Question

Induction of flowering by low temperature treatment is known as ____.

• A. Vernalization
• B. Cryobiology
• C. Photoperiodism
• D. Pruning

Answer 1

The correct option is A Vernalization

Vernalization is the process by which prolonged exposure to cold temperatures promotes flowering. It is an important adaptation of plants growing in regions where harsh winters are followed by relatively short growing seasons. Vernalization prevents flowering in the shorter days of autumn and ensures that flowering occurs in the warmer days of spring and summer, allowing sufficient time for seed development before the onset of the next winter.

Cryobiology is the study of biological material or systems like proteins, cells, tissues, organs, or whole organisms at temperatures below normal. Materials or systems studied may include proteins, cells, tissues, organs, or whole organisms.

Photoperiodism describes a plant's ability to flower in response to changes in the photoperiod, the relative lengths of day and night.

Pruning is a horticultural practice that alters the form and growth of a plant.

So, the correct answer is 'Vernalization'
