Q1. Define propagation. Explain the different methods of asexual propagation.
- Propagation creates new plants from existing ones, categorized into sexual (seeds) and asexual (vegetative parts).
- Asexual propagation (vegetative propagation) uses single parent's vegetative parts, producing genetically identical 'true-to-type' clones.
- Cuttings involve rooting detached plant parts like stems, leaves, or roots to form new plants (e.g., rose stem cuttings).
- Layering induces root formation on a stem while it remains attached to the parent plant, then detached (e.g., air layering litchi).
Answer: Propagation refers to the process of creating new plants from existing ones. This fundamental practice in horticulture ensures the multiplication and continuity of plant species, whether for food production, ornamental purposes, or conservation. It can broadly be divided into two main categories: sexual propagation (using seeds) and asexual propagation (using vegetative parts). Asexual propagation, also known as vegetative propagation, involves producing new plants from the vegetative parts of...
