None of them are suitable. The effective temperature of mango growth is 15-35℃, and the optimum temperature is 24-27℃. Only when flowering is above 20℃ can pollination and fertilization be normal. When the temperature is lower than 20℃, the anther will not crack and the pollen will not germinate, which will affect the results. Small trees can freeze to death at -3℃, and big trees will be severely frostbitten. Therefore, the local temperature is the limit that determines the suitability of mango planting. According to some data, the northern boundary of mango introduction in China is 27 43' north latitude, but generally speaking, the Tropic of Cancer is the northern edge of mango economic cultivation in China. As for going further north, it depends on the meteorological conditions in this place and whether there are conditions for economic planting.

When the annual average temperature is ≥22℃, the average temperature in Leng Yue is ≥ 13℃, and the absolute minimum temperature is >; 0℃ area can blossom and bear fruit normally. Jackfruit grows well in areas with sufficient water and annual rainfall above 1200mm.
