The present application relates to the technical field of fruit quality improvement, and particularly relates to application of
hyperoside in improving grape fruit
hardness. The scheme provided in the present application is verified by a large number of
field tests, after spraying the
plant with
hyperoside solution, the fruit
hardness of four grape varieties of'red double taste', 'rose
flavor','sunshine rose' and 'italy' is all significantly improved compared with the control group, wherein the
hardness of'red double taste' and 'rose
flavor' is greatly improved, the hardness is increased by about 20%~25% in the grape
ripening period, the hardness of'sunshine rose' and 'italy' is relatively small, the fruit hardness is increased by about 8%~16% in the grape color
softening period; in addition to improving the fruit hardness, spraying the
hyperoside solution can also promote the color uniformity of the grape fruit of some varieties, increase the
soluble solids content, reduce the titratable
acid content, and make the
fruit flavor better; the method is compatible with the conventional grape planting management measures, is easy to popularize and apply in the grape planting area, and can bring significant
economic benefits to the majority of growers.
