What You Need To Know About Controlled Pollination

By David Jackson


Control-pollination is a scientific procedure that seeks to improve the quality of a plant and ensure that the offspring from the plant have quality genes. Controlled pollination is transferring pollen from a male plant species to a female plant for purposes of reproduction. A small amount of pollen is harvested from the male plant reproductive parts and put on the female parts; these procedures are mainly carried out in farms doing horticulture farming.

This form of pollen transfer is usually necessary when you want to maintain and establish a pedigree breeding population. The technique is also important in controlling inbreeding within a breeding population. This technique is also effective in crossbreeding and back-crossing among species. Generally, the technique is designed and managed in a special way to produce seeds that have greater genetic characteristics. The seeds produced also have a greater genetic uniformity compared to the plants that are spontaneously pollinated. Pollen contamination issues are also eliminated.

Usually, hand-pollination is usually necessary when you want to control pollination in a flower and ensure it gives fruits. To accomplish this, you just need to paint the stigma with pollen from the male flower. Hand pollinating usually depend on the type of flower, where it can be simple in others and difficult in others. However, this depends on the flower structure that usually vary with different species.

Contrarily, the removal of male parts or emasculation can be carried out in instances where control-pollinating has been done. This essentially aids in the elimination of self-contamination. Nevertheless, there is never a need to be apprehensive about self-sterile species thus emasculation may not be necessary. Also, the technique calls for pollen transfers to be undertaken only when flowers are ready for pollinating. Because this remains challenging, the pollens ought to be collected and stored much earlier.

At the same time, bagging is an essential requirement in all pollinating operations. The female or the receptive flowers should be covered prior to anthesis or flowering so as to protect the stigma from contamination until the desired pollen is applied. Usually, the bags used are the semi-transparent treated bags. The bags are used by placing them over the shoot tip. They should be firmly fitted to ensure they are secure.

With the right factors, natural pollination should occur. Factors such as ideal temperature allow plants to pollinate naturally. The bees in the farms are also excellent pollinators agents, and they get attracted to the most colorful flower. You can, however, not depend on bees because their population is dependent on weather condition.

Nature is unpredictable, and individuals must embrace hand pollinating techniques in their ventures. Hand pollinating gives a person the benefit of choosing the best quality of pollen for fertilization, and this leads to high yields.

On the other hand, pollen may be applied through a wide range of methods efficiently through the controlled technique. Basically, control technique of pollinating is usually an important aspect in plant breeding, as well as in hybrid seed production. Although there are many techniques for the control method, the choice of the method used depends on the type of crop. Nevertheless, mechanical pollinating control is the widely used although it is time-consuming and labor intensive.
