KT、6-BA对红颜草莓果实品质的影响

Effects of KT and 6-BA on the fruit quality in ‘Hongyan’ strawberry

以‘红颜’草莓为实验材料,在草莓花授粉后1、3、5、7、9d分别外源施加KT和6-BA两种细胞分裂素,旨在研究细胞分裂素类物质对草莓果实大小、重量及品质的影响。结果表明,外源施加KT和6-BA都显著增加了草莓果实体积和重量,并提高了可溶性糖、可溶性蛋白和游离氨基酸等营养物质的含量,抗坏血酸、花青素、总酚和黄酮等抗氧化物质的含量在经过细胞分裂素处理后也显著增加。说明细胞分裂素对草莓果实品质的提高具有积极作用,在草莓生产上具有一定的应用前景。

In this paper, the effects of KT and 6-BA on the size, weight and quality of ‘Hongyan’strawberry fruit were studied in 1, 3, 5, 7 and 9 days after pollination of strawberry. The results showed that exogenous application of both KT and 6-BA significantly increased the fruit weight and size, elevated the contents of soluble sugar, soluble protein and free amino acids in strawberry fruits. The content of antioxidant substances such as ascorbic acid anthocyanin, total phenols, and flavone were also enhanced by treatments of KT and 6-BA. The results indicated that cytokinin had a positive effect on strawberry fruit quality and has the application prospect in strawberry production.
