Historical Biographies


Aerobiology studies of subtropical Eastern Hymalayas (Kurseong) were done for two years. A total of 32 airborne pollen types were recorded along with a few fern spores. In all 4961 pollen grains were trapped during 1981–82 and 4697 during 1982–83. The data reveals seasonal variation of pollen incidence. The incidence of tree pollen dominated over grasses and weeds. The trapped tree pollen originated fromAlnus, Betula, Engelhardtia, Quercus, Bucklandia, Acer, Salix, Ilex, Cryptomeria, Pinus, Cupressus, etc. among others, some of which are known to be allergenically significant in Kurseong. The pollen grains of weeds likeUrtica, Plantago, Cannabis, Rumex, Amaranthaceae, Chenopodiaceae etc. are also proved to be allergenically significant in Kurseong. Grass pollen grains established as highly allergenic, occurred in large amount round the year. The seasonal variation of pollen incidence was dependent mainly on variable flowering periods and climatic variations.
