RESEARCH ON THE EFFECT OF GRAPE GUARD DURING THE COLD STORAGE OF THOMPSON SEEDLESS CV.

This research was carried out at the laboratory of Postharvest physiology and cold rooms of the Department of Horticulture, Faculty of Agriculture, University of Ankara.

The aim of the research was to determine the effects of slow release SO₂ generators on the storability of Thompson Seedless cv. grown in Turkey.

Thompson Seedless were harvested from Manisa region.
They were packed with quick-release SO₂ generators and transported to Ankara.
Then the quick-release SO₂ generators were taken out and grapes were pre-cooled.
After that, slow release SO₂ generators were placed with them and the grapes were stored at 0 °C and 90 – 95 % R.H. conditions.

The experiment was conducted in Randomized Plot Design and parameters like the appearance, flavour, stem and berry color, total soluble solid content, titratable acidity, SO₂ residue, decay rate, and weight losses were measured at 15 days intervals at in order to determine the effect of slow-release SO₂ generators on storability of Thompson Seedless cv.

As a result of this research, Thompson seedless could be well-stored for 105 days with a slow-release SO₂ generator + perforated PE/6.8 and 10 kg and slow-release SO₂ generator + unperforated PE/6.8 and 10 kg treatments.
