摘　　要： 利用灵敏度高，专一性强的放射免疫法（ＲＩＡ）测定了苦瓜和瓜萎不同器官中皮质醇的含量。结果表明：苦瓜和瓜萎各器官均含有皮质醇，且含量在５０～４５０ｎｇ／ｇ．ＦＷ；顶芽中含量最高，其次是花器官；苦瓜和瓜篓雌花皮质醇含量明显高于雄花，且雌花在授粉后当天含量最高，说明皮质醇可能在植物的生长发育过程中起某种作用。 Useing extremly sensitive and specific RIA method,cortisol was found in every organs from M.charantia L. and T. kirilowii Maxim. The level of cortisol was from 50-450 ng / g. FW, buds contained the largest amount of cortisol, and followed by flower organs. The contents of cortisol in female flowers were higher than that in male flowers. Cortisol in fernals reproductive organs of M. charantia L. and T. kirilowii Maxim.reached the highest level after pollination just the day. this indicates that cortisol may play some roles in growthand deVelopment of plants.
