Within the early levels, 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 types 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 type). If these pollen grains are suitable with the feminine flower, they germinate and develop down the type, 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.
Elements Affecting Pollination and Fruit Set
- Enough insect pollinators: A enough quantity and variety of insect pollinators are important for efficient cross-pollination.

- Humidity: Reasonable humidity ranges (50-70%) promote insect pollination.
- Water availability: Constant water provide throughout flowering and fruit growth 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 atmosphere conducive to pollination.
- Pollination methods: In areas the place pure pollinators are inadequate, synthetic pollination strategies will 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 | Gathering and spraying pollen from male flowers onto feminine flowers utilizing a sprayer. |
