| Abstract | ||
| Chemical constituents of six table olive cvs. was carried out through two successive seasons 2002 and 2003. In (2002), N content in leaves of bearing shoots of Eggizi balady cv. was significantly higher (1.626%) than in other cvs., while it was the lowest (0.699%) in Kalamata cv. At first of July, N content was the highest (1.251%) in bearing shoots than in other dates, while in non bearing shoots N content of Mission leaves was the highest (1.519%) compared to other cvs., while it was the lowest in Dulci cv. as it averaged (0.675%). In (2002), P content of Eggizi Shami was the highest (0.52%), while it was the lowest in Mission cv. with average (0.107%) in comparison with other cvs. At first of July, P content in bearing shoots was higher (0.755%) than in other dates, while it was the lowest (0.071%) at first of May. C/N ratio in bearing shoots of Kalamata cv. was the highest (6.659), while it was the lowest (1.837) in Eggizi balady. C/N ratio in non bearing shoots of Eggizi balady was significantly higher (6.074) than in other cvs., while it was the lowest (2.069) in Kalamata. At 1/10, C/N ratio was significantly higher (5.320) in non bearing shoots than in other dates, while it was the lowest (3.441) at 1/6. Carbohydrate content was significantly higher (5.152%) in Kalamata cv. compared to other cvs., while it was significantly lower in Eggizi Koprosi than in other cvs. with average (2.43%). At 1/6 carbohydrate content was significantly higher (5.369%) than in other dates, while it was lower (2.932 and 3.064%) at 1/10 and 1/ In non bearing shoots, carbohydrate content in Eggizi balady was significantly higher compared to other cvs. with average (5.112%), while it was the lowest (2.532%) in Dulci compared to other cvs. At 1/10 carbohydrate content was the highest (5.686%) than in other dates, while it was the lowest at 1/5 with average (2.763%). Ca content in bearing shoots of Eggizi Shami was the highest (0.949%) than in bearing shoots of other cvs., while it was the lowest (0.681%) in Dulci . At 1/5 Ca content was the highest in bearing shoots (1.221%) compared to other dates, while it was the lowest (0.552%) at 1/10. Ca content in non bearing shoots was significantly higher (1.008%) in Eggizi Koprosi than in other cvs. while it was the lowest (0.605%) in Eggizi Shami than in other cvs. At 1/10 Ca content was higher (1.073%) in non bearing shoots than in other dates, while it was lower (0.297%) at 1/5 compared to other dates. K content was the highest (0.868%) in bearing shoots of Kalamata while it was the lowest (0.581%) in shoots of Eggizi Shami than in other cvs. At 1/5 K content was the highest (0.819%), while it was the lowest (0.641%) at 1/10 compared to other dates. K content in non bearing shoots was the highest (0.978) in Eggizi Koprosi, while it was lower (0.68%) in Eggizi Shami than in other cvs. At 1/10 K content was significantly higher (0.856%) in non bearing shoots than in other dates, while it was lower at 1/5 (0.723%) than in other dates. From these results, it could be concluded that there were varietal difference between cultivars in N, P, K, Ca and carbohydrate contents in leaves of on and non bearing shoots. Similar varietal differences was observed in C/N ratio in leaves in on and non bearing shoots. | ||
