Question

Roses and banana are usually grown through ...............

• A. Parthenocarpy
• B. Cuttings
• C. Grafting
• D. Layering

Answer 1

The correct option is B Cuttings

Plants can reproduce asexually and sexually. The vegetative reproduction is a means of rapid propagation, as sex cells are not involved, the progeny is identical to parent plant and the process is a type of asexual reproduction. Vegetative reproduction can be natural or artificial (cutting, layering, grafting or use of stocks). Cutting is commonly used artificial method of vegetative propagation. In cutting a cut portion of a plant generates a whole new plant as in Rose, Bougainvillea, Banana etc. Banana is a large perennial herb propagated vegetatively rather than sexually because nearly all cultivated varieties are seedless, and fruits develop parthenocarpically (in the absence of seed development). The principal method of banana propagation is division of suckers or pups which arise from the base of the main stem or from the underground corm. Large suckers are the preferred planting material. These are removed from vigorous clumps of banana trees with a spade when at least three feet tall, during warm months.
