Answer 1

The correct option is D All of the above

Plants requiring vernalization are confined to temperate and polar regions. Vernalization induces rapid development. Vernalization reduces the interval between the sowing and flowering. Winter varieties of cereals can be made to behave as spring varieties by vernalization. Vernalization is the acquisition of a plant's ability to flower in the spring by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually flower. Vernalization can also refer to herbal plants requiring a cold dormancy to produce new shoots and leaves.
