Influence of rootstock on drought response in young ‘Gale Gala’ apple (<i>Malus domestica</i> Borkh.) trees

Abstract

'Gale Gala' trees' response to drought stress was associated with the rootstock's genotype onto which it was grafted. Trees with M. sieversii as rootstock are more drought resistant than trees with M. hupehensis as rootstock, which suggests that M. sieversii can be widely used as rootstock in arid and semi-arid regions.
