The study was conducted at the Horticulture Department, Faculty of
Agriculture, University of Damascus, during the season of 2002 and 2003, in
order to study the effect of dipping apple fruits for the tow apple sorts for 5
minutes with some chemic
al substances, α-Tocopherol (0.25%) and
Prohexadion-Calcium (1%).
The fruits were stored at AlMaze cold storage unit under the normal
storage condition (0-1ºC, 93% R.H.), to find out some effects of these
treatments on some physical, chemical, and physiological changes of treated
and untreated apple fruits, especially: fruit weight, firmness, starch, and
soluble solids content.
Analysis of variance indicated a significant difference in storage ability of
both fruit apple samples in case of dipped fruits in Procalcium solution 1%
compared with control fruits. The tocopherol treated fruits were sometimes
significant.
The results showed a reduction in fruit weight in case of treated sample
during cold storage time. Fruit firmness was significantly better in both
treatments of procalcium 1% and tocopherol 0.25%compared with control,
and reducing physiological disorders during cold storage period.
