摘要: 分析叶面喷施不同浓度甘露醇对桃叶片叶绿素含量及桃果实品质的影响,筛选最优喷施浓度,为生产上提高桃果实品质提供参考。以春蜜、世纪之星、蓬仙15三个品种桃为试验材料,分别进行0(CK)、5 g/L(T1)、10 g/L(T2)、20 g/L(T3)、40 g/L(T4)甘露醇叶面喷施处理,测定桃叶片叶绿素含量、桃果实品质相关指标,并进行各生理指标的综合评价。结果表明,春蜜T1处理可溶性固形物含量、可溶性糖含量、果糖含量分别较CK显著提高18.38%、16.67%、17.56%;世纪之星T4处理果糖含量、葡萄糖含量、蔗糖含量、纵径、横径、单果重分别较CK显著提升14.03%、14.28%、13.01%、2.86%、4.58%、6.53%;蓬仙15 T4处理较CK显著提高果糖、葡萄糖和蔗糖含量,提升幅度分别为66.47%、62.09%、17.81%。综合分析,春蜜、世纪之星和蓬仙15提升果实品质的最适甘露醇浓度分别为5、40、40 g/L。

Abstract: The effects of foliar spraying different concentrations of mannitol on chlorophyll content of peach leaves and fruit quality were analyzed to screen the optimal spraying concentration and provide a reference for improving peach fruit quality in production. Three peach varieties, including Chunmi, Century Star and Pengxian 15, were used as experimental materials and treated with 0 (CK), 5 g/L (T1), 10 g/L (T2), 20 g/L (T3), and 40 g/L (T4) mannitol foliar spraying. Chlorophyll content of peach leaves and fruit quality-related indicators were measured, and a comprehensive evaluation of each physiological index was conducted. The results showed that the soluble solids, soluble sugar and fructose content of Chunmi under T1 treatment were significantly increased by 18.38%, 16.67% and 17.56%, respectively, compared with CK; the fructose content, glucose content, sucrose content, longitudinal diameter, transverse diameter and single fruit weight of Century Star under T4 treatment were significantly increased by 14.03%, 14.28%, 13.01%, 2.86%, 4.58% and 6.53%, respectively, compared with CK; the fructose, glucose and sucrose content of Pengxian 15 under T4 treatment were significantly increased by 66.47%, 62.09% and 17.81%, respectively, compared with CK. Comprehensive analysis showed that the optimal mannitol concentrations for improving fruit quality of Chunmi, Century Star and Pengxian 15 were 5, 40 and 40 g/L, respectively.
