|
2. It prepares the plants for flowering rather than inducing flowering.
|
|
3. It is a florigen mediated response.
|
3. It is a response mediated by vernalin which is induces the florigen synthesis.
|
|
4. The effects of photoperiodism cannot be reversed. Only the flowering response produced by the red light can be reversed by the applying the far red radiation.
|
4. The effects of vernalization that is low temperature treatment can be reversed by the exposure to high temperature.
|
|
5. The stimulus is perceived by the young leaves.
|
5. The stimulus is perceived by the entire shoot apical meristem.
