Embodiment 1

[0020] Soak freshly harvested mango (Mangifera indica L., the same below.) fruit with 4mg / L ethephon aqueous solution for 3 minutes, take out and dry and store in a storage warehouse at 20°C with 0.03 mm polyethylene plastic film bag;

[0021] The diameter of mango lesions soaked in 4 mg / L ethephon aqueous solution was 52% lower than that of the control (see Table 1).

[0022] The effect of controlling mango anthracnose with storage time of 5d, 7d, 9d, 11d, such as figure 1 shown. From figure 1 It can be seen that the mangoes treated with low concentration of ethephon had significantly smaller lesions than the control during the whole storage period. It showed that ethylene effectively controlled postharvest anthracnose in mango.

[0023] The effect of controlling mango anthracnose with a storage time of 14 days, such as figure 2 shown.

Embodiment 2

[0025] Soak the mango fruit 24 hours after harvesting in 40mg / L ethephon water solution for 5 minutes, take it out and dry it, pack it with 0.03 mm polyethylene plastic film bag and store it in a storage warehouse at 25°C;

[0026] The lesion diameter of the mango soaked in 40 mg / L ethephon aqueous solution was 46% lower than that of the control (see Table 1).

[0027] The effect of controlling mango anthracnose with a storage time of 14 days, such as figure 2 shown.

Embodiment 3

[0029] Soak the mango fruit 48 hours after harvesting in 20mg / L ethephon water solution for 7 minutes, take it out and dry it, pack it in a 0.03mm polyethylene plastic film bag and store it in a storage warehouse at 22°C;

[0030] The lesion diameter of the mango soaked in 20 mg / L ethephon aqueous solution was 49% lower than that of the control (see Table 1).

Abstract

The invention discloses a method for controlling anthracnose of normal temperature preserved mangoes by using ethephon. The method comprises the following steps: soaking mango fruits which are harvested within 48 hours into a 4-40mg / L ethephon solution for 3-7 minutes, taking out, drying the mangoes at the room temperature, packaging by using polyethylene plastic film bags of which the thickness is 0.02-0.04mm, and preserving at 20-25 DEG C. By adopting the method disclosed by the invention, disease resistance of the mangoes is firstly induced by low-concentration ethylene generated from decomposition of the ethephon before maturation acceleration of the mangoes, so that the anthracnose can be effectively prevented. The method is simple to operate, low in cost, high in application efficiency and easy to popularize, application of chemical fungicides in preservation of the mangoes can be replaced, and thus the food quality security is improved; the mangoes can be preserved without a refrigeration house or low-temperature transportation, so that the energy is saved, the environment is protected, and the method is a low-carbon preservation technique. When the mangoes are treated by using the method disclosed by the invention, very good economic benefits and social benefits can be created.

Description

technical field [0001] The invention belongs to the technical field of mango preservation, in particular to a method for controlling mango anthracnose in normal temperature storage and transportation by using ethephon. Background technique [0002] Mango (Mangifera indica L.) has the characteristics of bright and beautiful skin and flesh color, tender flesh, good flavor and strong aroma. It is very popular among domestic and foreign consumers and is known as the "king of tropical fruits". Mango is one of the top five tropical fruits in the world, distributed in almost all tropical and subtropical countries and regions (Tian Mixia et al., 2007). China is one of the major mango producing countries, ranking fourth in the world in terms of output and area. Mango production is mainly distributed in Hainan, Guangdong, Guangxi, Sichuan, Yunnan, Fujian, Taiwan and other provinces. Mango has high commodity value and remarkable economic benefits. It is the main pillar industry for f...
