(YTS)品质指标总体表现较好,可以作为椰子资源引进或重点培育的对象。经相关性分析可知,果实风味与TSS、果实风味与固酸比、TSS与固酸比、总糖与总糖/总酸比都呈极显著正相关(p<0.01),总糖/总酸比与固酸比呈显著正相关(p<0.05)。结合聚类分析,可将果实品质评价指标简化为单果重、果实风味或TSS、脂肪含量和固酸比4个主要指标,有助于越南椰子优良果实性状品种的评价和筛选。
Six Vietnamese coconut resources,Wen Ye No.3 （WY3） and Hainan BenDi Gao Zhong （HBG） were used as the experimental material.A total of 10 important quality traits of the fruit such as fruit weigh,indices of fruit shape,fruit flavor,total soluble solids （TSS） were measured and analyzed.The result showed that there was wide range of variance with quality traits on different resources,and the ＂Vietnamese coconut＂ resources No.1 （YXS） and 2 （YTS） were superior to others,which could be used as the two important ones for introducing and cultivation.Correlation analysis with fruit flavor and TSS,fruit flavor and TSS-acid,TSS and TSS-acid ratio,total sugar and ratio of sugar to acid showed significant difference at p＜0.01 levels,and that for ratio of sugar to acid and TSS-acid ratio showed the significant difference at p ＜0.05 levels.The four most important fruit quality parameters were fruit weigh,fruit flavor or TSS,fat content and TSS-acid ratio according to cluster analysis,which were helpful for the evaluation and selection of Vietnamese coconut resources
