About Lesson
Age and Site of Vernalization:
- Vernalization through cold treatment is very effective at the seed stage or seedling stage.
- In some cereals, even the embryos can be successfully verbalized. However, in many cold recurring species, vernalization is not effective until and unless the plant possesses at least a few leaves.
- The requirement of few leaves for effective vernalization is called ‘Ripeness to Flowering’. This suggests that plants need a certain degree of photosynthetic to respond to cold treatment.
- Probably the role of carbohydrates in vernalization is to supply some energy.
- Nevertheless, the most sensitive site which acts as the perceptive organ is the meristematic region of the shoot apex.
