摘要:
为综合评价不同茶树种质资源花器的矿质营养品质差异,采用电感耦合等离子体发射光谱仪法测定了23份茶树种质资源花器中18种矿质元素含量,并对其进行相关性分析、聚类热图分析和主成分分析。结果表明,茶树种质资源花器中18种矿质元素含量具有较为丰富的多样性,变异系数为11.86%~48.96%,遗传多样性指数为1.19~2.19;钾、钙、镁、磷、硫、铝、硼、钡、铬、铜、铁、锰、钛13种元素含量呈正态分布,钠、钴、镍、锌4种元素含量呈正偏态分布,硒含量呈负偏态分布;聚类热图分析将23份茶树种质资源花器分为3个类群;经主成分分析,矿质营养品质综合得分排在前5位的茶树种质资源花器材料依次为‘平阳特早茶’‘巴渝特早’‘黄金芽’‘名山早311’和‘大红袍’,可作为优先开发利用的材料。研究结果可为茶树种质资源的创新利用和茶树花产品的开发提供科学依据。
