Climatic influences on Mencía grapevine phenology and grape composition for Amandi (Ribeira Sacra, Spain)

Abstract

During the year 2009 we have studied the phenology and grape composition of Mencía cultivar in seven different situations (orientation and altitude) for Amandi subzone (D.O. Ribeira Sacra, Spain). The results showed the influence of terroir on the Mencía growth stages (budburst, floraison, veraison, and harvest). All phenological data indicate that there is a delay in budburst for V-2 of 15 days respect to V-5 and V-6. A delay for floraison also was found for V-2 and V-3 (8 days respect to the others vineyards). In the veraison the delay was for V-1 and V-2 (3 days) respect to other vineyards studied. Significant differences were found in grape composition: total acidity, pH, malic acid, color intensity and anthocyanins. The volatiles also were influenced by the terroir, showed higher concentration of free compounds for V-2 (416 and SW) than the others vineyards and the total bound composition shower the highest values for V-4.

Plastic cover film on table grapes from field to cold storage

Plastic film covering is a technique largely used in viticulture to protect table grapes vines from adverse weather conditions and to reduce the negative effects of grapevine fungi disease. Plastic film composition affects solar radiation income inside the covering with effects on sunlight wavelengths in relation to different absorbance and reflectance. The interaction of selected light ranges with vines could influence grape ripening and yield and consequently influence shelf life.
