Induction of flowering by seasonal changes in photoperiod

Induction of flowering by seasonal changes in photoperiod.

In many plants, major developmental transitions such as the initiation of flowering are synchronized to the changing seasons. Day length provides one of the environmental cues used to achieve this. We describe the molecular mechanisms that measure day length and control flowering in Arabidopsis. Also, we compare these mechanisms with those that control flowering time in rice. This comparison su...

Time to Flower, the control of flowering time by photoperiod

The transition from vegetative to reproductive phase (flowering) is one of the most important decisions a plant has to take in order to guarantee the success of its offspring. In the model plant species Arabidopsis thaliana, flowering is triggered by endogenous and environmental signals among which day length is one of the most important traits. In the so-called photoperiod pathway, the gene CO...

Effect of photoperiod and light intensity on bolting and flowering in celery

Interaction of Photoperiod & Vernalization in Flowering of Sweet Clover (Melilotus).

Melilotuis albus (alba) Desr. and M. officinalis (L.) Lam. are normally biennials flowering only in the 2nd year of growth. Under natural conditions the seeds germinate in the spring and the plants grow slowly during the first season, reaching a height of 1 to 2 feet. An enlarged storage root with a number of adventitious buds is formed in the fall and lives through the winter. In the second sp...
