Ink disease caused by the root-rot pathogen P. cinnamomi (Pc) threatens European sweet chestnut (Castanea sativa Mill.) orchards, and growers increasingly graft susceptible C. sativa traditional varieties on Pc-resistant hybrid commercial rootstocks. The influence of the scion, the rootstock, and grafting per se on the vegetative budburst, growth, susceptibility to Pc and defence-related hormone profile of Castanea spp. are unknown. In a greenhouse experiment, these effects were evaluated by reciprocally grafting two Pc resistant C. crenata x C. sativa clones and two Pc susceptible C. sativa clones. Resistance to Pc and the hormone content of leaves and roots were rootstock-dependent, and survival rates of susceptible chestnuts strongly increased when grafted on resistant rootstocks. The scion had no effect on the resistance to Pc and the hormone profile of leaves and roots of grafted trees, but influenced vegetative budburst and primary growth. Grafting per se increased susceptibility to Pc and altered the defence-related phytohormone content of trees, especially in resistant rootstocks, but did not influence budburst and growth of trees. Grafting-induced alteration of the constitutive defense-related hormone profile could explain the increased susceptibility of resistant rootstocks to Pc. Nine days after infection, a dynamic hormonal response consisting of decreased jasmonates (JA and JA-Ile) in leaves and increased ABA and JA-Ile in roots was observed in resistant chestnuts. This is the first study addressing the role of grafting in modulating resistance to the soil-borne pathogen Pc in chestnut trees. [-]
