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

Multiple choice

Consider the following plants:1. Jasmine

  1. Sugarcane
  2. Turmeric Which of the above is/are propagated by vegetative method?

  1. 1 only

  2. 1 and 2 only

  3. 2 and 3 only

  4. 1, 2 and 3
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All three plants are commonly propagated vegetatively: Jasmine through stem cuttings, Sugarcane through stem sections (setts) with nodes, and Turmeric through rhizome division. Vegetative propagation produces clones of the parent plant and is faster than seed propagation.

Multiple choice

The science of growing vegetables, flowers and fruits for commercial use is called ________.

  1. farming

  2. viticulture

  3. agriculture

  4. horticulture
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Horticulture is the science and art of growing fruits, vegetables, flowers, and ornamental plants for commercial use. Agriculture is broader (field crops), viticulture specifically covers grapes, and farming is a general term. Horticulture comes from Latin 'hortus' (garden).

Multiple choice

If floriculture is the cultivation of flowers, horticulture is the

  1. practice of garden cultivation, particularly of fruits

  2. rearing of fish

  3. rearing of ducks

  4. None of these

A Correct answer
Explanation

Horticulture is the branch of agriculture that deals with the art, science, technology and business of growing plants. It includes the cultivation of medicinal plants, fruits, vegetables, nuts, seeds, herbs, sprouts, mushrooms, algae, flowers, seaweeds and non-food crops, such as grass and ornamental trees and plants.

Multiple choice

________ is a practice adopted by the scientists to evolve new varieties of plants.

  1. Post fertilization

  2. Artificial pollination

  3. Double fertilization

  4. Fertilization stage
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Artificial pollination (also called hand pollination or controlled pollination) is a technique used by plant breeders to deliberately cross-pollinate specific plants to create new varieties with desired traits. Post-fertilization and double fertilization are biological processes, not breeding practices.

Multiple choice

Which of the following is not an artificial method of vegetative propagation?

  1. Cutting

  2. Layering

  3. Grafting

  4. Tissue culture

  5. Separation
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is the correct option. Plant organs such as bulbs, cloves tubers can be used in plant propagation as planting materials or propagules. To use them, they are separated from the parent plant in which the propagation method is called separation. This is a natural method of vegetative propagation.

Multiple choice

Which of the following is/are the advantage(s) of vegetative reproduction?

  1. Seedless plants can be raised.

  2. Plants produced are identical copies of parent plants.

  3. Plants like banana, sugarcane can be grown by this method.

  4. All of the above

  5. It is a slow and expansive method.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

This is the correct option. All of the above are the advantages of vegetative reproduction. It is an easier, rapid and less expansive method.
