title: [Pollen dispersion of Japanese cedar and Japanese cypress in Kagawa Medical University of Kagawa Prefecture].
abstract: We installed the Durham sampler on the roof (27.4 m on the ground) of Kagawa Medical University in 1989 to survey pollen dispersion in Kagawa prefecture and have investigated the pollen survey from 1989 to 2001. We examined the correlation between the annual variations in the pollen counts of Japanese cedar (Cryptomeria japonica) and Cupressaceae, mainly Japanese cypress (Chamaecyparis obtusa) and annual changes in meteorological conditions. The sum of these pollen counts correlated with the highest temperature from 11 July to 10 August in Kagawa prefecture. However, it is difficult to determine the pollen dispersion only based on meteorological factors. Other factors giving influences on the pollen dispersion need to be further analyzed in the future.
