中文摘要	用Li-6400型便携式光合作用测定系统和配套的荧光叶室,对4个不同生态型扁蓿豆的光合特性和光适应能力进行了比较研究.结果表明:内蒙古土默特左旗的生态型00-61扁蓿豆和黑龙江松嫩草原的生态型93-21扁蓿豆最大净光合速率(P_(max))、实际光化学效率(Ф_(PSⅡ))、光化学荧光猝灭系数(q_P)、暗呼吸速率(R_d)均较高,而非光化学荧光猝灭系数(q_N)较低,表明二者具有相对高产的生理和生物物理基础.00-61扁蓿豆还具有较高的光饱和点,对强光有更大的光合适应性,适合种植在相对高光环境.内蒙古正蓝旗浑善达克沙地的生态型90-36扁蓿豆,q_P较低而q_N较高,具有相对较强的防御光抑制破坏的能力.内蒙古锡林郭勒盟锡林浩特典型草原区的生态型00-81扁蓿豆,光补偿点和光饱和点均较低,耐荫力较强,与其他生态型相比更能适应相对弱光环境.
英文摘要	A comparative study was made on the photosynthetic characteristics and photo-adaptability of four Melilotoides ruthenica ecotypes by using Li-6400 portable photosynthesis system and attached chlorophyll fluorescence chamber. Among the test ecotypes, ecotype 00-61 from Tume-tezuoqi of Inner Mongolia and ecotype 93-21 from Songneng grassland of Heilongjiang had higher maximum net photosynthetic rate (P_(max)) , photochemical efficiency (Phi_(PSⅡ)) , photochemical quenching coefficient (q_P) and dark respiration rate but lower non-photochemical quenching coefficient (q_N) , indicating their higher potential to produce more biomass. Ecotype 00-61 also had higher light saturation point, and thus, had higher photo-adaptability to strong light, being adaptable to plant in relatively high-light environment. Ecotype 90-36 from Hunshandake desert area in Zhenglanqi of Inner Mongolia belongs to Melilotoides ruthenica var. oblongifolia, which had lower q_P and higher q_N, and thus, had higher defensive capability to light-inhibition damage than other three ecotypes. Ecotype 00-81 from the typical grassland of Xilinghot in Xilinguole League of Inner Mongolia had lower light compensation point and light saturation point, exhibiting stronger shade tolerance and higher adaptability to weak light, comparing with the other three ecotypes.
