RESUMO

Detached pistils of Lilium longiflorum were labeled with d-glucose-U-14C 24 hours after anthesis and then sampled for the next 6 days to determine the appearance of label into exudate from the stylar canal and the stigmatic surface of the pistil. Results were obtained with unpollinated cv. Ace pistils and pollinated cv. Ace pistils, selfed or crossed (cv. Croft pollen). Limited data were also obtained on cv. Croft pistils, selfed or crossed (cv. Ace pollen).
