Plant Propagation Techniques
591 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
-
Mango and apricot
-
Avacado and beetroot
-
Rose and jasmine
-
Broad bean and broccoli
C
Correct answer
Explanation
The main examples are banana, pineapple, rose, jasmine, etc. in which vegetative propagation is practised.
-
Cross pollination
-
Cutting
-
Layering
-
Grafting
A
Correct answer
Explanation
Cross pollination is not a type of vegetative propagation.
-
Grafting
-
Joining
-
Layering
-
Cutting
A
Correct answer
Explanation
Grafting is the method in which two plants are joined together in such a way that they unite and grow as one plant.
-
roots
-
leaves
-
stems and buds
-
All the above
D
Correct answer
Explanation
Vegetative propagation can occur through various plant parts, including roots, stems, and leaves, which are all capable of regenerating a new plant.
-
natural
-
synthetic
-
non synthetic
-
All the above
B
Correct answer
Explanation
Tissue culture techniques allow for the production of synthetic seeds, which are encapsulated somatic embryos used for plant propagation.
-
Tapioca
-
Asparagus
-
Dahila
-
All the above
D
Correct answer
Explanation
Tapioca, Asparagus, and Dahlia are all examples of plants that can be propagated through their roots (tuberous roots).
-
Bryophyllum
-
Kalanchoe
-
Both 1 and 2
-
None of the above
B
Correct answer
Explanation
Kalanchoe plants are propagated through roots and Bryophyllum reproduce by vegetative propagation through leaves.
-
strong
-
week
-
small
-
branched
-
stem cutting
-
root cutting
-
layering
-
All the above
-
bud grafting and crown grafting
-
approach grafting and tongue grafting
-
wedge grafting and crown grafting
-
All the above
D
Correct answer
Explanation
Grafting techniques include bud, crown, approach, tongue, and wedge grafting. Since all listed pairs are valid types, 'All the above' is correct.
-
cutting
-
propagating
-
layering
-
All the above
D
Correct answer
Explanation
Cutting and layering are both well-known artificial methods of vegetative propagation. Since multiple options are correct, 'All the above' is the intended answer.
-
parthenogenesis
-
sporophytic budding
-
polyembryony and apomixes
-
All the above
D
Correct answer
Explanation
Parthenogenesis, sporophytic budding, polyembryony, and apomixis are all recognized special or asexual modes of plant reproduction.
-
mango
-
apple
-
citrus
-
All the above
D
Correct answer
Explanation
Grafting is a widely used horticultural technique for propagating many fruit trees, including mango, apple, and citrus.
-
a and b
-
b and c
-
a and c
-
a, b and c
-
only c
C
Correct answer
Explanation
This is the correct answer as both bryophyllum and cactus can be grown with vegetative propagation. Bryophyllum plants can be reproduced by vegetative propagation by using either a piece of its stem or leaves. Money plant can be grown by vegetative propagation by using a piece of its stem.
-
Budding
-
Regeneration
-
Fragmentation
-
Fission
-
Micropropagation
E
Correct answer
Explanation
This is correct. Micropropagation is the tissue culture technique for plant propagation in which a tissue is taken from a plant and grown in a laboratory to produce plantlets that are genetically identical.
