The invention discloses a method for advancing the fruit maturation period of snowflake pears, and relates to the technical field of fruit and vegetable planting. According to the method, 15 days before fruit harvesting, a fruit ripening promoting agent is sprayed to fruit trees; the fruit maturation promoting agent is any one of 200 [mu] mol / L melatonin, 100 [mu] mol / L jasmonic acid or a mixture of 200 [mu] mol / L melatonin and 100 [mu] mol / L jasmonic acid. According to the method, the arbutin content and the soluble solid content in the early-harvested snowflake pear fruits can be increased, the hardness and the titratable acid content are reduced, and the change of the indexes is synthesized to powerfully prove that the snowflake pears are matured in advance.

The invention provides a kiwi fruit cultivation method and application in selenium enrichment, yield increase and quality improvement, and belongs to the technical field of fruit tree cultivation. According to the cultivation method of the kiwi fruits, the content of selenium in the kiwi fruits can be remarkably increased, the single fruit weight of the kiwi fruits can be remarkably increased, the content of soluble solids, soluble sugar and vitamin C in the kiwi fruits can be remarkably increased, the yield of the kiwi fruits can be increased, and the yield of the kiwi fruits can be increased. The content of titratable acid is remarkably reduced, the selenium content of the kiwi fruits is increased, the fruit yield is remarkably increased, and the fruit quality is improved.

The invention discloses a grape titratable acid whole genome selective breeding method. The method comprises the steps of data acquisition and preprocessing, variation site analysis, whole genome association analysis and model analysis and prediction. The invention relates to the technical field of grape genetic breeding. Aiming at quantitative character characteristics (influenced by multiple genes and environment) of titratable acidic characters, more than 10000 significant variation sites and key gene areas (such as candidate genes for coding malic enzyme and tartaric acid synthetase) covering tartaric acid and malic acid metabolism related pathways are positioned through whole genome association analysis, so that the one-sidedness of single gene analysis is avoided, and the quantitative character characteristics of the titratable acidic characters are obtained. The probability of false positive results is remarkably reduced, a model is constructed based on two-year phenotype data, and the influence of environmental noise is eliminated through cross validation, so that a prediction result is closer to a real genetic effect, and the problem that traditional phenotype selection is interfered by environmental fluctuation is solved.

The invention belongs to the technical field of agriculture and forestry research, and particularly relates to application of sinapic acid to improvement of fruit quality. Tests prove that the sinapic acid is applied to fruit trees, so that the quality of single apples, the longitudinal and transverse diameters of the fruits, the brittleness of pulp, the red saturation of the fruits, the soluble solid content, the titratable acid content, the fructose content, the glucose content, the sucrose content, the ascorbic acid content and the aroma substance content and types are improved. The test result is comprehensively analyzed, and 1 mmol / L of the foliage spray is best for improving the quality of the apple fruits.

The application discloses application of soybean peptides in fruit preservation. The application discloses application of soybean peptides in fruit preservation, expands the application range of the soybean peptides, and can significantly maintain the hardness, ethylene content, titratable acid content and soluble sugar content of apple fruits, maintain the superoxide dismutase activity of the fruits, reduce browning of the fruits, and enable long-term preservation of the apples and is safe and reliable.
