Effect of daily duration of light and dark periods on growth and development of plants especially on flowering is called
1 Vernalisation
2 Photoperiodism
3 Phototaxis
4 Both 1 and 2
Explanation:
It can be said that flowering in certain plants depends not only on a combination of light and dark exposures but also their relative durations. This response of plants to periods of day/night is termed photoperiodism.

Through their effect on plant growth regulators, what do the temperature and light control in plants?
1 Fruit elongation
2 Apical dominance
3 Flowering
4 Closure of stomata
Explanation:
Light and temperature affects flowering in plants in various ways, the effects of photoperiods helps in flowering viz Long day plants, Short day plants and Day neutral plants. Vernalisation is also dependant on low temperature and it induces flowering.

Name the term used for the response of plants to periods of day/night?
1 Photoperiodism
2 Aestivation
3 Vernalization
4 Dormancy
Explanation:
Photoperiodism is the term used for the response of plants to periods of day/night.

Day neutral plants
1 Show no flowering in any photoperiod
2 Show loss of activity during day time
3 Have no correlation between exposure to light duration and induction of flowering response
4 None of the above
Explanation:
The critical duration is different for different plants. There are many plants, however, where there is no such correlation between exposure to light duration and induction of flowering response; such plants are called day-neutral plants.
