- Water availability: Constant water provide throughout flowering and fruit improvement is essential.
- Tree well being: Wholesome timber with vigorous vegetative development produce extra flowers and fruits.
- Illness and pest administration: Controlling ailments and pests can assist shield flowers and fruits.
- Administration practices: Correct pruning and cover administration create an surroundings conducive to pollination.
- Pollination strategies: In areas the place pure pollinators are inadequate, synthetic pollination strategies may be employed to enhance fruit set.
| Pollination Approach | Description |
|---|---|
| Hand pollination | Utilizing a brush or cotton swab to switch pollen from male to feminine flowers. |
| Department shaking | Shaking branches to disperse pollen and promote cross-pollination. |
| Pollen spraying | Amassing and spraying pollen from male flowers onto feminine flowers utilizing a sprayer. |
