Embodiment 1

[0034] (1) Reagent treatment

[0035] ①The fruit of the red pear variety 'Zaosuhong' was collected from the Zhengzhou Comprehensive Experimental Station of the National Pear Industry System in 2015 and 2016. 40 days after blooming, cover the fruit with an opaque double-layer fruit bag until it reaches the physiological maturity period. After the mature fruit is harvested, it will be transported back to the laboratory immediately. Rotten fruit is used as a treatment.

[0036] ② The test was divided into 3 groups, the control group and the treatment group, see Table 1 for details. After soaking, put them in a dark environment to dry.

Abstract

The invention discloses application of 1-methylcyclopropene as a red pear coloring promoter, belonging to the technical field of fruit coloring. The condition that accumulation of red pear peel anthocyanin can be induced by an ethylene inhibitor 1-MCP is firstly discovered. The 1-methylcyclopropene is very good in coloring effect and deep in color and luster, and the red pear is good in appearance quality. The invention further discloses a method for promoting red pear coloring. The method comprises the steps of carrying out illuminating coloring on red pears which reach the physiological mature stage and are not colored, and before illumination, fumigating the red pears in a 1-methylcyclopropene atmosphere. By using the coloring method, the coloring time of the red pears is shortened, maintaining of the inner quality of the red pears is facilitated, ethylene release of fruits can be inhibited by 1-MCP, the storage time of the fruits is prolonged and the market value of the red pears is increased. The method is reasonable in design, simple and convenient to operate and relatively low in demands in equipment, can be operated on a large scale, and can be demonstrated, popularized and applied to commercial orchards.

Description

technical field [0001] The invention relates to the technical field of fruit coloring, in particular to the use of 1-methylcyclopropene as a red pear coloring accelerator. Background technique [0002] Pear is a plant of the genus Pyrus in the family Rosaceae, a perennial deciduous fruit tree. my country is the birthplace of Pyrus, and there are rich Pyrus resources in the territory, and it is one of the countries with the most varieties of pears in the world. When the pear fruit is ripe, the color of the pericarp is generally yellow-green (or green, yellow) or brown, and there are relatively few types of red pericarp. [0003] In recent years, with the breeding of new varieties of red sand pear and the introduction of red Western pear varieties in my country, red pears have been cultivated in many places in China. However, the relative lack of coloring control measures in production affects the display of the unique appearance quality of the fruit and directly leads to a ...
