What is vernalization?
Click to flip
Vernalization is the process by which exposure to a prolonged period of low temperatures leads to the flowering of certain plants.
Click to flip
Which hormone is believed to be involved in vernalization?
Click to flip
The hormone vernalin is believed to be involved in the process of vernalization.
Click to flip
Why is vernalization important for agricultural crops?
Click to flip
Vernalization is important as it ensures certain crops flower at the correct time, leading to successful reproduction and optimal yield.
Click to flip
Which plants commonly undergo vernalization?
Click to flip
Winter cereals and biennial plants like winter wheat and carrot often undergo vernalization.
Click to flip
How does vernalization affect the lifecycle of biennial plants?
Click to flip
Vernalization helps biennial plants complete their lifecycle by flowering and seeding in their second year after overwintering.
Click to flip
What is the difference between vernalization and photoperiodism?
Click to flip
Vernalization is triggered by cold, while photoperiodism is triggered by the length of day or night.
Click to flip
Can vernalization be artificially induced, and if so, how?
Click to flip
Yes, vernalization can be artificially induced by exposing plants to cold temperatures in a controlled environment.
Click to flip
How does vernalization contribute to plant adaptation?
Click to flip
Vernalization allows plants to synchronize flowering with favorable environmental conditions, enhancing survival and reproduction.
Click to flip
What is the role of FLC gene in vernalization?
Click to flip
The FLC (FLOWERING LOCUS C) gene represses flowering, and vernalization suppresses this gene's activity to promote flowering.
Click to flip
Which part of the plant senses the temperature changes during vernalization?
Click to flip
The meristematic tissue in the plant's apical meristem senses temperature changes required for vernalization.
Click to flip
How is vernalization undone in plants?
Click to flip
Vernalization in some plants can be reversed by exposing plants to warm temperatures shortly after cold exposure.
Click to flip
What is the historical significance of vernalization?
Click to flip
Vernalization was described by Trofim Lysenko in the early 20th century to increase crop yields by manipulating plant growth cycles.
Click to flip
Does vernalization affect genetic expression in plants?
Click to flip
Yes, vernalization can affect genetic expression by altering which genes are active or suppressed.
Click to flip
Which process intensifies the effect of vernalization on plants?
Click to flip
Photoperiodism can intensify the effect of vernalization by working in conjunction to regulate flowering time.
Click to flip
What are the modern agricultural applications of vernalization?
Click to flip
Modern agriculture uses vernalization to control flowering times, improving crop yields and adapting plants to different climates.
