Performances of ‘Ok？tsu’ and ‘Clausell？na’ Satsuma Mandar？ns on D？fferent Rootstocks in Eastern Med？terranean of Turkey

The experiment was installed in D？rtyol, Turkey with the aim of evaluating the effects of the rootstocks of sour orange, Carrizo and Troyer citranges on plant growth, yield and fruit quality of 'Okitsu' and 'Clausellina' Satsuma mandarins (Citrus unshiu Marc.). 'Okitsu' Satsuma trees had the highest cumulative yield on Carrizo and Troyer citranges. Plants of this cultivar on sour orange had significant higher yield efficiency than trees on the other rootstocks. While 'Clausellina' Satsuma trees budded on Carrizo citrange had higher cumulative yield, yield efficiency of this cultivar had higher on Troyer citrange. The larger trees of 'Clausellina' Satsuma were those on Carrizo citrange, although canopy growth of 'Okitsu' Satsuma tress budded on Carrizo and Troyer citranges were similar. Fruit weight was highest in fruits of both 'Okitsu' and 'Clausellina' Satsuma cultivars budded on sour orange. The rind thickness and total soluble solids (TSS) of both cultivars were not affected by the rootstocks. The fruits of 'Okitsu' Satsuma trees on Carrizo citrange had higher juice content and high TSS:titratable acidity (TA) ratios were observed in fruits of 'Clausellina' Satsuma trees on Carrizo citrange. Instead of sour orange, Troyer citrange is suitable rootstocks for 'Clausellina' Satsuma, whereas both rootstocks evaluated are adequate for 'Okitsu' Satsuma
