Learn about the process of pollen germination, the factors that affect it, and the types of fertilization based on the entry of pollen tubes into the ovule. Find out the difference between pollen and seed, pollen and pollen grain, and pollen and self-incompatibility.
A chapter from a book on the embryology of angiosperms, covering the mechanisms and molecules involved in pollen tube development and guidance. Learn about the cytoplasmic rearrangements, the cell-cell interactions, the cytoskeleton and the exocytosis of pollen tubes.
Learn about pollen germination and tube development in various plant species and their responses to environmental factors. Explore chapters and articles on boron, brassinosteroids, proteomics, and saffron.
Explain cross-pollination and the ways in which it takes place. Describe the process that leads to the development of a seed. Define double fertilization. In angiosperms, pollination is defined as the placement or transfer of pollen from the anther to the stigma of the same flower or another flower.
Many aspects of Angiosperm pollen germination and tube growth are discussed including mechanisms of dehydration and rehydration, in vitro germination, pollen coat compounds, the dynamic involvement of cytoskeletal elements (actin, microtubules), calcium ion fluxes, extracellular matrix elements (stylar arabinogalactan proteins), and control ...
Oct 1, 2023 · Pollen germination is a prerequisite for double fertilization of flowering plants. A comprehensive understanding of the structural and molecular basis of pollen germination holds great potential for crop yield improvement.
Jan 1, 2010 · Pollen grains transfer from a quiescent state to a germination program when they land on the stigma. Successful landing and adhesion is the essential first step to initiate an intimate mating dialogue between both male and female gametophytes.
