تأثير المعاملة بمادة 1- ميثيل سيكلو بروبان (MCP)‎ و التعبئة في أكياس بولي إيثيلين في زيادة القدرة التخزينية لثمار الدراق من صنف البرتا

الملخص EN

Fruits of the peach (Prunus persica) cv.

Elberta, harvested at Surghia, were post-harvested, treated with three concentrations of 1-MCP [ 1-Methylcyclopropene] for 20 hours at 21°C and then packed in plastic boxes or polyethylene packs at a thickness of 3 microns.

After that, they were stored at 1 °C for 42 days.

The treatment of 1-MCP showed a significant effect on saving the firmness of the fruits and decreased the rate of reduction of juice's Titratable Acidity (TA).

Besides, it saved the Total Soluble Solids (TSS) and vitamin C content at high levels after 42 days of storage.

The results showed high significant superiority using polyethylene packs, as this reduced the rate of weight loss to about 6 times less than the control; while results didn't show any positive effect on the different quality parameters when polyethylene packs were used with 1-MCP.
