要旨:
In ordert to input ecosystem model, photosynthetic traits were measured for three phenological stages. 生態系モデルのインプットデータとして、個葉の光合成特性のデータを、3つのフェノロジーの段階に測定を行った。
Photosynthtic rate at light satulation point (1500 PPFD) was measured by using LI-6400. Red-blue light of LI-6400 was used as the light source. CO2 concentration of the reference gas was kept as 370 ppm.
使用機器:
LI-6400, Li-cor, USA
手順 2:
説明:
Measurement for light-photosynthetic curve
The light intensity was decreased and photosynthetic rate at each light intensity was measured. At dark condition, the dark respiration was measured.
手順 3:
説明:
Calculation
Amax, Vcmax, initial slope of the light curve, and dark respiration rate were calculated.
