Tree nutrient
imbalances stimulated by iron (Fe) deficiency in calcareous soils often affect
citrus trees grown in the Mediterranean basin. Rootstock choice can help with
nutritional imbalances along with abiotic management issues. The present study evaluated
the growth and photosynthetic performances of young ‘Interdonato’ trees grafted
on ‘Alemow’, ‘Bitters’, ‘Carpenter’, Carrizo’, ‘Furr’, ‘sour orange’, ‘US812’,
‘Volkameriana’ and ‘X639’ grown in calcareous soils in Mediterranean region of
Turkey. Plant growth of the scion budded on Alemow, sour orange and
Volkameriana was significantly higher than those grafted on other rootstocks.
Bitters produced significantly smaller trees than Alemow, sour orange and
Volkameriana. In addition, scion grafted on sour orange (0.99) had the highest compatibility
Rootstocks affected leaf chlorophyll
concentration and PSII efficiency. Leaves of ‘Interdonato’ budded on
Carrizo citrange displayed a significant decrease in photosynthetic rate (PN), stomatal conductance and
PSII efficiency when compared to other rootstocks evaluated in this study.
Young Interdonato trees budded on to Bitters rootstock had significantly higher
PN in comparison to
Carpenter, Furr and Carrizo citrange in calcareous soil.
