Abstract

Abstract The pattern and quantum of daily pollen release of thirty five plants of southern West Bengal were studied by counting their nature and time of anther dehiscence in one hour time interval in relation to meteorological condition. The results have been correlated with the atmospheric concentration of pollen grains in their surrounding environment by using rotorod sampler. The duration of pollen release varies from 2–12 h with a peak of 4–10 h. This result corroborates with the concentration of atmospheric pollen grains. It is noticed that pollen release intensity is high in short duration and vice versa. The variation of pollen release has also been observed in each species when meteorological condition gets changed abruptly.
