crop propagation methods

crop propagation definition
Propagation can be defined as the multiplication of individual plants into new plants. There are two types of propagation i.e., sexual and asexual propagation. Sexual propagation is by seed, while asexual propagation which is also known as vegetative propagation is by vegetative organs such as stem, root and leaf

plant propagation method

Plant propagation is the process of creating new plants.

There are two types of propagation

:
sexual and asexual. Sexual reproduction is the union of the pollen and egg, drawing from the genes of two parents to create a new, third individual. Sexual propagation involves the floral parts of a plant. Asexual propagation involves taking a part of one parent plant and causing it to regenerate itself into a new plant. The resulting new plant is genetically identical its parent. Asexual propagation involves the vegetative parts of a plant: stems, roots, or leaves.
cuttings.







crop propagation and cultural practices

Sexual Propagation
Sexual propagation involves the union of the pollen (male) with the egg (female) to produce a seed. The seed is made up of three parts: the outer seed coat, which protects the seed; the endosperm, which is a food reserve; and the embryo, which is the young plant itself. When a seed is mature and put in a favorable environment, it will germinate (begin active growth). In the following section, seed germination and transplanting of seeds will be discussed.

crop propagation by seed

Germination will begin when certain internal requirements have been met. A seed must have a mature embryo, contain a large enough endosperm to sustain the embryo during germination, and contain sufficient hormones to initiate the process. In general, do not expect more than 65% to 80% of new seeds to germinate. From those germinating, expect about 60% to 75% to produce satisfactory, vigorous, sturdy seedlings.

Advantages Of Propagating From Cuttings

:
Asexual propagation can be used for plants with low seed production.
Propagating asexually allows for clones.
Uniform and true to type offspring can be ensured through asexual propagation.
Can often be easier and more economically viable.
Undesirable features such as excessive thorns can be minimized by selecting propagation material from less thorny plant parts. The same method can be used to cultivate desirable qualities such as interesting variegated growth.

Disadvantages of Propagating From Seed

:
Plants propagated from seed risk not being true to type (flowers, growth habit etc. won't be the same as the mother plant) due to

cross pollination

.
In some cases Sexual propagation can be slower than asexual.
Some plants produce non-viable seeds.
Some seeds are very difficult to germinate.
The seed of certain plants need require to be treated chemically or mechanically to stimulate germination.
Certain plants don’t produce seed at all.
In most cases seedlings have to go through an immature phase before maturing and fruiting.
