Examples
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 20 mg / L ethephon water solution for 7 minutes, take it out and dry it, pack it in a 0.03 mm 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).
