Anthesis and pollen release: anthesis and pollen release of some plants of west bengal, india

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