POLLEN‐POLLEN AND POLLEN‐STYLE INTERACTIONS DURING POLLEN TUBE GROWTH IN ERYTHRONIUM GRANDIFLORUM (LILIACEAE)

American Journal of Botany, 1990
Using pairs of pollen donors, I analyzed the growth of pollen tubes growing in different channels of the same style in Erythronium grandiflorum. After 24 hr the length of pollen tubes of randomly selected pollen donors was affected by the presence of other donors.

Pollen and sub-pollen particles: External interactions shaping the allergic potential of pollen

Science of The Total Environment
Pollen allergies, such as allergic rhinitis, are triggered by exposure to airborne pollen. They are a considerable global health burden, with their numbers expected to rise in the coming decades due to the advent of climate change and air pollution. The relationships that exist between pollens, meteorological, and environmental conditions are complex ...
