Grafting with non-suckering rootstock increases drought tolerance in Corylus avellana L. through physiological and biochemical adjustments.

ABSTRACT: Physiological and molecular mechanisms underpinning plant water stress responses still need deeper investigation. Particularly, the analysis of rootstock-mediated signals represents a complex research field, offering potential applicative perspectives for improving the adaptation of fruit crops to environmental stresses. Nonetheless, fundamental knowledge on this subject needs to be widened, especially in some woody species, including European hazelnut (Corylus avellana L). To fill these gaps, we inspected dynamic changes in gas exchanges and stem water potential of two hazelnut genotypes, the 'San Giovanni' cultivar (SG), the non-suckering rootstock 'Dundee' (D), and their heterograft (SG/D), during a drought stress treatment followed by recovery. Biometric and anatomical traits were meas
