Response to Water Stress of Eight Novel and Widely Spread Citrus Rootstocks.

ABSTRACT: Drought is a problematic abiotic stress affecting citrus crops in the Mediterranean basin and the rootstock plays a fundamental role in adopting adaptive mechanisms in response to water deficit. The aim of this study is to evaluate the response of eight rootstocks under three treatments imposed: control (100% of reference evapotranspiration, Et₀), 66% Et₀ and 50% Et₀. The rootstock genotypes studied were C35 citrange, Bitters, Carpenter and Furr which have been recently spread and so far, little investigated, while others have been widely used especially in the Mediterranean citrus industry, i.e., Citrus macrophylla, C. volkameriana, Swingle citrumelo and Carrizo citrange.
