Abstract: 【Objective】 To clarify the effects of fruit quality of different concentrations of exogenous ALA on the fruit quality Crimson seedless grapes.【Method】In this experiment, Krissom seedless grape was used as the test material to the effects of different concentrations of exogenous ALA on glycolic acid content, longitudinal and transverse diameter, anthocyanin content and PAL enzyme activity of Kerrison seedless grape were studied.【Results】ALA treatment with different concentrations significantly increased the longitudinal and transverse diameter of fruits, the chlorophyll relative content increased by 12.03%, and the average ratio of sugar to acid in fruit was 106.21% higher than that in the control. The accumulation of anthocyanin and the activity of the associated PAL increased significantly, with an average increase of 194.71% and 82.35% respectively. Anthocyanin was positively correlated with PAL enzyme activity and soluble sugar content in Crimson peel, and was negatively correlated with titratable acid content. 【Conclusion】 Compared with the control, the best promotion effect was 100 mg/L of ALA. Exogenous ALA treatment can improve the fruit size and sugar-acid ratio of Crimson seedless grape and promote fruit flavor and color to a certain extent

摘要: 【目的】研究不同浓度外源ALA对克瑞森无核葡萄的果实品质效果。【方法】以露地克瑞森无核葡萄为材料,研究不同浓度的外源ALA对克瑞森葡萄果实糖酸含量、果实纵横径、花青素含量及PAL酶活性的影响。【结果】不同浓度的ALA处理能明显增加果实的纵、横径;叶片内叶绿素相对含量提高12.03%;果实糖酸比平均值与对照相比增幅可达106.21%;果皮花青素的积累量及其合成相关PAL的活性显著升高,与对照相比,平均增幅分别达到194.71%、82.35%;克瑞森果皮中花青素与其合成相关的PAL酶活性、果肉中可溶性糖的含量具有极显著正相关关系,与果肉中可滴定酸的含量呈明显负相关关系。【结论】以100 mg/L 的ALA的促进效果最好,外源ALA处理可提高克瑞森无核葡萄果实大小及糖酸比,促进果实风味,并在一定程度上促进其着色。
