Which of the following plants requires vernalisation?
Rice
Winter Wheat
Cotton
Maize
The site of perception of low temperature stimulus during vernalisation is:
Root apex
Shoot apex
Leaves
Flowers
Vernalisation prevents precocious reproductive development late in the growing season, ensuring that the plant:
Flowers in the autumn
Flowers in the winter
Flowers in the spring
Remains vegetative
Which of these is NOT a benefit of vernalisation?
Ensures flowering in favorable conditions
Increases yield
Improves crop quality
Increases seed dormancy
If a winter wheat variety is not exposed to cold temperatures, it will:
Flower earlier
Flower later
Likely not flower
Produce more seeds
The effective temperature range for vernalisation in most winter cereals is:
15°C to 25°C
0°C to 10°C
-5°C to -15°C
20°C to 30°C
Vernalisation is perceived by which part of the plant?
Leaves
Roots
Shoot apex
Flowers
Which plant group typically requires vernalisation for flowering?
Tropical annuals
Biennials
Perennials that flower throughout the year
Plants with short life cycles
What is the significance of vernalisation in crop plants like winter wheat?
Allows flowering throughout the year
Prevents early flowering during unfavorable conditions
Ensures flowering in the spring after the winter season
Promotes vegetative growth during winter
A plant requiring vernalisation was grown in a warm greenhouse. Which of the following would be the most likely outcome?
The plant would flower earlier than usual.
The plant would flower at the normal time.
The plant would show delayed or no flowering.
The plant's vegetative growth would be stunted.
