Abstract
This work was executed during the two growing seasons of 2004 & 2005 on eight olive "Olea europaea L." cultivars: Manzanillo, Coratina, Koroneiki, Chemlali, Wardan, Picual, Dolce, and Arbiquine. Trees were grown at Ali Mubarak farm in South Tahrir region Research Station. The objectives of this study to evaluate these cultivars were among 46 cultivars collection in this region. These trees were planted in sandy soil besides, it received the annual fertilizers program and irrigated with Nile water using drip irrigation system. Concerning the tree characteristics, Chemlali and Koroneiki cvs. surpassed other cultivars in plant height and trunk circumference. On the other hand, Dolce and Wardan cvs. were the least in plant height and canopy of the tree. Meantime, Coratina cv. trees achieved the highest values of canopy circumference, shoot length and shoot diameter. The reverse was true for Wardan and Picual cvs.. Whereas, Coratina and Picual cvs. exhibited the highest assimilation area. Arbiquine cv. gave the highest number of internodes and number of leaves/shoot and Wardan cv. gave the highest least leaf area . However, Hanzanillo cv. exhibited the least leaf area and both Manzanillio and Wardan cvs. gave the least number of internodes. As relating to full blooming, Chemlali cv. Was the earlier, but Koroneiki cv. was the latest one. Chemlali and Koroneiki cvs. has the highest significant number of inflorescence/shoot and sex expression percentage. Dolce cv. exhibited the longest fruit and seed besides, wardan and picual cvs. showed the highest fruit diameter. As for seed diameter, Manzanillo cv. surpassed other cultviars. in this character. Reversly, Arbiquine cv. seed was the shortest in length and Chemlali cv. was the least in width. Manzanillo cv. was the highest fruit weight while, Wrdan cv. was the highest flesh/seed ratio. The same cultivar and Picual cv. showed the highest flesh weight in 2004&205, respectively. Arbiquini and Chemlali cvs. gave the highest fruit set percentage, while Manzanillo cv. exhibited the least one. The highest oil percentage were in picual and Aarbiquine cvs., however Chemlali cv. was the least in oil percentage. Dolce and Picual cvs. surpassed other cultivars in yield. On the contrary, Chemlali and Aarbiquine cvs. were the least in yield. Eventualy, we can recommend planting Dolce, Picual and Aribquine cvs. under The Region of South Tahreer for table, double purpose and oil consumption, respectively. In addition, studying on the rest of the cultivars low in production has to be carried.
