Table 5 Must composition recorded at harvest on SG (susceptible clone R10) and accession 72-096 (resistant). PF = partially sprayed. FS = fully sprayed. Anthocyanins data expressed as mg of malvidin-3-O-glucoside equivalent per g of skin dry weight. Abbreviations: Anth: anthocyanins, Dp: delphinidin, Cy: cyanidin, Pt: petunidin, Pn: peonidin, Mv: malvidin, acyl: acylated, coum: coumarated, glc: glucoside, n.d.: not detected.

From: Canopy physiology, vine performance and host-pathogen interaction in a fungi resistant cv. Sangiovese x Bianca accession vs. a susceptible clone
