Desiccation tolerance changes in winter rape leaves grown under different environmental conditions
- 1 Institute of Botany, University of Warsaw, Warszawa, Poland
The results of studies performed on winter rape leaves (Brassica napus L. var.oleifera L., cv. Górczański) indicated that independently of the plant cultivation conditions and of the leaf growth rate, all leaves showed significant increase in desiccation tolerance at the beginning of leaf expansion. The increase in tolerance was correlated with the formation of a central vacuole in the mesophyll cells. Therefore, the high desiccation tolerance of vacuolised cells in comparison to the non-vacuolised ones is supposed to be due to the higher ability of the former to avoid cytoplasm dehydration. Development of frost tolerance in the leaves during autumn does not seem to be causally related to desiccation tolerance changes.
