Question

Give two reasons why some plants are grown by the method of vegetative propagation. List two methods used to grow plants vegetatively.

Answer 1

Step 1: Reasons for Vegetative Propagation:
Plants are cultivated via vegetative propagation for these reasons:
1. Accelerated Growth: Compared to seed propagation, vegetative propagation, utilizing mature plant sections (stems, roots, leaves), leads to faster development of new plants.
2. Genetic Uniformity: This method yields offspring genetically identical to the parent, ensuring consistent traits in new plants, such as fruit quality or flower color.

Step 2: Vegetative Propagation Techniques:
Two prevalent methods are:
1. Cuttings: A section of a plant's stem, root, or leaf is severed and planted in soil or water, subsequently developing roots and a new plant.
2. Grafting: This process involves merging a plant part (scion) with the root system of another plant (rootstock), enabling the scion to grow on the rootstock.

Step 3: Summary:
Vegetative propagation facilitates rapid plant growth and guarantees genetic similarity to the parent plant. Common techniques include cuttings and grafting.
