Pollen analysis at INQUA

Pollen nightmare: elevated airborne pollen levels at night

High airborne pollen concentrations are generally associated with daylight hours when it is sunny and warm and plants release pollen into the air (Alcázar et al. 1999; Dahl et al. 2013). In contrast, cooler nighttime periods are usually considered to be the time of low-allergy risk. This opinion is often reflected in pollen allergy avoidance strategies presented by the media, where the most com...

Comparative proteomic analysis of Arabidopsis mature pollen and germinated pollen.

Proteomic analysis was applied to generating the map of Arabidopsis mature pollen proteins and analyzing the differentially expressed proteins that are potentially involved in the regulation of Arabidopsis pollen germination. By applying 2-D electrophoresis and silver staining, we resolved 499 and 494 protein spots from protein samples extracted from pollen grains and pollen tubes, respectively...

Pollen Analysis: Not Just a Qualitative Tool

Pollen analysis is seen as a largely qualitative method, but recent developments in analytical techniques, technologically and theoretically, have directed a move towards a greater use of quantitative interpretation. Use of these new methods allows more detailed information to be obtained from pollen data and in turn widens the scope for use of this technique. It is often assumed that pollen an...

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...
