Flash of light in dark inhibits flowering in
A. SDP
B. LDP
C. LSDP
D. DNP

Answer 1

Hint: Flash of light in dark occurs in those plants that begin flowering when days are shorter. Then the days are length.these plants required long periods of darkness and just a short period of light in order to flower.

Complete answer: SDP - SDP refers to short day plants. These plants are known to us only when days are shorter. These plants need a big day duration that lasts between 7 to 8 hours and they need continuous dark periods that range between 16 to 17 hours. Examples of these plants are soya bean, tobacco etc.
LDP - LDP refers to the long day plants these plants occur when days are longer. This latter is completely opposite from sdp. as they need containers daylight of 16 to 18 hours and on the other hand they need very less period of darkness that may range between 6 to 8 hours.
LSDP - it is known as low sulphur diesel plants. These plants consume very less amount of Sulphur. Distances are also known as photoperiodism. These plants are very beautiful at a glance. They release great fragrance.
DNP - These plants are known as day neutral plants. These plants do not need to complete daylight nor they need complete darkness. However these plants flower mostly In the neutral time when there is no completely dark and no completely daytime.
So, from the above discussion we can conclude that the correct answer is option A.

Note: Given are four forms when plants flower. SDP flowers during night, ldp flowers during daytime. DNP flowers at a neutral time that is not daytime nor completely dark. LSDP plants give sweet fragrance.
