    The effects of "Tuzcu" sour orange clones selected from the eastern mediterranean region on the fruit yield and quality of kütdiken lemon
    (1996) Hakan Demirkeser, T.; Tuzcu, Önder
    This study has been carried out at the Department of Horticulture, the Faculty of Agriculture, the University of Cukurova. Adana, Turkey. In this study the effects of TUZCU sour orange clones, with 29 various genetic make up (TUZCU 33-1. TUZCU 33-2. TUZCU 33-3, TUZCU 33-4, TUZCU 33-5, TUZCU 33-6, TUZCU 33-7, TUZCU 33-7, TUZCU 33-8, TUZCU 33-9, TUZCU 33-10, TUZCU 33-12, TUZCU 01-13, TUZCU 01-14, TUZCU 01-15, TUZCU 01-16, TUZCU 01-17, TUZCU 01-18, TUZCU 01-19, TUZCU 01-20, TUZCU 01-21, TUZCU 01-22, TUZCU 01-23, TUZCU 01-24, TUZCU 31-25, TUZCU 31-26, TUZCU 31-27, TUZCU 31-29, TUZCU 31-30, TUZCU 31-31), selected from the Eastern Mediterranean region, on the fruid yield and quality of "Kütdiken" lemons have been studies throughout two years. Clones have shown rather different effect on fruit yield and quality. TUZCU 01-14, TUZCU 01-16 and TUZCU 01-24 clones gave high fruit yield and had also a positive effect of fruit quality. While TUZCU 33-4 clone is the clone which has the most negative effects on fruit yield. The increasing positive effect of fruit quality of TUZCU 31-30 clone, despite TUZCU 33-10 clone's high yield characteristic but it influenced negatively fruit quality.

    Performance of "rio red" grapefruit on seven rootstocks in the Eastern Mediterranean Region of Turkey
    (Tarbiat Modares University, 2014) Yildiz, E.; Kaplankiran, M.; Hakan Demirkeser, T.; Toplu, C.; Uysal-Kamiloglu, M.
    The effects of rootstocks such as 'sour orange' (Citrus aurantium L. var. 'Yerli'), 'Carrizo' and 'Troyer citranges' (Citrus sinensis Osb. x Poncirus trifoliata Raf), 'Smooth Flat Seville sour orange' (Citrus spp. hybrid of uncertain origin), 'Brazilian sour orange' (Citrus aurantiam L. var. 'Brasilian'), 'Volkameriana' (Citrus volkameriana Tan. and Pasq.) and 'Calamondin' (possibly Citrus reticulate var. austere×Fortunella hybrid, Swingle) on plant growth, fruit yield, and quality of 'Rio Red' grapefruit were investigated from 2008 to 2012. Rootstocks were found to have significant effects on plant growth, fruit yield, and quality. 'Rio Red' grapefruit trees budded on 'Carrizo' and 'Troyer citranges' showed higher vegetative growth parameters (canopy height, diameter, and volume) than the trees on the other rootstocks. The trees on 'Volkameriana' and 'Carrizo citrange' produced higher percentage of cumulative yield of about 55.1 and 34.3%, respectively, than the trees on 'sour orange'. 'Rio Red' grapefruit budded on 'Carrizo citrange' had higher fruit quality such as thin rind, high juice content, and more color development than the other rootstocks. 'Carrizo citrange' was the most promising rootstock for 'Rio Red' grapefruit in Dörtyol, Eastern Mediterranean region of Turkey.
