Question

What is bagging?

Answer 1

Hint: Pollination is a plant reproduction process in which pollen grains are transferred from the anther to the stigma. Cross-pollination and self-pollination are the two types of pollination. Pollen and stigma must be compatible for pollination to be successful. Pollen grains may be rejected due to incompatibility. This is unfavourable, particularly in commercial crop production. Artificial hybridization was created as a result.

Complete answer:
Bagging is a plant breeding technique for preventing self-pollination in bisexual blooms. The anthers of bisexual flowers are removed, a process known as emasculation, and the flower is then wrapped with a paper bag to protect it against pollen contamination.

Bagging is the process of wrapping emasculated flowers with a bag. For optimal pollination and fertilisation, pollen-stigma compatibility is critical. When compatible pollen is accepted by the pistil, fertilisation events begin, whereas incompatible pollen is rejected. The ability of a pistil to recognise its pollen is the outcome of long-term pollen-pistil contact as well as compounds generated by pollen. In hybridization,.

It's critical to understand the pollen-pistil interaction. It is one of the agricultural production enhancement program's creative methods. Through pollination, only the desired pollen grains are transferred to the stigma during artificial hybridization. This saves time and helps to avoid pollen rejection also the plants with the desired characteristics can be grown.

Artificial Hybridization:
A Step-by-Step Guide
Hybridization takes place in two stages:
i) Bagging
ii) Emasculation.

Hybridization is a process of selective breeding, as we all know. Anthers must be removed from a bisexual bloom before pollen grains can be released. Emasculation is the process of removing an anther with forceps. This step is not required in the case of unisexual blooms.

Bagging is a method of protecting emasculated flowers from unwanted pollen grains. Despite the fact that the flower is obscured by a bag, it achieves receptivity. Bagging is done before the flowers open in unisexual flowers.

The female blossom is totally protected from contamination thanks to emasculation and bagging. The required pollen are dusted on the stigma once the bloom has reached stigma receptivity. This has been resealed in preparation for future improvements.

Note: Artificial hybridization ensures that the correct type of pollen is transported to the flower's stigma. Furthermore, there is a good likelihood of fertilisation. This method allows for the development of a wide range of agricultural strains while also improving the quality of crops with desirable characteristics.
