| Abstract | ||
| Performance of six table olive cvs. was investigated during two seasons (2002 and 2003) under desert conditions. Average leaf area in (2002) at non bearing shoots was significantly higher (7.183 cm)2 than leaf area at bearing shoots (6.84 cm2). Leaf area differed according to olive cvs. In Dulci cv., it was the highest (9.347 cm2), while it was the lowest (4.70 cm3) in Mission cv. compared to other cvs. Increasing rate of Dulci shoot growth was significantly higher (1.616 cm), while it was lower (0.894 cm) in Eggizi Shami compared to other cvs. Increasing rate of growth from 1/5 to 1/6 was higher (2.973 cm). While, it was lower at the period from (1/9-1/11) with average (0.00 cm). GDD at FB in the first season (2002), was significantly higher (105.0) in Mission cv. than in other cvs. while, it was lower (70.22) in Eggizi balady. Julian dates of bud break, beginning of flowering, FB and end of flowering was significantly higher in Kalamata than in other cvs. with average (74, 93.67, 104.70 and 114.0, respectively). While it was considerably lower in Eggizi balady than in other cvs. with average (61.33, 68.67, 81.33 and 87.33, respectively) for bud break, beginning of flowering, FB and end of flowering. In 2002, flowering density was significantly higher (37.63, 37 and 35) for Kalamata, Eggizi balady and Dulci cvs. While, it was significantly lower in Eggizi Koprosi, Mission and Eggizi Shami cvs. with average (28.67, 30.33 and 31.67, respectively). Average number of perfect flowers / inflorescence was higher in Kalamata (17.00) and Eggizi balady (16.00) than in other cvs. while, it was lower in Eggizi Shami (9.667), Eggizi Koprosi (10), Dulci (10.33) and Mission (11.67) compared to other cvs. Average percentage of pollen germination of Dulci cv. was the highest (69%), while it was the lowest (53%) in Mission. Initial fruit set of Dulci cv. was the highest (101.70 fruit / m) while, it was the lowest (53.94) in Mission. Final fruit set of Dulci was higher (59.38), while it was the lowest in Mission cv. (29.03). In (2002) increasing rate of fruit length and diameter was significantly higher at harvest (3.25 and 2.25 cm) than in other times. While it was lower in the first beriod of determination. Increasing rate in fruit length in Eggizi Shami was the highest (2.78 cm), while it was the lowest in Mission (2.14 cm). Increasing rate in 2002 in fruit diameter in Eggizi Shami was the highest (2.06 cm), while it was the lowest (1.29 cm) in Kalamata . In (2002), fruit weight of Eggizi Shami was the highest (13.03 gm), while the lowest was observed in Eggizi Koprosi with average (4.80 gm). Similar trend was observed in fruit length, diameter, size, flesh weight, seed weight and seed thickness. Oil content of Kalamata cv. was the highest (38.11%), while it was the lowest in Eggizi Koprosi with average (31.85%). Peroxide value of Eggizi Koprosi oil was the highest (19.18), while it was the lowest in Mission and Eggizi Shami oil with average (12.4 and 2.56). Acid of Eggizi balady oil was higher (2.00) compared to other cvs., while it was the lowest in Mission oil with average (1.533). Total phenols of Eggizi balady oil was significantly higher (141.50) compared to those in other cvs., while it was the lowest in Mission and Eggizi Shami oil with average (103.9 and 104.40). | ||
