The artificial vegetative reproduction by cutting in plants
Artificial vegetative reproduction
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 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 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 ?
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 .
The root cuttings , in which a section of the 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 are 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.
