| Abstract | ||
| Astudy was conducted on local in private orched in Dourah, Baghdad governorate on orange trees var. Mahli grafted on sour orange through 2010 – 2011 seasons to study the gibberellins spraying on yield and chemical, physical properties. The experiment in duded eight treatment that control ,GA3 100mg .L-1 at February begging. Spraying in with GA3 100 mg.L-1 mid February and then spray two times at the same dates with five replicates four each treatment , and the number of trees would be 40 trees. The design used RCBD. The results showed that the treatment at the beginning of February with mid February. had superiority which gave maximum rate in weight, volume, fruit diameter, lobs number, juice weight, juice volume, total soluble solid and total yield so it gave yield reached 40.08 , 43.70 kg. tree-1), while the control gave less yield reached 20 , 23 kg. tree-1 . The effect of the date of fruits sampling to investigate the effect of spraying on the upper proportion ,the sampling of 5/12 gave high rate for upper properties, while the dates 10/10 gave less properties. Acidity fruit juice for the control treatment gave maximum measure reached (0.59 – 0.62 mg. 100 ml) for the two seasons. The GA3 treatment at beginning February and mid February and march begging minimum acidity reached (0.53 – 0.57 mg. 100 ml-1 succefully two years. Vitamin C content the treatment of GA3 at beginning February and March beginning gave maximum content reached (55.36 – 63.40 mg. 100g-1), while the control gave less content reached (52.31 – 59.20 mg. 100g-1) for season study succefully. | ||
