Self-pollinating plants contain entire flowers (both stamen and pistil in the same bloom) and can easily transmit pollen from the stamen to the pistil even in the lightest wind. Pollinators that visit these blooms can help with pollination and increase plant output.
These plants, on the other hand, do not require pollinators to produce fruit. If you’re worried about a dearth of pollinators in your garden, gently tapping the stems or brushing against the plants as you walk by can mimic their actions.
The principal mating system found in grain crops and many vegetables is self-pollination, or more precisely, almost full self-pollination. The bulk of the world’s 50–60 major grain crops is mostly self-pollinated. Cross-pollination occurs in only a few crops (such as maize, rye, pearl millet, buckwheat, or scarlet runner bean). We know that the wild ancestors of self-pollinated crops are likewise self-pollinated now that the wild progenitors of the majority of grain crops have been reliably identified.
Self-pollination
Cross-pollination is used by the majority of plants. Those that rely on insects for pollination have vividly coloured blossoms with a pleasant aroma. Wind-pollinated flowers have lengthy stamens and pistils, as well as little or no petals.
Plants that pollinate themselves, such as peanuts, have smaller blooms. Some cross-pollinating plants can also self-pollinate if cross-pollination is unsuccessful. Peas, orchids, and sunflowers are among them.
Self-pollination occurs when the stamen and carpel mature at the same time and are positioned in such a way that pollen lands on the stigma of the flower. This form of pollination does not necessitate the plant to provide nectar and pollen to pollinators as nourishment.
Examples
- Wheat, barley, oats, rice, tomatoes, potatoes, apricots, and peaches are some examples of self-pollinating plants. Cross-pollination is possible in many plants that are capable of self-pollination.
- Apples, plums, pears, raspberries, blackberries, blackcurrants, strawberries, runner beans, pumpkins, daffodils, tulips, heather, lavender, and most blooming plants are examples of plants that employ insects for cross-pollination.
- Grass, catkins, dandelions, maple trees, and goat’s beards are examples of plants that use the wind to pollinate each other.

How to hand pollinate chilli plants?
To start growing chilli plants from seed, fill a seed tray halfway with any multi-purpose compost. Plant the seeds in furrows, cover them with soil and water them. They should now be kept at a temperature of 18 degrees in a heated propagator or on a warm windowsill and should be ready to prick out in 3-4 weeks. A full chilli growing guide may be found here.
A conservatory is ideal for producing chillies since the covered area helps to imitate the chillies’ natural growing circumstances and gives you complete control over the plants’ surroundings. The major issue you may encounter is an increase in water use as a result of the warmer weather.

Advantages and Disadvantages
Cross-pollination is beneficial because it allows for species variation by combining the genetic information of different plants. It does, however, rely on pollinators that will wander from plant to plant.
Self-pollination produces more uniform progeny, which means the species is less disease resistant as a whole. It does not, however, need to spend energy attracting pollinators and can spread outside locations with sufficient pollinators.
Adaptation for self-pollination
Self-pollination is favoured in nature by one of the following floral adaptations:
Homogamy:-Homogamy is a situation in which the anther and stigma of bisexual flowers mature at the same time, allowing for self-pollination. The stigma collects pollen grains from the anthers of the same flower through the agency of wind or insects in this situation. Mirabilis, Ixora, Sunflower, and so on.
Cleistogamy: Some bisexual blooms never open due to cleistogamy. They are little and inconspicuous at times, and they remain closed. As a result, pollen grains can only fertilise the stigma of the same flower. Cleistogamy is the term for this situation, and cleistogamous flowers are the flowers that result from it. Commelina benghalensis, Impatiens (Balsam), Arachis hypogea (Groundnut), and other species are examples.
Conclusion
The plant is fertilised when pollen is transported from the anther in the stamen to the stigma in the pistil.
