内容記述 |
To examine effects of soil drought stress on the production of potentially stress-related compounds in current-year seedlings of Fagus crenata, we collected seeds from two sites in the northern region of mainland in Japan. We then germinated and grew them in well-watered (watered once every two days) or water-stressed (no watering) conditions in an environmental chamber for ca. two weeks. The concentrations of biochemical compounds in roots were estimated to be in the range 0.31–0.76 μmol/gDW and 0.51–0.61 mg/gDW for free-proline and total flavonoids, respectively. Negative associations were found between the seedlings’ height at the start of the experiment and concentrations of free-proline but not total flavonoids in roots. After accounting for the effect of height, there was no significant difference between the two sites with respect to the concentrations of free-proline and total flavonoids in roots of seedlings. Regardless of biomolecules examined, the concentrations in roots of seedlings did not increase by the treatment of water-stress. Rather, in the seedlings from one site, it was found that the concentration of free-proline in roots was higher in the well-watered than in water-stressed conditions. These results suggest that there is a trade-off between the concentrations of free-proline in roots and the beech seedling size, whereas it is necessary to examine the relationship between the concentration of each flavonoid species and the seedling size. The water-stressed conditions in this study might have not been intense enough to drive the differences in the concentration of total flavonoids between seedlings from different experimental conditions. It was speculated that proline catabolism involves in the reduction of the concentration of free-proline in roots of the beech seedlings found in our water-stressed condition. |
