To trigger the formation of durian flower buds, both external and internal factors need to be considered. External factors include temperature and humidity in the environment, typically requiring a continuous 7-14 day period of drought in combination with specific temperature and humidity conditions. Internal factors involve nutrient transport and storage as well as the balance of plant hormones.

Phosphorus is related to energy storage and transfer in plants. Adequate phosphorus helps the plant accumulate enough energy during the flower bud induction period to support the formation and blooming of flower buds.

Potassium is involved in nutrient absorption and distribution, ensuring that the necessary nutrients reach the flower buds and other parts to promote flowering and reproduction.

Boron contributes to the synthesis of polysaccharides and proteins, which are crucial for the formation of flower buds. Proper boron supply can enhance the growth of pollen tubes and the pollination process, ensuring the successful pollination of flowers afterwards.

An adequate supply of these three nutrients is essential for the flower bud induction period and plant reproduction. They help the plant store enough energy and nutrients to support the formation and blooming of flower buds. Insufficient nutrient supply may impact flower induction and overall growth.

Therefore, AgroBridge suggests using Innotec® PK and Wuxal PK for durian pre-flower stage preparations.

Innotec® PK (Chloride Free)

1. Optimum nutrient balance for the flowering preparation stage.
2. High Phosphorus and Potassium
3. Increase the development of flowers and fruits
4. The ratio of N:P:K is adapted to the special nutritional needs of flower and fruit plants

WUXAL PK

1. Concentrated foliar fertilizer, high in Phosphorus and Potassium
2. To overcome the problem of Phosphorus and Potassium deficiency in a short time.
