The susceptibility to Armillaria mellea of different Prunus species used as stone fruit rootstocks
Four trials were started in 1980 to investigate the level of resistance to Armillaria mellea sensu stricto within plum species ( Prunus domestica, Prunus insititia, Prunus cerasifera) and recently created rootstock clones originating from interspecific hybridization. The results either revealed for...

Summary: | Four trials were started in 1980 to investigate the level of resistance to
Armillaria mellea sensu stricto within plum species (
Prunus domestica, Prunus insititia, Prunus cerasifera) and recently created rootstock clones originating from interspecific hybridization. The results either revealed for the first time or confirmed a previously observed high degree of susceptibility shown by certain rootstocks: peach, almonds, peach × almond, peach ×
Prunus besseyi, peach ×
Prunus davidiana, peach ×
Prunus kansuensis. The most tolerant rootstocks were found within the species
P. domestica, P. insititia, P. cerasifera (cultivar ‘Myrobalan’) and among hybrids with these species. Defence reactions in the bark and sapwood of tolerant rootstocks were observed. Environmental factors and type of scion had some influence on the expression of tolerance or susceptibility. |
