REPRODUCTION OF PLANTS

The multiplication of plants is the agronomic practice that allows to obtain new plants.
The ways to achieve this are many and very different from each other.
The first important distinction to be made is to consider that the reproduction of plants can take place:
  • sexually;
  • vegetatively.

Sexual reproduction

This type of multiplication occurs by seed which is nothing more than a plant in rest or inactivity born from the pollination process which is followed by the development of the ovule. This type of reproduction is used to obtain individuals with new characteristics compared to the parents as the genetic patrimony of the new organism, since it is formed from the combination of the genetic heritages of the "mother plant" and the "father plant" or more precisely from the union of two gametes (derived from pollen and ovule) the individuals that will be born will be similar but not equal to the parents.

Vegetative reproduction

Vegetative multiplication, on the other hand, consists in obtaining from a portion of plants a new individual that will be identical to the mother plant. This is possible as various parts of different plants (leaves, roots, branches, stems ...) have the ability to give rise to new individuals without therefore there being any variation in the genetic heritage.
This practice is used above all for the reproduction of ornamental and horticultural plants and becomes indispensable in the reproduction, for example, of exotic plants that in our climatic conditions are unable to bloom and therefore to produce seeds (like almost all the plants we keep in our homes).
