[relationships between atmospheric sugi (japanese cedar)-pollen counts and indices of climatic conditions].atmospheric pollen surveys have been conducted using durham's standard sampler for 12 years in toyama prefecture. the relationships between sugi (japanese cedar, cryptomeria japonica d. don) pollen and some indices of climatic conditions were analyzed. the results were as follows: 1. total pollen counts showed a tendency to increase for 12 years, although the variation of the count was relatively large. 2. significant correlations were found between pollen counts and some indices of the climatic ...19958520050
[relationships between the pollen productions in sugi (cryptomeria japonica d. don) forests and the patterns of atmospheric scattering pollens in toyama prefecture--the example of toyama prefecture in 1990].we investigated the geographical distribution of sugi (cryptomeria japonica d. don) forests and the male flower-setting conditions of them in toyama prefecture. the relationships between our findings and the atmospheric pollen scattering patterns were also studied. the results were as follows. 1. atmospheric pollen counts and their scattering patterns were fairly easily explained by the geographical distribution of 30-year old sugi forests, the male flower-setting conditions and the first day po ...19911958135
