Concept explainers
To determine: The percentage of the plant flower in the given figure when the day length is 10 hours and the night length is 14 hours.
Introduction: Photoperiodism is the behavioral response shown by the organisms, especially plant species, to the length of the day or night. Each plant has its characteristic photoperiod that is very essential for its normal growth and reproduction.
