Pollen Grains of Asteraceae and Analogous Echinate Grains

Pollen Grains Contour Analysis on Verification Approach

Earth’s biodiversity has been suffering the effects of human contamination, and as a result there are many species of plants and animals that are dying. Automatic recognition of pollen species by means of computer vision helps to locate specific species and through this identification, study all the diseases and predators which affect this specie, so biologist can improve methods to preserve th...

Germination Schedules of Pollen Grains: Implications for Pollen Selection.

Interaction Between Air Pollutants and Pollen Grains: The Role on the Rising Trend in Allergy

Asthma and allergic diseases cases have risen in recent decades. Plant pollen is considered as the main aeroallergen causing allergic reactions. According to available data, urban residents experience more respiratory allergies than rural residents mainly due to the interaction between chemical air pollutants and pollen grains. This interaction can occur through several mechanisms; chemical pol...

Isolation and DNA-Marker Based Genotyping of Individual Pollen Grains

Dry pollen of diploid Solanum clone 9507-04, Cotton chromosomal substitution line and Echinacea purpurea „Magnus‟ were isolated and their cells contents released in individual tubes containing water or pollen germination media, respectively.Six polymorphic markers from individual pollen grains of the diploid potato were amplified using two random amplified polymorphic DNA (RAPD) primers, i.e., ...

Morphology and viability of castor bean genotypes pollen grains

The objective of this work was to characterize the morphology and viability of the pollen of 15 genotypes of castor bean (Ricinus communis L.) and to generate information that can assist in the selection of highly promising male parents for future use in genetic improvement programs aimed at producing seeds for oil extraction. Acetolysis and scanning electron microscopy was used to characterize...
