Abstract

In a pot experiment the following grapevines were grown in a calcareous soil: Pinot blanc own-rooted and self-grafted, grafted on SO 4 and on 3309 C; SO 4 own-rooted, self-grafted and grafted on Pinot blanc; 3309 C own-rooted, self-grafted and grafted on Pinot blanc. The occurrence of chlorosis was strongly affected by graft combinations. In self-grafted 3309 C plants the specific conductivity was significantly reduced as compared to own-rooted ones. Own-rooted SO 4 plants showed the highest specific conductivity, associated with the highest rate of shoot growth and leaf chlorophyll content.
