Embodiment 1

[0031] In 2011, the red sand pear varieties "Meirensu" and "Mantianhong" fruits collected from the orchard of Xingyang Jindi Fruit Tree Fine Variety Demonstration Field in Zhengzhou City, Henan Province were used as materials, and the best coloring of "Meirensu" and "Mantianhong" temperature conditions were studied. Select 6 "Meirensu" and "Mantianhong" trees with basically the same age, growth potential and loading capacity as the test trees, and select 30 fruit shapes, sizes and planting parts on the periphery of each tree 40 days after full flowering. The basically identical young fruits are covered with opaque double-layer paper fruit bags until harvested.

[0032] Ripe fruits are transported back to the laboratory immediately after harvesting, and fruits with uniform size, no mechanical damage, no cracking, no pests and no rot are selected for treatment. The experimental treatments were as follows: the fruits were placed in a top-light plant growth chamber (Hangzhou Zeda...

Embodiment 2

[0036] In 2011, the red sand pear variety "Mantianhong" harvested from the orchard of Xingyang Jindi Fruit Tree Fine Variety Demonstration Field in Zhengzhou City, Henan Province was used as material to study the optimal coloring and lighting conditions of "Mantianhong". Select 6 "Mantianhong" trees with basically the same age, growth potential and load capacity as the test trees, and select 30 young fruits with basically the same fruit shape, size and insertion position on the periphery of each tree 40 days after full flowering Put light-tight double-layer paper fruit bags until harvesting.

Abstract

The invention discloses a method for coloring red Pyrus pyrifolia Nakai by induction after harvesting, which comprises a step of standing the Pyrus pyrifolia Nakai which achieves the physiological maturity stage and is not colored under the following environments for 5-10 days: (1) the temperature is between 12 DEG C and 22 DEG C; (2) the relative humidity is 70-90%; (3) UV-B (ultraviolet-B) luminous intensity is 0.1-0.5 mu mol.m<-2>.s<-1>, luminous intensity of white light is 250-550 mu mol.m<-2>.s<-1>; and the variety of red Pyrus pyrifolia Nakai is Mantianhong pear or Meirensu pear. The method is specially used for promoting the coloring of the red Pyrus pyrifolia Nakai fruits, and can promote the synthesis of anthocyanin in the red Pyrus pyrifolia Nakai fruits in a more effective manner and improve the appearance quality. Compared with the prior art, the effect of the method is better, and the method has pertinence. The method provided by the invention has the advantages of reasonable design, simple operation, low investment and operation cost, and is suitable for large scale operation.

Description

technical field [0001] The invention relates to the technical field of fruit coloring, in particular to a postharvest coloring method for red sand pears. Background technique [0002] Sand pear (Pyrus pyrifolia Nakai) is native to my country and is the most widely cultivated type in East Asia (Teng Yuanwen, Chai Mingliang, Li Xiugen. 2004. Historical Review and New Progress of Pyrus Classification. Journal of Fruit Trees 21:252-257.). When the sand pear fruit is ripe, the skin color is generally yellow-green (or green, yellow), brown or red, among which yellow-green is the most common (Teng Yuanwen, Shen Yuying, Zhou Xianzhang. 2005. Causes and solutions of sand pear peel rust spots. Fruit trees in southern China 34:52-56.). Compared with the other two types of peel color, there are relatively few types of red peel. For example, there are 304 domestic and foreign sand pear varieties collected in the early stage of China National Germplasm Resources Wuhan Sand Pear Orchard, ...
