Field susceptibility of four peach rootstocks to Phytophthora citrophthora and P. syringae
Phytopathologia Mediterranea 39 (3), 404-409
Abstract: Four two-year-old peach rootstocks were assessed for susceptibility to Phytophthora citrophthora and P. syringae. Peach rootstocks reacted differently to each Phytophthora species. GF677 rootstock was the less susceptible to P. syringae. The other rootstocks inoculated with this fungus did not differ significantly in the average necrosis length produced. Also peach rootstocks inoculated with P. citrophthora showed different level of susceptibility. Inoculation of GF677 plants with P. citrophthora produced the largest necrosis of all rootstocks tested. There were no significant differences in the lesion lengths of PR204, GF305, and KID I plants. The results from laboratory experiments with both fungi were similar to those from the field experiments: any observed differences can be attributed to differences in the physiology of the plant tissues and in the aggressiveness of the fungi.
