Ion absorption through the aerial root of Epidendrum


, : Ion absorption through the aerial root of Epidendrum. Protoplasma 60(1): 1-6

Uptake of S35O4 by aerial roots of Epidendrum was investigated by microautoradiog-raphy. During a 30-minute application to the velamen the isotope was transported through the cortex and the passage cells of the endodermis and pericycle and accumulated in the protoxylem vessels.
