CONTROL OF IRON CHLOROSIS AND REPLANT DISEASES IN PEACH BY USING THE G.F.677 ROOTSTOCK.
One other problem is the replant of old peach orchards.
For the solution of the problems a research work is carried out in the Pomology Institute of Naoussa to find resistant rootstocks.
In 1972 one experiment was established in a farm where was eradicated one of old peach orchard and the trees were showing very strong symptoms of iron chlorosis. In this experiment were compared two rootstocks: Local wild peach seedling and G.F.677 (hybrid peach X almond). On the two rootstocks was grafted the peach variety Vivian. The results till 1982 are the following:
- Iron chlorosis was lower on G.F.677 rootstock about 40%
- The growth and yield of the trees on G.F.677 rootstock was much higher than on peach seedling.
