Classify and explain the plants based on photoperiodism.

Explanation

i. Long day plants: The plants that required long critical day length for flowering are called long day plants or short night plant. Example : Pea, Barley and Oats.
ii. Short long day plants: These are long day plants but should be exposed to short day lengths during early period of growth for flowering. Example : Wheat and Rye.
iii. Short day plants : The plants that require a short critical day length for flowering are celled short day plants or long night plants. Example : Tobacco, Cocklebur, Soybean, Rice and Chrysamthemum.
iv. Long short day plants : These are actually short-day plants but they have to be exposed to long days during their early periods of growth for flowering. Example : Some species of Bryophyllum and Night jasmine.
v. Intermediate day plants : These require a photoperiod between long day and short day for flowering . Example : Sugercane and Coleus.
vi. Day neutral plants: There are a number of plants which can flower in all possible photoperiods. They are also called photo neutrals or indeterminate plants. Example : Potato, Rhododendron, Tomato and Cotton.
