Explanation:
Plants grow from small, scaly rhizomes, which can be divided for propagation. Commercial propagation is from softwood cuttings in early spring (322) under mist using bottom heat. Leaf cuttings have also been successful
(a) Seed is the primary method used for propagating seasonal annuals commercially.
Many seasonal annuals are bred to produce seeds that are consistent in size, shape, and color, making them easy to plant and grow.
Corms and bulbs are usually used for the propagation of perennial plants, while root cuttings are primarily used for propagating woody plants such as trees and shrubs.
Seasonal annuals are plants that complete their life cycle within a year. They grow, flower, produce seeds, and die in a single season.
Examples of seasonal annuals include marigolds, petunias, and zinnias, among others.
The most common method of commercially propagating seasonal annuals is through seed propagation. Seeds of seasonal annuals are produced in large quantities and are relatively easy to store, transport, and plant.
Also, breeding programs for many seasonal annuals focus on developing new cultivars that produce consistent and desirable seed characteristics such as size, shape, and color.
This consistency helps to ensure uniformity in the plants grown from the seeds, making them ideal for commercial production.
On the other hand, corms and bulbs are primarily used for propagating perennial plants, which live for more than one year.
Corms and bulbs are specialized storage structures that contain the necessary nutrients for the plant's initial growth, and they also help the plant survive harsh environmental conditions.
For example, tulips and daffodils are propagated through bulbs, while gladioli and crocuses are propagated through corms.
Root cuttings, on the other hand, are typically used for propagating woody plants such as trees and shrubs.
In this method, a piece of the root system is cut and planted, and it will eventually produce a new plant.
This method can be more time-consuming and challenging than seed propagation, but it is useful for plants that do not produce seeds or are difficult to propagate through other methods.
