EFFECTS OF SOME ROOTSTOCKS ON MINERAL NUTRIENT UPTAKE IN TWO PISTACHIO CULTIVARS (PISTACIA VERA L.)

Rootstock selection plays one of the most important roles in orchard management.
In Kerman province and in other pistachio growing areas of Iran, pistachio cultivars are grown on pistachio seedling rootstocks of different cultivars such as ‘Badami Zarand’ and ‘Ghazvini’. This experiment was carried out in pistachio research station (Fiez-abad area) in Khorasan province (Northeast Iran) in two years (2006-2007) with three replications and on five-year-old pistachio trees.
Six cultivars (P. vera L.) were used as rootstock including: Badami-sefid, Sarakhsi, Kalle-ghouchi, Daneshmandi, Barg-Seyah and Akbari and two cultivars of Akbari and Barg-seyah were used as scion.
Leaf analysis showed that there were significant differences (p<0.01) in the amount of potassium, phosphorus and iron content among treatments.
Interaction between Akbari scion budded on Badami Rootstock was the most effective on the amount potassium and zinc acquisition (1.56% and 11.05 ppm respectively). The least amount of potassium and zinc was obtained from the interaction between Akbari scion budded on Daneshmandi rootstock (0.80% and 7.33 ppm respectively). Barg-seyah scion budded on Kalle-ghouchi rootstock resulted in the most amount of iron (241 ppm) and copper (12.15 ppm).
