Artificial Methods of Vegetative Propagation in Plants

Artificial Methods of Vegetative Propagation in Plants

 

Some plants can be artificially propagated by using their vegetative parts and this is called artificial vegetative propagation. Following are the types of artificial vegetative propagation:

 

1) CUTTING:

 

  1. i) Cuttings are short pieces of stem with 2 or 3 nodes or buds.

 

  1. ii) The cutting is embedded in soil with one node.

 

iii) The adventitious roots and shoots grow from buds forming a new plant.

 

  1. iv) For example sugar cane, Balsam, Sweet Potato and rose etc.

 

2) GRAFTING:

 

  1. i) In this method branch of desired variety of plant is joined to another plant with well established root system.

 

  1. ii) The plant from which branch is taken is called scion and the plant from which it is joined is called stock.

 

iii) Scion and stock are tied in place to ensure grafting.

 

  1. iv) Grafting if helpful to obtain better varieties of fruits i.e. oranges, lime, lemon, mango and rose flowers etc.

 

3) CLONING:

 

  1. i) In this method a population of genetically identical individuals is produced from a single parent using parent’s vegetative cell under laboratory conditions.

 

  1. ii) A clone has the advantage that the good characteristics of the parent are passed as such to all the offspring.

 

4) UNDERGROUND STEMS:

 

  1. i) There are certain plants with underground stems, which also reproduce by vegetative propagation.

 

  1. ii) For example onion bulb, Canna or Iily and potato tuber.

 

 

Note: The pros and cons of secondary education are not exhausted. Another undoubted advantage of training is the ability to transfer a large amount of information over a short period of time. With this approach to learning, students acquire knowledge in a ready-made form. There is no need to look for ways to prove their truth. And among the significant drawbacks can be called the focus on memory, rather than thinking. Distance learning involves acquiring knowledge at home, without visiting a university you can not do, but it’s only a couple of weeks in winter and summer. Listening to lectures, taking exams and tests, it all seems easy and simple. In fact, the student needs a high self-organization, which is given very hard at home. How correspondence students study, it is easy for them or hard, can tell only those who have passed the entire institute course on the job.
