| mechanisms governing the responses to anthracnose pathogen in juglans spp. | juglans nigra and juglans regia are two highly economically important species for wood and fruit production that are susceptible to anthracnose caused by gnomonia leptostyla. the identification of genotypes resistant to anthracnose could represent a valid alternative to agronomic and chemical management. in this study, we analyzed 72 walnut genotypes that showed a variety of resistance phenotypes in response to natural infection. according to the disease severity rating and microsatellite finger ... | 2011 | 21884735 |
| severity of walnut anthracnose and its relatively resistant in iran. | walnut black spot or anthracnose has been a destructive disease of juglans in iran mainly northwest of the country. current situation of the disease was studied in various regions including qazvin, zanjan, hamedan and east azarbyjan provinces during 1999 to 2002. infected samples such as leaves, fruits and foliage were collected and cultured in pda, cma and na media after surface sterilization with sodium hypochlorite. morphological characteristics and asexual reproduction of isolated pathogen s ... | 2006 | 17390889 |
| phytopatological problems and solutions in the walnut orchards along lake balaton. | european or persian walnut (juglans regia) is an important and healthy food as well as base material of timber industry. several pests (pathogens and insect pests) may cause serious damages on walnut. these are less known on the crop land of the tree. results of some years of our experiments including bacteriological and mycological studies, are presented in this paper. the optimum time of chemical protection against the walnut blight (xanthomonas arboricola pv. juglandis) was determined. occurr ... | 2007 | 18396807 |
