Abstract
This study was conducted in Al-Lateffea experimental station , Horticulture and Forests General Company for the growing season of 2004 , in order to reduce the percentage fruit dropping and improving the yield content in the date palm Braim cultivar. Thirty six trees were selected with 25 years old planted 10x10 meter. The bunches were sprayed with GA3 at a concentration of 10 , 20 mg/l and sorrel extract at 5, 10 , 15g/l and bagged the bunches with netted plastic bags . The experiment included 12 treatments arranged at RCBD with three replicates for each treatment and the experimental results showed that the percentage of a fruit drops decreased in the three stages of Khalal , Rutub and Tamur by a percentages of 44.11 , 68.81 , 61.67 % , respectively when bunches sprayed with GA3 at 20 mg/l and bagged , while the treatment with sorrel extract at 15 mg/l and kept in netted bags reduced this percentage by 51.78 % , 34.81 % and 32.90 %. Fruits weight and size increased by a percentage of 34.58 % , 35.44 % when GA3 at 20 mg/l are used and bunches kept in netted bags while the increment was 21.55% , 24.47% when sorrel extract at 15 g/l was used and bunches kept in netted bags. Bunches weight were increased by a percentage of 87.39 % when GA3 at 20 mg/l where used and bunches kept in netted bags. In the same time all the treatments causes a reduction in dry matter , TSS and sugars as compared with the control treatment.
