$\Huge{\mathbb{\blue{\underline{answer}}}}$

⭕Long day plants (LDP) :

➖These plants flower when the days are longer.

➖They require more than the critical duration of light to flower (usually 14-16 hours).

➖The light period is very critical in LDP plants.

➖Prolongation of the light period or a brief exposure to light during the dark period boosts flowering in these plants.

➖One usually does not find LDP plants in places where the length of a day is too short.

➖They are also called ‘Short Night Plants’.

➖Examples – spinach, radish, hibiscus etc.

⭕Short Day Plants (SDP) :

➖These plants flower when the days are shorter.

➖They need less than the critical duration of light (about 8-10 hours) and a continuous dark period (about 14-16 hours) to flower.

➖The dark period is very critical for SDP plants and has to be continuous.

➖These plants will not flower if the dark period is briefly interrupted by light.

➖SDP plants are usually not found in places where the length of a day is too long.

➖They are also called ‘Long Night Plants’.

➖Examples – soybean, tobacco, chrysanthemum etc.

⭕Day Neutral Plants (DNP) :

➖These plants do not follow this restriction of critical duration.

➖In other words, they are ‘neutral’ to the length of day or night.

➖Examples – tomatoes, pea plants, rose etc.
