Question

How do the ornamental plants propagate? Mention the method of propagation for the following:
(i) Jasmine (ii) Rose
(iii) Bougainvillea (iv) Hibiscus

Answer 1

Answer:

Explanation:

We can grow many plants from one plant by using the man-made methods. The process of growing many plants from one plant by man-made methods is called artificial propagation of plants. A number of methods of artificial propagation of plants are used in agriculture (for raising crops), and horticulture (cultivation of vegetables, fruits and flowers). The three common methods for the artificial propagation of plants are:

1. Cuttings,

2. Layering, and

ADVERTISEMENTS:

3. Grafting.

We will now describe all these methods, one by one. Let us start with the cuttings method for the artificial propagation of plants.

1. Cuttings :

A small part of a plant which is removed by making a cut with a sharp knife is called a ‘cutting’. A cutting may be a piece of stem, root or even a leaf. While making a cutting, care should to take to see that there are some buds on it.

ADVERTISEMENTS:

In this method, a cutting of the parent plant (say, of stem or shoot) having some buds on it is taken and its lower part is buried in the moist soil. After a few days, the cutting develops roots; shoot, and grows into a new plant. Cuttings are a means of asexual reproduction in plants. The new plant formed from a cutting is exactly similar to the parent plant.

The plants like rose, Bougainvillea, Chrysanthemum, grapes, sugarcane, bananas, and cactus, etc., can be grown by means of cuttings. For example, rose plants are propagated (or reproduced) by means c cuttings from stems (or shoots) as follows: A piece of stem (or side shoot) having bud is cut from an; existing rose plant with the help of a knife. The lower part of this Gutting is buried in moist soil. After a few days, the end of cutting buried in soil develops roots and later on grows to become a new rose plant. An advantage of cuttings method is that by using this method we can produce many new plants from just one plant quickly, without waiting for flowers and se

Methods of propagation

Explanation:

The ornamental plants propagate by vegetative reproduction methods. There are many methods of vegetative reproduction like layering, budding, cutting, grafting, etc.

Method of propagation for the given plants are as follows:

1. Jasmine - layering.  Layering occurs when a branch touches the ground, whereupon it produces adventitious roots.
2. Rose – cutting . The rose cutting should be 6 to 8 inches in length measuring down the stem from the base of the bloom.
3. Bougainvillea – layering
4. Hibiscus- layering
