Pollination and Fruit Set
Cashew timber are protandrous, that means their female and male flowers mature at totally different instances. This prevents self-fertilization and encourages cross-pollination by bugs, reminiscent of 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 accommodates 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 model). If these pollen grains are appropriate with the feminine flower, they germinate and develop down the model, reaching the ovary to fertilize the ovule.
As soon as fertilization happens, the cashew fruit begins to develop. The swollen receptacle types the cashew apple, whereas the true fruit (cashew nut) develops inside a tough shell.
Elements Affecting Pollination and Fruit Set
- Sufficient insect pollinators: A ample quantity and variety of insect pollinators are important for efficient cross-pollination.

- Humidity: Average 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 development produce extra flowers and fruits.
- Illness and pest administration: Controlling illnesses and pests can assist defend flowers and fruits.
- Administration practices: Correct pruning and cover administration create an atmosphere 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 | Accumulating and spraying pollen from male flowers onto feminine flowers utilizing a sprayer. |
