Summary

The air over a crop of flowering winter oil-seed rape was sampled for 39 days with an automatic volumetric spore trap. Considerable quantities of rape pollen were caught on most days. Density of pollen showed marked diel periodicity; few grains were caught at night and at mid-day, peaks occurred in late morning and early afternoon. It is concluded that wind plays a considerable role in pollination of the crop.
