'Tami'-A New Israeli Mandarin: Effect of Three Rootstocks on Yield, Fruits Size and Fruits Quality

摘要

'Tami' ('Temple' tangor×'Michal' mandarin), a new Israeli patent, early-mid season, very low seeded mandarin, grafted on rootstocks C-35 (Citrus sinensis×Poncirus trifoliata) , 812 (C. reticulata×P.trifoliata) , and 'Sour Orange' (C.aurantium L.), was planted at 5m×3m (667 trees/ha) on August 2001. The growth of tree without thorns was slowly and trees were small. The cumulative four years yield from the above ' Tami'/rootstocks combinations was: 112, 102 and 97 ton/ha. Average fruits weight was high: 189, 159 and 179 g/fruit. Average T. S. S level was reasonable; 11.4% , 11. 5% and 11.7%. Average total acids level was low: 0. 6% , 0. 6% and 0. 58%. Average Juice content was high; 56. 9% , 59. 7% and 55. 8% , respectively for C-35, 812 and Sour Orange. Picking date every year was at middle of November. The trees did not show any symptoms of incompatibility between scion and rootstock. Leaves and fruits did not show any sensitivity to ' Alternaria Brown Spot' fungi. Based on the above results and observation, the new Israeli mandarin, 'Tami' , seems to us as a promising variety for early-mid season, under the Israeli coastal climatic conditions.
