Vernalization

Click on the flashcard to see the answer

What is vernalization?

Vernalization is the process by which exposure to a prolonged period of low temperatures leads to the flowering of certain plants.

Which hormone is believed to be involved in vernalization?

The hormone vernalin is believed to be involved in the process of vernalization.

Why is vernalization important for agricultural crops?

Vernalization is important as it ensures certain crops flower at the correct time, leading to successful reproduction and optimal yield.

Which plants commonly undergo vernalization?

Winter cereals and biennial plants like winter wheat and carrot often undergo vernalization.

How does vernalization affect the lifecycle of biennial plants?

Vernalization helps biennial plants complete their lifecycle by flowering and seeding in their second year after overwintering.

What is the difference between vernalization and photoperiodism?

Vernalization is triggered by cold, while photoperiodism is triggered by the length of day or night.

Can vernalization be artificially induced, and if so, how?

Yes, vernalization can be artificially induced by exposing plants to cold temperatures in a controlled environment.

How does vernalization contribute to plant adaptation?

Vernalization allows plants to synchronize flowering with favorable environmental conditions, enhancing survival and reproduction.

What is the role of FLC gene in vernalization?

The FLC (FLOWERING LOCUS C) gene represses flowering, and vernalization suppresses this gene's activity to promote flowering.

Which part of the plant senses the temperature changes during vernalization?

The meristematic tissue in the plant's apical meristem senses temperature changes required for vernalization.

How is vernalization undone in plants?

Vernalization in some plants can be reversed by exposing plants to warm temperatures shortly after cold exposure.

What is the historical significance of vernalization?

Vernalization was described by Trofim Lysenko in the early 20th century to increase crop yields by manipulating plant growth cycles.

Does vernalization affect genetic expression in plants?

Yes, vernalization can affect genetic expression by altering which genes are active or suppressed.

Which process intensifies the effect of vernalization on plants?

Photoperiodism can intensify the effect of vernalization by working in conjunction to regulate flowering time.

What are the modern agricultural applications of vernalization?

Modern agriculture uses vernalization to control flowering times, improving crop yields and adapting plants to different climates.
