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 well as temperature, etc. The [...]
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 response. Vernalization is also known [...]
In this article we will discuss about:- 1. Definition of Vernalization 2. Site of Vernalization 3. Nature of Vernalization Process 4. Application. Definition of Vernalization: The precise definition of vernalization is not universally accepted. The term is best defined as the specific promotion of flowering by a cold treatment given to the imbibed seed or young plant. In certain seeds, [...]
