Abstract

Tops and roots of Medicago 8ativa plants raised in culture solution to which 75Se�labelled selenite or selenate had been added were shown to release 0�5-3�0% of their total selenium in volatile form when dried at 70�C for 48 hr. The volatile selenium compounds were collected on activated charcoal.
