Effects of modified atmosphere packaging on quality parameters of minimally processed table grape during cold storage
2015
‘Vittoria’ and ‘Red Globe’ table grapes were packed in microperforated polypropylene films (passive MAP) and non-perforated polyethylene (active MAP: 1) 20% CO2 + air; 2) 5% O2 + 15% CO2 + N) and stored at 5 °C for 28 days. Microperforated polypropylene packages had the highest postharvest performance in both cultivars until 14 days of cold storage, with reduced weight losses, rachis and berry decay. Total soluble solids content slightly increased in non-perforated polyethylene boxes as a consequence of the higher weight losses, particularly in active MAP with 5% O2 + 15% CO2 + N, while no significant differences were found for titratable acidity. Non-perforated polyethylene packages showed…
Interaction between Acremonium byssoides and Plasmopara viticola in Vitis vinifera
2008
The endophytic fungus Acremonium byssoides was isolated from the leaves of grapevine cv. Regina Bianca to determine whether it could act as an antagonistic endophyte of the downy mildew agent Plasmopara viticola. The occurrence of this fungus was ascertained in 34 grapevines (cultivars Regina Bianca, Catarratto and Insolia) representing all the grapevine plants in an experimental vineyard located in Sicily and which had never been treated with any fungicides. The isolation frequency of the endophytic Acremonium strains was assessed in several plant organs by means of monthly samplings over a 2-year period. The endophyte was found in all the grapevines, with higher frequencies in the cv. Reg…
