Embodiment 1

[0016] Spray the 50mg / L abscisic acid aqueous solution on the fruit surface of freshly harvested pineapple (Ananas comosus (Linn.) Merrill, the same below.). Polyethylene plastic film bags, dry the pineapples and store them in a storage warehouse at 20°C;

[0017] The black heart disease index of pineapple sprayed with 50mg / L abscisic acid aqueous solution was 85% lower than that of the control (see Table 1).

Embodiment 2

[0019] Spray 300mg / L abscisic acid aqueous solution on the surface of the pineapple fruit 24 hours after harvesting, pack the sprayed pineapple with a 0.02mm polyethylene plastic film bag to keep it moist for 7 hours, remove the polyethylene plastic film bag, and dry the pineapple Store in a warehouse at 25°C;

[0020] The black heart disease index of pineapple sprayed with 300mg / L abscisic acid aqueous solution was 90% lower than that of the control (see Table 1).

Embodiment 3

[0022] Spray the 500mg / L abscisic acid aqueous solution on the surface of the pineapple fruit 48 hours after harvesting, pack the sprayed pineapple with a 0.04 mm polyethylene plastic film bag to keep it moist for 9 hours, remove the polyethylene plastic film bag, and dry the pineapple Store in a warehouse at 22.5°C;

[0023] The black heart disease index of pineapple sprayed with 500mg / L abscisic acid aqueous solution was 90% lower than that of the control (see Table 1).

Abstract

The invention discloses a method for controlling a blackheart disease of normal-temperature stored pineapples by an abscisic acid. The method comprises the steps that an abscisic acid solution of 5-500mg / L is sprayed on the surfaces of the pineapples; and the sprayed pineapplesare is packed with a polyethylene plastic film bag of 0.02-0.04 millimetres and moisturized for 6-9 hours, then the polyethylene plastic film bag is removed, and the pineapples are aired and stored in a storehouse at the temperature of 20-25 DEG C. According to the method, the abscisic acid solution of 5-500mg / L is sprayed on the surfaces of pineapple fruits, so that the polyphenol oxidase activity and the peroxidase activity of the pineapples can be reduced effectively, and the pineapples can be prevented from suffering from the blackheart disease. The method is simple in operation, low in cost and high in applying efficiency, and can be popularized easily; at the same time, the storage period of the pineapples is prolonged, the problem of a farmer that the pineapples are difficult to sell can be solved effectively, and the enthusiasm of the farmer for planting pineapples is protected; and good economic and social benefits are achieved. The pineapples are kept fresh without a refrigerating storage and being transported at a low temperature, so that the energy is saved, the environmental protection is facilitated, and the method is a low-carbon preservation technology.

Description

technical field [0001] The invention belongs to the technical field of pineapple fresh-keeping, and in particular relates to a method for using abscisic acid to control black heart disease of pineapple stored at normal temperature. Background technique [0002] Pineapple (Ananas comosus (Linn.) Merrill) is a perennial evergreen herbaceous fruit tree of the family Bromeliaceae (Ananas Miller). First, it has become a pillar industry of the rural economy in South China. According to FAO statistics, my country's pineapple output in 2007 was 1.44 million tons, ranking third in Asia and fourth in the world, accounting for 7.63% of the world's total pineapple output. However, the post-harvest loss of pineapple is quite alarming. Some data show that 21% to 50% or even more pineapple is lost after harvest. Black Heart (or Endogenous Brown Spot) is one of the main diseases of pineapple, and has become an important hazard of fresh pineapple during shipping and refrigeration. Pineapp...
