| 摘 要： | [目的]综合评价罗望子种质资源的果实品质和性状指标,为其开发利用提供参考依据.[方法]以主成分分析法将16个罗望子种质的15个品质和性状指标进行简化后,采用合理—满意度法对各品质和性状指标赋予合理权重,再计算出综合合理—满意度,分析评价其开发利用价值.[结果]罗望子8号的钙、铁和铜等矿物质含量最高(其中钙含量为2406.33 mg/kg),综合合理—满意度得分最高,为0.661分;罗望子9号的单果重中等偏上,可溶性固形物和总糖含量较高,总酸含量较低,综合合理—满意度得分次之,为0.646分;罗望子3号的单果重最重,为19.69 g,果味偏酸,可食率中等,综合合理—满意度得分排第3,为0.634分;罗望子13号的综合合理—满意度得分最低,为0.275分,综合利用性能最差.[结论]罗望子8号钙含量高,可作果汁或果酱品种开发利用;罗望子9号总糖含量中等偏高、风味佳和综合品质优良,可作干果食用;罗望子3号果型最大,可食率中等,种子可用于提取多糖,果肉可作加工原料;其他罗望子种质各有优异性状,可通过定向育种改良以获得更优良的种质资源.

| Abstract: | [Objective]Fruit quality and trait indicators of Tamarindus indica L. germplasm resources were comprehen-sively evaluated to provide reference for development and utilization of T. indica L. [Method]Principal component analysis were used to simplify 15 quality and trait indicators for 16 T. indica L. germplasm resources. Reasonable weights were given on each quality and trait indicator using rationalization-satisfaction method, then complex rationalization-satisfaction values were calculated and development values of each germplasm resource were analyzed. [Result]Calcium, iron and copper contents were the highest in T. indica L. 8(calcium content was 2406.33 mg/kg). Its rationalization-satisfaction score was the highest(0.661), and the nutrient value was high. T. indica L. 9 ranked the second in terms of rationalization-satis-faction score(0.646). It contained high soluble solid content and total sugar and low total acid content. Weight of single fruit was above the moderate level. T. indica L. 3 had the largest weight of single fruit(19.69 g), its flavor was sour, edible rate was at moderate level, the rationalization-satisfaction score(0.634) ranked the third. Rationalization-satisfaction score (0.275) of T. indica L. 13 was the lowest, and its complex utilization value was the worst. [Conclusion]T. indica L. 8 contains the highest calcium content, and can be developed as juice or jam. T. indica L. 9 contains high total sugar content and good flavor, the comprehensive quality is superior, therefore, it can be developed as dried fruit. Other germplasm resources con-tain different traits. Orientation breeding can be applied on them to upgrade the resources. |
