| Inhoud: |
Tomato plants, varieties FER and Earlygirl (both iron efficient), were grown under low Fe conditions for 9 days. Rhodotorulate -14C was isolated from Rhodotoruiate pilmanae cultured with 14C-sucrose. The 14C- Rhodotorulate -Fe and Rhodotorulate- 59Fe were added to the Fe-stressed plants for 6, 24 and 48 hour periods. It was evident from autoradiograms and tissue sampling that 59Fe and 14C were abundant in roots, stems and leaves. The 14C autoradiograms showed especially high density in the small younger leaves, as was found also with 59Fe. Unlike synthetic chelates rhodotorulate (or metabolized derivatives) were readily absorbed by the roots and translocated to the leaves. |
