The artificial vegetative reproduction by cutting in plants

Artificial vegetative reproduction

Plant cutting

Plant cutting

The artificial reproduction ( propagation ) is the creation of new life by many natural means that available to an organism ,  The artificial insemination such as in the vitro fertilization , the cloning and the embryonic splitting  and the cleavage .

Cutting plants stems and placing them in the compost is also a form of the artificial reproduction , where you can grow many plants from one plant by using the man-made methods , And it is called the artificial propagation of plants .

There is a number of methods of the artificial propagation of plants that are used in the agriculture ( for raising crops ) , and the horticulture ( the cultivation of the vegetables , the fruits and the flowers ) , The three common methods for the artificial vegetative propagation of plants are  cuttings , grafting and the tissue culture .

The cut

The cut is a part of the root , the stem or the leaf that taken from a plant for reproduction , Cutting is the process in which the stem of a plant is placed in the moist soil or the  water to generate a new root system , the  cut is a branch carrying many buds .

Cutting is a plant section that originates from the stem , the leaf  or the  root and it is capable of developing into a new plant , It is usually placed in warm and moist sand , And many plants especially the horticultural and the garden varieties are propagated through cuttings .

By the use of new techniques , many other plants formerly not susceptible to propagation through cuttings have more successfully reproduced , The plants that develop from cuttings are clones .

The plants such as the coleus and many plants are propagated through the stem cuttings where a portion of the stem containing the nodes and the internodes is placed in the moist soil and allowed to the root ?

In some species , the stems can start producing a root  when it placed only in the  water such as the leaves of  African violet that will root if kept undisturbed in the water for several weeks .

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

A cutting of the parent plant ( which has some buds on it ) is taken , and its lower part is buried in the moist soil , After a few days , the cutting develops the roots , the shoot , and it grows into a new plant .

The buds that buried inside the soil grow to form the root system of the plant , and the buds above the soil surface grow to form the shoot system of the plant  , Cutting is a means of the asexual reproduction in the plants , And the new plant formed from a cutting is exactly similar to the parent plant .

Cutting is known as striking or cloning , It is a technique for  asexually propagating in plants in which a piece of the stem or the root of the source plant is placed in a suitable medium such as the moist soil , the potting mix , the coir or the rock wool , It produces new roots and stems , and  becomes a new plant independent of the parent .

The plants like the rose , the bougainvillea , the chrysanthemum , the grapes , the sugarcane , the bananas , and the cactus can be grown by means of cuttings , And the advantage of cuttings method is that by using this method we can produce many new plants from just one plant quickly  without waiting for the flowers .

The rose plants are propagated by many types of cuttings from the stems  or the shoots  , when a piece of stem ( or the side shoot ) having bud is cut from an existing rose plant with the help of a knife , The lower part of this cutting is buried in the moist soil , After a few days , the end of cutting buried in the soil develops the roots and it grows to become a new rose plant .

Types of cutting

There are many types of cuttings , Many vegetative parts of a plant can be used , The most common methods are the stem cuttings , It is a cut portion of a stem that contains a terminal bud or the lateral buds and it is placed in growing media to produce the roots , in which a piece of stem is part buried in the soil , It includes at least one leaf node , The cutting is able to produce new roots , usually at the node .

Root cutting

Root cutting

The root cuttings , in which a section of root is buried just below the soil surface , and it  produces the new shoots ,  the root cutting uses the root or part of the root , The root cuttings are not as predictable as the other cuttings , It is more dependent on the seasonal influences  .

The eye cuttings which are pieces of foliated or defoliated stalks with one or more eyes  , the leaf cuttings , in which a leaf is placed on the moist soil  , And the scion cuttings which are the dormant ligneous woody twigs .

The softwood cuttings which is from soft and  succulent growth , And the hardwood cuttings which is from one year old growth , deciduous , and the  evergreen plants .

The semi-hardwood cuttings which is from woody broad-leaved plants with new shoots  , And the  leaf cutting consists of a leaf blade or leaf blade with petiole attached , the leaf-bud cutting consists of a leaf , petiole ,  and a short piece of stem with a lateral bud .
