In this article we will discuss about:- 1. Meaning of Photoperiod 2. Photoperiodic Response Groups 3. Photoinductive Cycles 4. Genetic Approach 5. Flowering Hormone. Subject-Matter of Photoperiod: Two American plant physiologists, W.W. Garner and H.A. Allard (1920) while working at the USA department of Agriculture Research Laboratories at Beltsville, Maryland made observations that tobacco variety, Maryland Mammoth, grew vegetatively in [...]
In this article we will discuss about:- 1. Recognition and Rejection of Incompatibility 2. Biological Significance of Incompatibility. Recognition and Rejection of Incompatibility: The rejection of 'self’ in self-incompatibility system implies the existence of a recognition event. In fact pollen-stigma interaction is an interesting example of cell recognition in flowering plants. Both self-and cross-pollinations are the outcome of such interactions [...]
