IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca
IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.
AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.
EnglishGrapevine rootstocks affect the nutritional status of plants and thus the production and the quality of grape. In this study, a screening of mineral level in vine leaves is performed to a series of 35 Vitis hybrids for rootstock selection, in two different growing conditions at two sampling times. Mineral levels were determined by elemental analyzer (N) and ICP-MS (P; K; Mg; Ca; Na; Fe; Cu; Fe) in leave samples. Generally, the effect of growing conditions was predominant, whereas genotype effect and their interaction were significant for N, K, Ca, Mg, Na, Mn and Cu. A cluster analysis was used to identify the affinity of each genotypes to K, Mg and Ca. Furthermore, response of genotypes to the different environments was assessed by a plasticity index. An elastic behavior was shown by 14 genotypes. Within this group, genotypes G.05, G.21, G.71, G.76 and G.77 reported high potassium level, beside the already demonstrated tolerance to water stress.
