摘要：
Label was incorporated by placing potted stems of Asclepias curassavica into a chamber into which 14CO2 was introduced. Based on scintillation counts, detectable levels of label were found in pollinia of all flowers that opened 1-19 days after incorporation; highest levels occurred from days 9-13 post-incorporation. Nectar was also found to have label. -from Authors
