Abstract:

A study of the airborne pollen grains in Nsukka, Nigeria, has been carried out at two different sampling heights (1.8 m and 15 m) from February 1993 to January 1994. Twenty-six plant families (40 genera) were identified at the lower sampling height, whilst thirty-eight families (58 genera) were identified at the height of 15 m. A total of nine and eighteen fern spore types were observed at 1.80 m and 15 m, respectively. The quantitative results indicate that the number of pollen observed at 15 m sampling height was statistically different (p Casuarina equisetifolia, Milicia excelsa, Elaeis guineensis, Celtis integrifolia, Alchornea cordifolia , Amaranthaceae/Chenopodiaceae, Combretaceae/Melastomataceae, Nephrolepis biserrata, Thelypteris totta, and Dryopteris spp.
