Embodiment 1

[0028] Grape Varieties: Sunshine Rose;

[0029] Grape planting method: conventional planting method, with a plant spacing of 1.2 meters and a row spacing of 2 meters;

[0030] Treatment Reagent: Melatonin, Melatonin, Molecular Formula: C 13 h 16 N 2 o 2 Molecular weight: 232.28, purity: not less than 95%, purchase channel: online order https: / / www.aladdin-e.com / zh_cn / ;

[0031] Treatment concentration and frequency: the application concentration is 5 μmol / L, and the application is applied twice in total. The first application time is before the fruit ripens and the soluble solids (TSS) content reaches 5.0; the second application time is after the first application 7 days.

[0032] Treatment method and dosage: flushing in the same direction, with an average of 18L per plant.

[0033] Determination of fruit aroma content, the results are shown in Table 1.

Embodiment 2

[0035] Except that application mode is drip irrigation, average every application 15L, application time TSS average content 6.0, the 2nd application is 10 days after the 1st application, all the other are identical with embodiment 1.

Embodiment 3

[0045] Except that the application concentration of melatonin is 5 μmol / L, the application method is drip irrigation, with an average of 15 L per plant, the first application time is when the average fruit TSS content is 6.0, and the second treatment is 10 days after the first treatment. , all the other are identical with embodiment 1.

Abstract

The invention provides application of melatonin in enhancing aroma of Shine-Muscat grape fruits and belongs to the technical field of plant growth regulation. According to the application, the melatonin can significantly enhance the aroma of Shine-Muscat grape fruits. After application, compared with untreated controls, the total quantity of aromatic substances of fruits is increased by 4 times orabove after melatonin treatment, the type of aromatic substances of fruits after melatonin application is 1.65 times that of control fruits, the total quantity of aromatic substances is 4.32 times that of the controls, the aromatic substances with Muscat characteristics are increased by 4 times or above, and the characteristic aromatic substance with the highest content is 2-Hexenal, (E)-, whichis 4.54 times that of the controls. The melatonin treatment can increase the contents of alcohols, aldehydes, terpenes and other aromatic substances.

Description

technical field [0001] The invention relates to the technical field of plant growth regulation, in particular to the application of melatonin in improving the fruit aroma of sunshine rose grapes. Background technique [0002] The grape variety Sunshine Rose is imported from Japan and is a hybrid of 'Anyunjin 21' and 'Bainan'. It is a European and American hybrid. The peel is yellow-green, the flesh is emerald and firm, with rose fragrance and high sugar content. It matures in mid-to-late September. Because of its good quality and high planting efficiency, it has a broad early stage of development. At present, the planting area of ​​this variety in my country exceeds 500,000 mu, and the planting area continues to expand every year. This variety grows vigorously and requires a high level of planting technology. The quality of the fruit in production is uneven, and there is a phenomenon of insufficient rose aroma. At present, there is a lack of a method for effectively impro...
