Question

Stem cuttings are commonly used for propagation in
(a)Rubber
(b)Mangoes
(c)Sugarcane
(d)Jasmine

Answer 1

Hint: Stem cuttings are a form of reproduction known as vegetative propagation. Stem cuttings are portions of stems that are cut from the main body of the parent plant, which when planted in the soil can give rise to a new plant. This is seen in a cash crop that is used to produce jaggery.

Complete answer:
Stem cuttings or sections of the stalks known as ‘setts’ are used to propagate sugarcane. Each of these sets contains one or sometimes more buds that are located in the root band of the node. They are embryonic shoots which consist of a miniature stalk with a number of small leaves. These buds sprout when the conditions are favorable and give rise to a new primary stalk whereas from the primordial node the set roots originate.
Thus these stem cuttings are an effective way of propagation in sugarcane.

Additional Information:
 -Vegetative reproduction is a type of asexual reproduction in which new plants arise from vegetative parts of the parent plant like roots, stems, and leaves.
-Some plants show this naturally in the form of root tubers, suckers, offsets, etc.
-Artificial vegetative propagation is carried out by humans on the fields by cutting and planting stems or leaves. This is seen in plants like rose and sugarcane where a portion of the stem is cut and planted to give rise to a new plant.
-Artificial vegetative propagation can be also seen in the form of grafting and layering on the fields or in the form of tissue culture in the laboratories.
So, the correct answer is, “Sugarcane”

Note: -In some plant stem sections may be cut and instead of planting in the soil, they may be attached to the step of a different plant that is rooted in the ground. This type of artificial vegetative propagation is known as grafting. The tissues of the graft become integrated with the host plant and grow as a hybrid plant with time.
-In some plants layering can be done, where instead of cutting the stem, a part of the stem can be inserted into the ground and covered with soil.
