In this article we will discuss about:- 1. Pollen Wall Adaptations 2. Harmomegathic Adaptation 3. Adaptation to Habitat 4. Adaptation to Mode of Pollination The Sporoderm structure, its chemical constituents and the diverse aperture types of pollen grains, has possibly developed as a need to adaptation in response to their respective habitats and mode of pollination. It has been seen [...]
The following points highlight the nine main chemical constituents of pollen. The chemical constituents are: 1. Major Metabolites 2. Carbohydrates 3. Mineral Content 4. Callose 5. Organic Acids 6. Amino Acids 7. Pigments 8. Vitamins 9. Hormones and Steroids. Chemical Constituent # 1. Major Metabolites: The metabolites like carbohydrates, proteins and lipids vary considerably in pollen due to (a) the [...]
The term aerobiology came into use during 1930 for the studies of airspora like airborne fungal spores, pollen grains and other microorganisms. Jacobs (1951) elaborated the term to include dispersion of insect populations, fungal spores, pollen grains, bacteria and viruses. In fact, all forms of life belonging to both plants and animals which become airborne are transported partly or wholly [...]
