Embodiment 1

[0027] The red sand pear varieties "Meirensu" and "Mantianhong" fruits were collected from the orchard of Jindi Fruit Tree Fine Variety Demonstration Field in Xingyang, Zhengzhou City, Henan Province in 2011. The fruits were covered with opaque double-layer fruit bags 40 days after blooming. Until the physiological maturity period is reached, the mature fruits are immediately transported back to the laboratory after harvesting, and the fruits with uniform size, no mechanical damage, no cracking, no pests and no rot are selected for treatment. There are 8 treatments in total, including 5 single chemical treatments, which are: 1) 3mmol·L -1 GA (Shanghai Sangon Bioengineering Co., Ltd.); 2) 0.4mmol L -1 ABA (Shanghai Sangon Bioengineering Co., Ltd.); 3) 2mmol L -1 ETH (Shanghai Sangon Bioengineering Co., Ltd.); 4) 0.12mmol L -1 GNT (Sigma-Aldrich); 5) 2mmol L -1 MJ (Bailingwei Technology Co., Ltd.); at the same time, set up the treatment of 3 kinds of 2 chemical agents mixed, ...

Embodiment 2

[0047] The red sand pear varieties 'Meirensu' and 'Mantianhong' were collected from the orchard of Jindi Fruit Tree Demonstration Field in Xingyang, Zhengzhou City, Henan Province in 2011. The fruits were covered with opaque double-layer fruit bags 40 days after blooming. Until harvesting, the fruit is harvested 10 days before the fruit reaches physiological maturity, and immediately transported back to the laboratory, and the fruit with uniform size, no mechanical damage, no cracking, no pests and no rot is selected for treatment. A total of 6 treatments were set up, namely: 1) 3mmol·L -1 GA (Shanghai Sangon Bioengineering Co., Ltd.); 2) 0.4mmol L -1 ABA (Shanghai Sangon Bioengineering Co., Ltd.); 3) 2mmol L -1 ETH (Shanghai Sangon Bioengineering Co., Ltd.); 4) 0.12mmol L -1 GNT (Sigma-Aldrich); 5) 2mmol L -1 MJ (Bailingwei Technology Co., Ltd.); 6) 3mmol L -1 CCC (Chlormequat chloride) (Xi'an Bangyou Biotechnology Co., Ltd.), all solutions were prepared with 0.02% Twee-2...

Abstract

The invention discloses a method for promoting coloring of red Chinese pears by utilizing chemical agents. The method includes immersing uncolored Chinese pears which reach a physiological maturity stage into a coloring accelerator solution for 1-5 minutes, taking out the Chinese pears and drying the Chinese pears in the air, and placing the Chinese pears in an environment with a temperature of 12-22 DEG C, 70-90% of relative humidity, 0.1-0.5 micromole*m<-2>*s<-1> of luminous intensity of ultraviolet-b radiation (UV-B), 250-550 micromoles*m<-2>*s<-1> of luminous intensity of white light for 5-10 days, wherein the coloring accelerator comprises one or more kinds of ethephon, genistein and methyl jasmonate. According to the method, anthocyanin accumulation of the read Chinese pears can be effectively induced, the exterior quality of the pears can be improved, and the method and the coloring effect are better compared with the prior art after the immersing process of the red Chinese pears into the chemical agents.

Description

technical field [0001] The invention belongs to the field of fruit coloring, in particular to a method for promoting post-harvest coloring of red sand pears by using chemical agents. Background technique [0002] Sand pear 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) or brown, and there are relatively few types of red skin (Teng Yuanwen, Shen Yuying, Zhou Xianzhang. 2005. Causes of sand pear peel rust and countermeasures. Fruit trees in southern China 34:52-56.), mainly distributed in Sichuan and Yunnan provinces, among which there are about 40 local varieties and types of red sand pears found in Yunnan Province, ranking first in the country. In recent years, a new variety bred from the famous red sand pear n...
