Abstract. The flowering stage is one important stage in the mango fruit production. This stage is influenced by several environmental and internal factors. In subtropical regions, temperature is one important environmental factor in flowering process. The temperature at 18 °C during the day and 10 °C at night are needed to accelerate the flowering process. However, the temperature is not problem in tropic regions due to the temperature between two seasons (dry and wet season) is similar. The important factor that playing in flowering in tropic regions is drought stresses. At flowering stage of mango, the florigenic promoter (FP) is important promoter, while the vegetative promoter (VP) at the vegetative stage. Besides, the phytohormone also has a role in the flowering of mango. Phytohormones that play a role in flowering are auxin, cytokines, ethylene, and gibberellins. Furthermore, the increasing value of the C/N ratio could assist flowering initiation in mango plant.
