Pollen is appropriately referred by some as Golden dust extremely valuable on account of their tremendous applications in science, industries and public health. No other plant part even though tiny size packed with so much information power. Similar to parts, pollen characters are varied that the classification system plants can be built up entirely basis morphology.Palynology distinct branch b...

Vochysia divergens Pohl. is a tree species used in folk medicine, landscaping and reforestation. Its occurrence recorded the Amazon, Pantanal Cerrado biomes and, despite these uses its wide distribution, studies regarding reproductive aspects are nonexistent. Thus, this research aimed to study morphology of pollen V. evaluate viability meiotic index, as well compare descriptors two natural popu...

Sporopollenin is a physically robust and chemically resilient biopolymer that comprises the outermost layer of pollen walls and is the first line of defense against harsh environmental conditions. The unique physicochemical properties of sporopollenin increasingly motivate the extraction of sporopollenin exine capsules (SECs) from pollen walls as a renewable source of organic microcapsules for ...

The tapetum is a single layer of secretory cells which encloses the anther locule and sustains pollen development and maturation. Upon apoptosis, the remnants of the tapetal cells, consisting mostly of lipids and proteins, fill the pits of the sculpted exine to form the bulk of the pollen coat. This extracellular matrix forms an impermeable barrier that protects the male gametophyte from water ...
