Pollen viability and pollen vigor

Theoretical and Applied Genetics, 1991
Investigations were carried out to correlate pollen viability, assessed on the basis of a fluorochromatic reaction (FCR) test, with pollen vigor, assessed on the basis of the time taken for in vitro germination in pollen grains subjected to high humidity (>95% RH) and temperature (38 °C) or storage stress of Nicotiana tabacum, Agave sp., Tradescantia ...

Studies on pollen and pollen extracts

Journal of Allergy, 1931
Summary Skin sensitivity to pollen extracts has been demonstrated in actively immunized rabbits using trypan blue as an aid, after the method of Ramsdell. The reaction is specific, and is more delicate than the precipitin test as indication of an immune response of the animal.

Sharing the pollen [PDF]

Nature Reviews Microbiology, 2021
This study shows that co-existence of the four Lactobacillus species in the gut of the honey bee is mainly dependent on the pollen-rich diet of the host, and mediated by the specialization of the gut symbionts towards distinct pollen-derived nutrients.
