The flowering and fruit-setting stages are critical periods in mango production management. Adverse weather, pest and disease damage, or improper fertilizer and water management often lead to significant blossom and fruit drop, resulting in economic losses. Therefore, proactive steps must be taken to ensure normal flowering and fruit development.

Application method for Brassinolide and 6-BA on watermelons: Soak de-hulled seedless watermelon seeds in either a 150 mg/L 6-BA solution or a 4,000-fold diluted natural brassinosteroid solution for 8 hours; incubate at a constant temperature of 32°C for germination, and then raise the seedlings in a seedbed.

The period spanning from the onset of flowering to the swelling of young fruitlets constitutes a critically important stage in the grape growth cycle. The effectiveness of management during this phase directly determines both the yield and quality of the grapes produced in the current year.

Flower bud differentiation is the critical factor determining high yields, stable production, and superior quality in crop fruit production. Only through effective management during this specific period can high crop yields be guaranteed.
