Pollination and Fruit Set
Cashew timber are protandrous, that means their female and male flowers mature at completely different occasions. This prevents self-fertilization and encourages cross-pollination by bugs, comparable to bees and thrips. Efficient pollination is essential for profitable fruit set in cashew timber.
Within the early phases, male flowers (panicles) emerge first, releasing pollen through the early morning. Because the season progresses, feminine flowers (spikelets) develop. Every spikelet incorporates a single pistil with two kinds projecting from its tip.
When a pollinator lands on a male flower, it collects pollen grains on its physique. Because it strikes to a feminine flower, a few of these pollen grains are transferred to the stigma (the receptive a part of the fashion). If these pollen grains are appropriate with the feminine flower, they germinate and develop down the fashion, reaching the ovary to fertilize the ovule.
As soon as fertilization happens, the cashew fruit begins to develop. The swollen receptacle kinds the cashew apple, whereas the true fruit (cashew nut) develops inside a tough shell.
Components Affecting Pollination and Fruit Set
- Ample insect pollinators: A enough quantity and variety of insect pollinators are important for efficient cross-pollination.
- Optimum temperature: Temperatures between 25-32°C (77-90°F) favor pollination and fruit set.
- Humidity: Reasonable humidity ranges (50-70%) promote insect pollination.
- Water availability: Constant water provide throughout flowering and fruit improvement is essential.
- Tree well being: Wholesome timber with vigorous vegetative progress produce extra flowers and fruits.
- Illness and pest administration: Controlling illnesses and pests might help defend flowers and fruits.
- Administration practices: Correct pruning and cover administration create an surroundings conducive to pollination.
- Pollination methods: In areas the place pure pollinators are inadequate, synthetic pollination strategies might be employed to enhance fruit set.
| Pollination Method | 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. |
