Abstract
In order to estimate the identity and source of the grass species component of airborne pollen and its constituents, a vegetation analysis was conducted in the central part of Morioka city during early April and early July in 2006 and in 2007. The number of pollen grains produced per flowering head was also counted for grass species observed at study sites in 2007. According to the results of a vegetation species count for one square meter 10 grass species, with a total of 819 flowering heads, were recorded in 2007. The 10 species were dominated by 47% of sweet vernalgrass, 19% of tall fescue, 13% each of orchardgrass and Kentucky bluegrass. Notably, these four species represented 92% of the total flowering heads. Number of florets, number of anthers, and number of pollen per anther were counted for all ten species. The numbers of pollen per flowering head calculated using these data were 17.28×10^6 for orchardgrass, 9.10×10^6 for tall fescue, 1.61×10^6 for Kentucky bluegrass 1.28×10^6 for sweet vernalgrass. From these data, the number of pollen produced per square meter from 1st April to 10th July was estimated as 4304×10^6; being composed of 44% of orchardgrass, 34% of tall fescue, 11% of sweet vernalgrass and 4% of Kentucky bluegrass, and 7% other species.
