Abstract
This study compares the accuracy of various pollen counting methods in order to find an optimum sample size for the study of air-borne pollen obtained from Burkard seven-day volumetric recording trap in Taiwan. Pollen species counts and estimates of pollen quantity obtained using various sample sizes are compared. The coefficients of variance of various sample sizes and diurnal variations in pollen concentration are also analyzed. The results show that a minimum sampling of one transverse traverse per hour or every two hours from trapping tape is suitable for the estimation of the total pollen quantity collected an a day and for the study of diurnal variations in pollen concentration at a collecting station.
