MATERIALS AND METHODS For most of the work volunteer orchard grass (Dactylis glomerata) plants were used. In determining the period of blooming 25 heads were observed at one-hour intervals both night and day. Intervals of this length proved satisfactory, since a number of assistants were used for making the counts at the end of each hour, over a short period of time. Data are reported on only 22 heads as 3 of the heads were discarded during the experiment.
