Vegetative propagation
The syllabus for Biology in the AIIMS entrance exam may vary slightly from year to year, but generally, it covers topics from the CBSE (Central Board of Secondary Education) curriculum for Class 11 and Class 12. One of the topics included in the syllabus is vegetative propagation. Here’s an overview of the concept:
Vegetative propagation refers to the asexual reproduction in plants where new individuals are produced from vegetative parts of a parent plant, such as stems, leaves, and roots. This process allows plants to reproduce without the involvement of seeds or spores.
The following are the key aspects of vegetative propagation that you should be familiar with:
- Natural methods of vegetative propagation:
- Runners: Special horizontal stems called runners or stolons grow above the ground, and new plants form at their nodes. Examples include strawberry plants.
- Rhizomes: Underground horizontal stems called rhizomes produce new shoots and roots at their nodes. Examples include ginger and ferns.
- Tubers: Swollen underground stems called tubers store food and can develop into new plants. Examples include potatoes.
- Bulbs: Underground modified leaves called bulbs contain an apical bud that gives rise to a new plant. Examples include onion and garlic.
- Corms: Swollen underground stems called corms give rise to new plants. Examples include gladiolus.
- Artificial methods of vegetative propagation:
- Cutting: A piece of a stem, root, or leaf is cut and planted in suitable conditions to form a new plant. Examples include rose and sugarcane.
- Grafting: A part of one plant (scion) is attached to the stem of another plant (stock) in such a way that they grow together as a single plant. Examples include fruit trees and roses.
- Layering: A branch is bent and partially buried in the soil while still attached to the parent plant. The buried part develops roots and can be separated to form a new plant. Examples include jasmine and blackberries.
- Tissue culture: In vitro propagation of plants from a small piece of tissue, such as a leaf or meristem, in a sterile nutrient medium. This method allows mass production of plants with desired traits.
It’s important to study the specific examples and techniques associated with each method of vegetative propagation. Understanding the advantages, disadvantages, and applications of vegetative propagation in horticulture, agriculture, and conservation is also essential.
Remember to refer to the official AIIMS syllabus and study materials to ensure you cover all the necessary topics for the exam.

Case Study on AIIMS-SYLLABUS Biology syllabus Vegetative propagation
The Impact of Vegetative Propagation on Crop Yield
Introduction:
Vegetative propagation plays a significant role in agricultural practices and crop production. It allows farmers to reproduce plants with desirable traits and characteristics, ensuring a consistent and high-quality yield. This case study focuses on the impact of vegetative propagation techniques on crop yield and highlights their practical applications.
Background:
A group of farmers in a rural agricultural region relies heavily on a particular crop, the banana, for their livelihood. However, they face challenges due to the susceptibility of bananas to diseases and pests. Additionally, the traditional method of banana propagation through seeds leads to genetic variations and inconsistent crop quality.
Objective:
The objective of this case study is to evaluate the impact of vegetative propagation techniques, specifically through tissue culture, on banana crop yield and disease resistance.
Methods:
Selection of Parent Plant: Healthy and disease-resistant banana plants were selected as parent plants for vegetative propagation.
Tissue Culture Technique:
a. Collection of Explants: Small sections of the parent plant’s shoot tip, called explants, were collected under sterile conditions.
b. Sterilization: The explants were treated with disinfectants to eliminate any microbial contamination.
c. Nutrient Medium: The explants were placed in a nutrient medium containing specific growth hormones to stimulate their growth and development.
d. Subculture: As the explants multiplied and formed small plantlets, they were transferred to fresh nutrient media to promote their growth.
e. Acclimatization: Once the plantlets developed roots and shoots, they were gradually exposed to the external environment to adapt to natural conditions.
Results:
Disease Resistance: The banana plants obtained through tissue culture showed enhanced resistance to common diseases that affected the traditional seed-propagated bananas. This was attributed to the selection of disease-resistant parent plants.
Increased Yield: The vegetatively propagated banana plants exhibited consistent growth patterns and superior fruit quality. The farmers reported a significant increase in crop yield compared to the traditionally propagated bananas.
Conclusion:
The case study demonstrated the positive impact of vegetative propagation, specifically through tissue culture, on banana crop yield and disease resistance. By selecting disease-resistant parent plants and using advanced propagation techniques, the farmers were able to overcome the challenges associated with traditional seed propagation. The adoption of vegetative propagation methods allowed for consistent, high-quality banana production, resulting in improved economic outcomes for the farmers.
This case study highlights the practical application of vegetative propagation techniques, emphasizing their significance in modern agricultural practices. It also showcases the importance of understanding the biology and techniques of vegetative propagation, as it directly influences crop productivity and sustainability.
Please note that this is a fictional case study created to illustrate the potential impact of vegetative propagation. In real-world scenarios, the results and outcomes may vary based on various factors, including crop type, environmental conditions, and specific techniques employed.
