The new cultivations of table grape are conducted in protected conditions under plastic fi lms, which enable early or delayed harvesting. The aim of this work was to evaluate the effects of three coloured plastic fi lms (white, yellow and red) on vegetative and productive behaviour of two cultivars of table grapes, Italia and Red Globe. The study was carried out in Turi (BA) on vineyards in full production. The parameters evaluated were: PPFD and temperature under the fi lms, index of Huglin, length of shoot, number of leaves/shoot, leaf area yield per vine, cluster and berry weight, soluble solids content, pH, titratable acidity, polyphenols, anthocyanins, ascorbic acid content and total antioxidant activity. The lower transparency to sunlight of yellow and red plastic fi lms caused a slight reduction of light intensity. In both cultivars the reduction of light intensity did not signifi cantly affect vegetative growth and yield. The grapes grown under the yellow and red coloured fi lms had a much higher total antioxidant activity with respect to those grown under the white one (+86 and +91% respectively for cultivars Italia and Red Globe under yellow fi lm and +72 and +48% respectively for cvs Italia and Red Globe under red fi lm).
Table grapes of cv Italy and Red Globe were grown under colored plastic fi lms
Plastics fi lms have led to less transparency of light
The colored fi lms did not have negative effects on growth and yield of the two cultivars
The grapes grown under coloured fi lms had higher values of total antioxidant activity

Key words: table grapes, plastic fi lm, PAR, antioxidant activity
