Ankita161:
please can you explain me
You can understand this thing by reading this paragraph of class 12 cbse biology book
page 251
as I am unable to send the pics 0f the pages , so please wait for 3 days after that I will type the whole paragraph for you...but as I am a bit busy now I will only be able to type the answer after 3 days
here is your answer I am typing a para from the 11 th ncert bio book hope it helps
It has been observed that some plants require a periodic exposure to light to induce flowering . It is also seen that such plants are able to measure the duration of exposure to light . For example , some plants require the exposure to light for a period exceeding a well defined critical duration
While others must be exposed to light
for a period less than this critical duration before the flowering is initiated in them . The former group of plants are called long day plants while the latter ones are termed as short day plants. The critical duration is different for different plants . There are many plants however , where there os no correlationvbetween exposure to light duration and inducation of flowering response such plants are called day neutral plants.
It is also known that not only the duration of light period but that the duration of dark period os also of equal importance . Hence 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 and night is termed as photoperiol
sorry the word was wrongly typed it would be photoperiodism
