| Outline of Final Research Achievements |
The relationship between depth of florets in foliage, meteorological factors, pollination and seed setting were examined with a model experiment in which flowering rice grown in the 4L pots were set in canopy at different heights. There was an optimum height of florets in the view seed set percentages. Under low wind condition below 0.5 meter per second made the pollination unstable. Variation of pollination under the different depths was well explained by wind velocity around the florets, but did not completely correspond to seed sets.
