초록

This study was conducted to investigate the net photosynthetic rate, stomatal transpiration, stomatal conductance, water use efficience, and intercellular $CO_2$ concentration in Allium ochotense leaves and Allium microdictyon leaves. The light compensation point was 4.2 ${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ in Allium ochotense leaves and 5.2 ${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ in Allium microdictyon leaves. The lght saturation point was approximately 800 ${\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$ in between Allium ochotense leaves and Allium microdictyon leaves. The phtosynthetic rate of Allium ochotense leaves was higer than that of Allium microdictyon leaves. On the other hand, at more than $30^{\circ}C$, it appeared that the values of net photosynthetic rates of Allium microdictyon leaves were higher than that of Allium ochotense leaves. These results suggest that growth of those Allium ochotense plants are appropriate for relatively cool temperature site compared to Allium microdictyon plants.
