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 [...]
In this article we will discuss about:- 1. Subject-Matter of Floral Induction 2. Changes in Metabolism in Leaves Associated with Floral Induction 3. Floral Induction, Determination and Specification in Arabidopsis Determination Experiments 4. Control of Flower Primordium Specification by LEAFY and APETALAI/CAULI FLOWER 6. Interactions between LFY, API and TERMINAL FLOWERI (TFLI) during the Transition to Flowering. Subject-Matter of Floral [...]
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 is also possible to maintain [...]
