| 中文摘要: |
| 本研究以江西赣南地区猕猴桃主栽品种‘东红’为试材,调查其结果母枝粗度分布范围并划分为5个等级粗度,探究不同等级粗度结果母枝‘东红’猕猴桃果实品质的差异,并应用主成分分析法进行综合评价,可为‘东红’猕猴桃冬季修剪时适宜结果母枝的选留提供依据。研究结果表明,不同粗度结果母枝的‘东红’猕猴桃在果实风味品质、色泽指标等方面均存在差异。结果母枝粗度在10-12 mm时,单果重、果实横纵径均最大；结果母枝粗度在8-10 mm时,果实干物质、可溶性糖、可滴定酸、Vc、可溶性固形物、类胡萝卜素、叶绿素含量均为最大；随着结果母枝粗度的增加,果肉色调角、可滴定酸含量下降,固酸比、糖酸比上升。主成分分析综合评价表明,‘东红’猕猴桃结果母枝粗度为8-10 mm的果实综合品质最佳,随着结果母枝粗度增加,果实综合品质下降,结果母枝粗度为16 mm以上的果实综合评价最低。 |
| 英文摘要: |
| In order to investigate the bearing base shoot distribution and determined fruit quality of different bearing base shoot on ‘Donghong’ (Actinidia chinensis), the ‘Dong Hong’ kiwifruit in Gannan area was as the test materials, difference analysis and principal component analysis were used in the comprehensive evaluation analysis. The results showed that the fruit of ‘Dong Hong’of the bearing base shoot with different diameter were different in terms of flavor quality and color index. The fruit weight、longitude、latitude and firmness were the largest in the bearing base shootdiameter of 10-12mm.The dry matter、soluble sugar content、TA、Vc、soluble solid content、carotenoid content、total chlorophyll content were the largest in the bearing base shoot diameter of 8-10mm.With the increasement of bearing base shoot diameter, the Hue angle and titratable acid content decreased, however the TSS/TA ratio and sugar/acid ratio raised.The comprehensive evaluation of principal component analysis showed that the fruitquality with the bearing base shoot diameter of 8-10mm was the best, and the fruit quality decreased with the increasement of the bearing base shoot diameter, the fruit quality with the bearing base shoot diameter of more than 16mm was the lowest. |
