In this article we will discuss about the growth regulators in flowering. Phytohormones and Flower Initiation: In recent years considerable information has accumulated to demonstrate that growth regulations change the flowering behaviour of several plant species. Further the effect of growth regulators varies with the plant species, its age, concentration of growth regulators employed as […]

The following points highlight the two main approaches of photoperiodic time measurement. Approach # 1. The Conception of Physiological Clock of Erwin Bunning: This is also known as biological clock or oscillating clock. Bunning performed several experiments in Kalanchoeblossfeldiana. In this species the petals open in the morning and close down in the evening. It […]
Vernalization (With Experiments) | Plant Physiology
Article Shared by
Vernalization has multiple interactions with photoperiodism. Thus, a cold requirement for flowering appears to be associated with a specific photoperiod. The most well quoted instance is that of need for vernalization and LD which leads to flowering in late spring or early summer. However, a cold requirement may also be accompanied by a SD photoperiodic […]
