Question

Stem cuttings are commonly used for the propagation of
A. Banana
B. Rose
C. Mango
D. Cotton

Answer 1

Hint: Stem cutting is a method of vegetative propagation in various plants where a portion of the stem is cut and placed in the soil. This cut portion then develops roots and shoots and a new plant is developed.

Complete answer: The stem cutting method is used to develop a whole new plant from an old plant that is similar to the parent plant which is known as cloning.
a) Banana: Banana grows by the method of asexual reproduction. New banana plants rise from the old plants. Banana plants are only grown vegetatively and there is no formation of seeds for the purpose of reproduction.
b) Rose: Rose grows by the method of vegetative propagation of stem. An appropriate section of the stem of the rose plant is cut and taken and is placed in the soil. This section then develops roots and shoots on which branches, leaves, and flowers arise, and a new plant is born.
c) Mango: Mango plants can be grown both asexually and sexually. Sexual means are the formation of seeds and the development of new plants from them. Asexually mango plants are grown with the help of grafting.
d) Cotton: Cotton plants grow sexually with the help of seeds. Thus, based on the above information we can conclude that stem cuttings are commonly used for the propagation of rose.
Hence, the correct answer is option B.

Note: For the purpose of stem cuttings the portion of the stem taken should be free from any kinds of pests and diseases. Moreover, the section should be taken such that it has at least one node. Also, the stem portion is generally taken from the end part of the plant.
