A Study on the Diurnal Change of Pinus rigida Pollen Deposition in Mt. Kwan-ak

공중에 비산하는 Pinus rigida 화분의 일변화량

The amount of Pinus rigida pollen deposition was hourly measured by Durhan's pollen trap in Seoul National University during May 9∼16 o'clock and 9∼15, 1988. The peak times or pollen deposition were 9∼10 o'clock and 16∼17 o'clock. The correlation coefficients between pollen deposition and mean temperature, relative humidity, and wind speed were 0.625, -0.655 and 0.418 respectively, It is thought that pollen maturation rate is correlated with mean temperature and the pollen deposition with increasing wind speed.
