Modifications Induced by Rootstocks on Yield, Vigor and Nutritional Status on <i>Vitis vinifera</i> Cv Syrah under Hyper-Arid Conditions in Northern Chile

Abstract

Hyper-arid regions are characterized by extreme conditions for growing and lack of water (V. berlandieri genetic background should be used in Syrah growing under hyper-arid conditions to maintain adequate levels of plant vigor and to avoid deficiencies or toxicity of macro and micronutrients.
