how photo period affects plants during photosynthesis
Answers
Phototropism, plant growth towards or away from light, and photoperiodism, regulation of flowering and other developmental transitions by day/night length.
Answer:
Protected crops are often grown in a period of the year when natural light is not sufficient for growth. It is then necessary to lengthen natural short days with supplementary light. Such a treatment may be considered sensu latoas a photoperiodic one, but, as the daily quantity of energy is concerned, there is evidently a direct effect on photosynthesis. For the physiologist, on the other hand, a photoperiodic effect sensu stricto is a given evolution of phytochrome photoequilibrium at night. We present here examples illustrating the two meanings of the concept and the response of photosynthesis.
