EFFECT OF CALCAREOUS SOIL ON VEGETATIVE GROWTH OF OWNROOTED AND GRAFTED KIWI FRUIT TREES

These trials tested the resistance to different soil active lime concentrations of kiwi fruit trees of the cultivar "Hayward" and of the rootstock "D1", grown in containers.

Observations on plant growth, symptoms of chlorosis, leaf clorophyll content and the leaf content of some mineral elements showed that in general the "D1" rootstock has a greater resistance to lime than the ownrooted "Haywards". These preliminary results suggest that with this rootstock the species can be grown even in soils having an active lime concentration of around 8%.

The trials described were performed in a controlled environment, and the results clearly need to be verified on fully productive plants in the orchard.
