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.

A Correct answer
Explanation

Permaculture is a design system that integrates plants, animals, and humans into a sustainable and self-sufficient ecosystem.

Multiple choice

What is the term for the practice of growing plants in water, often using a nutrient-rich solution?

  1. Hydroponics

  2. Aquaponics

  3. Aeroponics

  4. Vertical farming
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Hydroponics is a method of growing plants in a nutrient-rich water solution without the use of soil.

Multiple choice

What is the term for the young rice plants that are transplanted from the nursery to the main field?

  1. Seedlings

  2. Transplants

  3. Tillers

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

Transplants are the young rice plants that are carefully uprooted from the nursery and replanted in the main field.

Multiple choice

What is the term used to describe the practice of raising fish and plants together in a symbiotic system?

  1. Aquaculture

  2. Hydroponics

  3. Aquaponics

  4. Permaculture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Aquaponics is a sustainable food production system that combines aquaculture (raising fish) and hydroponics (growing plants in water) in a symbiotic relationship, where the waste from the fish provides nutrients for the plants, and the plants help to clean the water for the fish.

A Correct answer
Explanation

Selection is the process of selecting plants with desired traits and breeding them together to create offspring with those traits.

Multiple choice

What is the term for the practice of planting different plant species in close proximity to each other to benefit each other?

  1. Crop rotation

  2. Intercropping

  3. Companion planting

  4. Polyculture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Companion planting involves planting different plant species in close proximity to each other to benefit each other, such as by providing pest control, improving soil fertility, or attracting pollinators.

Hardening off, mulching, and winterizing are all methods of protecting plants from frost or cold weather.

Multiple choice

Which of the following is an example of a plant adaptation?

  1. Producing toxins

  2. Growing thorns

  3. Producing nectar

  4. Producing seeds
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Producing toxins is an example of a plant adaptation, as it helps the plant to defend itself against herbivores.

Multiple choice

How can MAS be combined with other breeding techniques to enhance the efficiency of plant breeding programs?

  1. MAS can be combined with genomic selection to improve the accuracy of selection

  2. MAS can be combined with speed breeding techniques to accelerate the breeding cycle

  3. MAS can be combined with phenomics to identify plants with desirable traits under field conditions

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

MAS can be combined with other breeding techniques to enhance the efficiency of plant breeding programs. For example, MAS can be combined with genomic selection to improve the accuracy of selection, with speed breeding techniques to accelerate the breeding cycle, and with phenomics to identify plants with desirable traits under field conditions. These combinations can help to develop improved crop varieties more quickly and efficiently.
