Effects of Phaeomoniella chlamydospora ana Phaeoacremonium aleophilum on grapevine rootstocks

cuttings of five grapevine (vitis vinifera) rootstocks were wounded and immediately inoculated with suspensions (approximately 5x103 conidia- ml-1) of either phaeomoniella chlamydospora, phaeoacremonium aleophilum or a mixture of both species. the presence of these endophyte fungi affected the quality of each of the five rootstocks. among the roostocks investigated in this study, 1103p and 101-14 mg were less susceptible to the infection caused by pa. chlamydospora wd pm. aleophillum.
