| Outline of Final Research Achievements |
Relationship between shoot growth and water utilization and the contribution of it’s control by water channel in soybean plants were examined. Soybean shoot grown in wet soil condition was large in summer (high temperature), however vigorous shoot growth was not found in autumn regardless of soil water condition. Soil temperature treatment including high and low soil temperature in summer and autumn showed the difference in shoot growth between the seasons only, not soil temperature treatment. But the difference in shoot growth between not only the seasons but also soil water treatment were found in soybean plants grown in hydroponic culture. These suggested that soybean shoot growth would be controlled by water channel in leaf and this mechanism changed in response to cultivation.
