Abstract

Grapevine 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.
