Abstract:
An experiment was conducted on private orchard at Abbasiya / Najaf governorate for season
2017 to investigate the effects of spraying trees local apple fruit cv. Kufie with Algae extract
2% and 3%, Daminozid at conc. Of 250 mg/L and Zinc sulphate at conc. Of 3000 mg/L after 40
days from full bloom stage in single way or combination. Fruits were picked after 85 days from
full bloom. The experiment included 12 treatments with three replicates . It is adopted according
to Randomized Complete Block Design (RCBD) , and the results were statistically analyzed
according to Duncan test at the probability level of 5%. The result indicated that the diameter of
fruit , length of fruit , weight of fruit, volume of fruit , moisture of pulp , moisture of peels ,
fruit firmness percentage of weight of juice , percentage of titrable acidity , percentage of total
soluble solids , percentage of T.S.S / TA , vitamin C , and percentage of calcium pictate,
increasing significantly with increase concentration of Algae extract that interaction with
Daminozid and Zinc Sulphate and reducing percentage of cracking compared with control
treatment. The treatment of (Algae extract 3% + Daminozid 250 mg/L + ZnSO4 3000 mg/L )
gave the highest rate of parameters studied. |
