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.

Explanation
This is the correct option. Only paddies, tomatoes and chillies are grown by the method of transplantation.
-
the runners
-
offset
-
stolon
-
sucker
-
cladophyll
A
Correct answer
Explanation
Runners are horizontally oriented stems that grow along the soil surface. Their function is vegetative production. For example: number of grasses have stolons. Strawberries are normally propagated asexually by two different methods: runners (stolons) and crown division.

B
Correct answer
Explanation
Unorganised and undifferentiated mass of tissue is used in callus culture.
-
Apical meristem tissue culture
-
Ovary tissue culture
-
Nucellar tissue culture
-
Pollen culture
D
Correct answer
Explanation
Pollen culture is used to produce haploid plants.
-
Nucellar tissue helps in formation of tap root system.
-
Nucellar seedlings are vigorous.
-
Nucellar seedlings are free from diseases.
-
All of the above
D
Correct answer
Explanation
Nucellar tissue helps in formation of tap root system. Nucellar seedlings are free from diseases. Nucellar seedlings are vigorous.
-
Embryo culture
-
Ovary culture
-
Pollen culture

Apical meristem culture
B
Correct answer
Explanation
Ovary culture is used to improve quality of fruits.
-
25+/-2 degree centigrade dark

25+/-2 degree centigrade bright light
-
25+/-2 degree centigrade dim light
-
35+/-2 degree centigrade dim light
C
Correct answer
Explanation
25+/-2 degree centigrade in dim light is the optimum condition required for protoplast regeneration.
-
callus culture
-
organ culture
-
somatic hybridisation
-
single cell culture
C
Correct answer
Explanation
Somatic hybridisation produces hybrids by completely eliminating sexual processes.
-

A
Correct answer
Explanation
The ability of the component cells of callus to form a whole plant is known as redifferentiation.

-
dividing clumps for pseudo bulbs
-
cuttings
-
seed and tissue culture
-
All the above
D
Correct answer
Explanation
Orchids can be propagated through multiple methods including dividing clumps with pseudobulbs, cuttings, and seed and tissue culture. Different orchid species and growing conditions determine which method works best. The use of multiple techniques allows for flexibility in commercial and amateur orchid cultivation.
