| 摘 要： | 对大田栽培的347×2129、转1645×1987、27×2129、转4号×1987、转1号×2129、转2号×2129六个蓖麻材料光合特性进行了研究．结果表明：几种供试材料都不存在光合午休现象．蓖麻叶片净光合速率Pn与有效辐射强度PAR的日变化均呈单峰曲线．气孔导度从早上8：00就开始下降．材料347×2129、27×2129的净光合速率Pn显著高于其他6个品种．

| Abstract: | The photosynthesis characters of 6 castors were studied in contrast with Tongbi No. 5. The indexes including photosynthesis rate （ Pn ）, stomatal conductance（Cond）, photosynthetic active radiatio and intercellular CO2 concentration （Ci） were measured by L I- 6400 portable photosynthesis system in the open air. The result showed that the mid-day depression of photosynthesis is not existed in all the tested materials, and the changes during the day in net photosynthetic rate （Pn） and photosynthetic active radiatio（PAR）of 6 mature tree peony leaves was typical single peak curve, The change trend between Pn and PAR with stomatal conductance are very different. The stomatal conductance begin to decrease at 8 ： 00am. 347 × 2129 and 27 × 2129 are used as breeding material for future. |
