    利用CIRAS-2型便携式光合测定系统,研究不同钾素营养水平下小南瓜的光合特性。结果表明:小南瓜叶片的蒸腾速率、气孔导度、净光合速率的日变化与钾素营养之间呈显著的正相关(r值分别为0.965 1、0.816 0、0.926 9),细胞间隙中C0_2浓度日变化与钾素营养之间呈显著的负相关(r=0.847 9)。The photosynthetic characteristics of small Cushaw at different potassium levels was measured by portable photosynthesis systems CIRAS-2. The results showed that transpiration rate, stomatal conductance and net photosynthetic rate in leaves of small Cushaw were significantly and positively correlated with potassium level (r=0.9651, r=0.8160, r=0.9269), but intracellular concentration of CO_2 in leaves of small Cushaw were significantly and negatively correlated with potassium level (r=-0.8479)
