Vernalization is the process of
1. flower induction by high temperature treatment
2. inhabitation of flowering by low temperature treatment
3. flower induction by light treatment
4. acceleration of the ability of a plant to produce flowers by chilling treatment
Induction of flowering by low temperature in plants is
1. cryobiology
2. vernalization
3. phototropism
4. pruning.
Vernalisation is subjected to plants growing in ?
(1) tropical
(2) sub tropical areas
(3) temperate areas
(4) hot region/arctic region
Which one plant movement is unidirectional?
(1) Phototaxis
(2) Chemotaxis
(3) Both (a) and (b)
(4) Thigmotrophism
Flowering can be affected in certain plants
1. by quantitative exposure to low temperature
2. by qualitative exposure to low temperature
3. Both A and B
4. It does not depend on low temperature exposure
Vernalisation prevents
1. Precocious reproductive development late in growing season
2. Late reproductive development
3. Flowering
4. Fruiting
Vernalisation
(1) Disables the plant to have fruits
(2) Enables the plants to have fruits
(3) Enables the plants to have sufficient time to reach maturity
(4) Brings senescence
Vernalisation refers to
(1) The promotion of flowering by a period of high temperature
(2) The inhibition of flowering by a period of low temperature
(3) The promotion of flowering by a period of low temperature
(4) The inhibition of flowering by a period of high temperature
