Embodiment 1

[0027] During the commercial harvest period of 2011, at the Baishui Apple Experimental Station of Northwest Agriculture and Forestry University, randomly selected fruits with consistent maturity, good coloring, no mechanical damage, and no infestation by diseases and insect pests, including Honggala, Guoguang, Qinguan, Granny Smith, Honeycrisp, Pink Lady, Golden Delicious, Jonagold, Red Star, Fuji and other 10 varieties were transported back to the laboratory immediately after harvesting for dyeing test.

[0028] Under the vacuum degree of 0.06Mpa, 10 kinds of apples such as Honggala, Guoguang, Fuji, etc. were dyed according to the above method, and 20 fruits were taken for each kind for dyeing, repeated 3 times. The weight of a single fruit was weighed before and after dyeing to obtain the water absorption of the fruit, and the dyeing grade was counted according to the grading standard, and the correlation between the dyeing grade and the water absorption was analyzed.

Embodiment 2

[0033] During the commercial harvest period of 2011, apples were randomly selected in the orchards of farmers in Fufeng, Shaanxi, with uniform maturity, good coloring, no mechanical damage, and no pests and diseases. Immediately after harvesting, the apples were transported back to the laboratory for dyeing tests.

[0034] The degree of vacuum used in the Fuji apple dyeing test and the time to return to atmospheric pressure will affect the correlation between the dyeing level and the water absorption. The test condition when the correlation between water absorption and dyeing grade is the highest can be regarded as the best condition for Fuji apple dyeing. In this experiment, a total of 3 vacuum degree gradients were designed for comparison: 0.03MPa, 0.06MPa and 0.09MPa were used for dyeing experiments, and the time for returning to atmospheric pressure under each vacuum degree was set to 30S, 1min, 3min, a total of 9 treatments, each Each treatment was repeated 3 times, and ...

Embodiment 3

[0039] During the commercial harvest period of 2011, apples were randomly selected with consistent maturity, good coloring, no mechanical damage, and no pests and diseases. The harvesting places include Luochuan, Ansai, Fufeng, Yan'an, Tongchuan in Shaanxi, Yinchuan in Ningxia and Tianshui in Gansu, etc. The main Fuji apple producing area in the whole country. Immediately after harvesting, the apples were transported back to the laboratory for dyeing tests. Each production area was repeated 3 times, with 12 fruits each time.

[0040] It can be seen from Table 3 that in 2011, there were differences in the dyeing grade and water absorption of Fuji in the seven production areas of the country. The dyeing grade and water absorption in Luochuan area are the highest, while the dyeing grade and water absorption in Tongchuan, Tianshui, Yan'an, and Ansai areas are lower. Luochuan area is significantly different from Fufeng and Yinchuan in the degree of dyeing, and the difference is e...

Abstract

The invention relates to a method for evaluating the development situation of cuticles of mature apple fruits. The method is characterized in that the apple fruits undergo aniline blue dyeing under a 0.04-0.1MPa vacuum condition, and the water absorbing capacity before and after the dying and the dyeing area are determined to evaluate the development quality of the cuticles of the apple fruits. The method can reduce artificial factor errors, is accurate and objective, and is a scientific means for evaluating the development situation of the cuticles of the mature apple fruits in production.

Description

technical field [0001] The invention belongs to the technical field of postharvest physiology and fresh-keeping of horticultural products, and in particular relates to a method capable of evaluating the development status of corneum of apple fruit in the mature stage. Background technique [0002] Apple is an important fruit in my country and the world. my country's apple cultivation area and output rank first in the world, but the annual post-harvest loss rate reaches about 15% of the total output, which has a huge impact on apple production and economic benefits. Apple postharvest rot and water loss are the main reasons for postharvest loss, and the characteristics of fruit cuticles are closely related to fruit susceptibility to disease, rot and water loss. The main function of the corneum is to prevent water loss, regulate gas exchange, reduce ultraviolet light absorption, and prevent infection and damage by microorganisms, pests or the environment, etc. (Kerstiens G.Sign...
