Abstract
In recent years, an attention to the gene flow problem of dispersal of artificially modified genes to the natural environment by airborne pollen is increasing rapidly. Especially for wind-pollinated crop, there is a possibility that pollen diffuses quite widely depending on meteorological conditions. In order to deal with such problems, it is necessary to develop the model that can estimate the pollen dispersal and the hybridization mating appropriately. In this paper, I present an aerobiological mechanistic model for assessing pollen dispersal and hybridization using hourly data. This model considers hourly change of the meteorological conditions and daily change of biological conditions. And it was constructed for estimating the spatial distribution of hybridization percentage in a recipient field. The effectiveness of the model was certified by the field experiments. The model was constructed in consideration of physical processes and biological processes. The algorithms presented here can be applied to estimate the total pollen deposition and hybridization mating for many kinds of plants.
