Abstract
An investigation on airborne pollen during 1983 at Nankang, Taipei was undertaken. Pollen grains and fern spores encountered within an area of 3.24 cm2 on a trap slide were counted and identified to genus level. The results show that the highest concentration of airborne pollen grains was found in the spring with a number of tree pollen: Pinus, Juniperus-Cunninghamia, Myrica, Broussonetia, Celtis, Ligustrum, Bischofia, Podocarpus, Casuarina, Trema, Acacia confusa and Mallotus japonicus. Salix and Morus flower at the end of the winter or at the beginning of the spring. In the summer, many fern spores, namely Alsophila, Dicranopteris, Pteridium, Nephrolepis and Lepisorus and some weeds pollen, like Chenopodiaceae were recorded, while in the autumn Mallotus paniculatus, Alnus, Melaleuca and Gramineae were of dominant species. Some weed pollen of Artemisia, Ambrosia and Humulus were also found in the autumn. In the winter the dominant pollen species were Gramineae. A pollon calender showing the occuring pollen and fern spore species during a year is demonstrated.
