Plant Propagation Techniques
660 Questions
Plant propagation techniques cover both natural and artificial methods of cultivating plants, including micropropagation, tissue culture, and layering. These botanical concepts evaluate how desirable characteristics are multiplied and transferred into new plants. Questions on this topic routinely feature in the biology segment of various state and central competitive exams.

Plant Propagation Techniques Questions
-
Emasculation (removal of anther)
-
Bagging & dusting of mature pollen grains
-
Rebagging
-
All
D
Correct answer
Explanation
Artificial hybridization involves selecting desired parents, emasculating the female parent, bagging the flower to prevent contamination, dusting with desired pollen, and rebagging to ensure fertilization by the chosen pollen.
B
Correct answer
Explanation
Plant tissue culture is a well-established and widely used technique in agriculture, horticulture, and plant biotechnology.
A
Correct answer
Explanation
Micropropagation is a specific form of plant tissue culture used to rapidly produce large numbers of genetically identical plants.
C
Correct answer
Explanation
The basic stages of plant tissue culture are generally categorized as initiation, multiplication, and rooting/acclimatization.
B
Correct answer
Explanation
Totipotency is the ability of a single plant cell to divide and differentiate to produce an entire, complete new plant, not just a part.
A
Correct answer
Explanation
Plant tissue culture requires a strictly controlled environment, including light, temperature, and sterile conditions, to ensure successful growth.
A
Correct answer
Explanation
One of the primary advantages of plant tissue culture is the ability to produce large numbers of genetically identical plants (clones) rapidly.

Proximate
-
Connected
-
Patches with native plant
-
Several
C
Correct answer
Explanation
Patches containing native plants provide better habitat quality and ecological support for local wildlife than patches dominated by introduced or invasive species.
-
Patches with native plant
-
Structurally diverse
-
Large
-
Proximate
D
Correct answer
Explanation
Proximate (nearby) patches allow for easier movement and dispersal of species between habitats compared to isolated or distant patches.
-
Several
-
Proximate
-
Large
-
Patches with native plant
A
Correct answer
Explanation
Having several patches provides redundancy and increased total area, which is generally better for population stability than a single isolated patch.

Horticulture
-
pomology
-
Olericulture
-
Floriculture
B
Correct answer
Explanation
Pomology is the branch of botany that studies and cultivates fruit. Horticulture is the broader field, while Olericulture focuses on vegetables.

-
Horticulture
-
botany
C
Correct answer
Explanation
Horticulture is the art and science of cultivating plants, including fruits, vegetables, and ornamental plants. It is distinct from agriculture in its focus on garden-scale production.

Floriculture
D
Correct answer
Explanation
Floriculture is the branch of horticulture concerned with the cultivation of flowering and ornamental plants for gardens and the floral industry.
-
Hybrid
-
perennial
-
annual
-
copy
B
Correct answer
Explanation
A perennial is a plant that lives for more than two years, regrowing from the same root system each season. Annuals complete their life cycle in one year.
-
Industrialisation
-
Photosynthesis
-
Stealing
-
Sterilisation
B
Correct answer
Explanation
Photosynthesis is the biological process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose.
