Question

What are the effects of cytokinins on plant growth?

Answer 1

Hint: Production of cytokinins occurs in the places of cell division and mostly present in the fruits and the roots of the plant. They are generally responsible for the growth and development of the plant body and increase their length.

Complete answer:
Cytokinins are growth boosters of the plant. The plant is originally produced in the regions where the plant is going through a process of cell division which is mostly the parts of the roots and shoots. They also help the plants in the production of the lateral growth of the shoot, in the production of chloroplasts in the leaves, and also in the production of new leaves itself. They also help the plants to get over with apical dominance and also aid the plant when there is a delay in the aging of the leaves. One of the functions of cytokinin also includes the breaking of the bird which is formed and also ending of the seed dormancy.

Additional Information:
- The cytokinins help the plant in the growth of their lateral bud and promotes the stage where the breaking of the bird is required and also help the plant to overcome the stage of seed dormancy.
- The flowers of the plants may or may not remain fresh for a lot of time but till how much time they will remain fresh depends upon the presence of the cytokinins which are responsible for keeping the flowers fresh for the maximum time possible.
- Cytokinins are specifically used in tissue culture to promote the cell division in the tissues which have already matured and induce more differentiation to the tissues of the plants.
- Cytokinins also help in the natural growth of the shoot and also helps in the stage of the adventitious shoot formation.
- Cytokinins also help in delaying the aging, or senescence of the leaves and the plant.

Note:
- Cytokinins help in the formation of the new leaves and organelles of the plant cell hence they are essential for the plant to be alive.
- Cytokinins are also used by gardeners to induce the development of the roots and the shoots of the plant at a much faster pace than it occurs naturally.
