摘要:

AbstractBacteria, yeasts and other fungi were isolated from stem and root wood of Norway spruee trees with disease symptoms and were identified in order to evaluate a possible mierobial involvement in the widespread tree decline in Central Europe.

摘要:

AbstractIn spite of numerous aeroplane flights and different incerpretations of the infrared colour photographs obtained, the remote sensing of root rotting fungi of rubber tree has failed in practice in the Ivory Coast. The reasons for this failure and conclusions on the efficiency of this method are discussed.

摘要:

AbstractA literature survey is given of the five European honey mushroomsArmillaria mellea, A. borealis, A. bulbosa, A. cepistipes, and A. obscura (syn. A. ostoyae)(corresponding respectively to Korhonen's intersterile groups D, A, E, B, and C); two forms of A.cepistipesare discussed: the tiny A.cepistipes f. cepistipesfrom Czechoslovakia and West Germany and the more common A.cepistipes f. pseudo‐bulbosaRomagnesi et Marxmüller. Nomenclature, geographical distribution, hosts, some characteristics, and practical importance (including pathogenicity) are treat

摘要:

AbstractWounding of excised roots of Norway spruce [Picea abies (L.) Karst.] caused a rapid accumulation of phenolic compounds, decrease of starch content and of certain enzyme activities in the ray cells. Infection of the wounds byHeterobasidion annosum(Fr.) Bref. intensified these processes, caused oxidation of the phenols, and induced activity of acid phosphatase and β‐glucosidase in the ray cells of the infected area. The reactions were oxygen‐dependent. Intra‐ and extracellular enzymes were detected in the wood‐infecting hyphae. Other wood‐growing fungi caused similar reactions in the wood as

摘要:

AbstractResistence tests on poplars raised by tissue culture.The possibility of testing poplar clones for susceptibility to poplar canker at an early stage was tested by inoculating plants, produced by tissue culture, at 1.5, 2, 4 and 6 weeks and 7 months. Results were positive and compared well with standard tests.

摘要:

AbstractThree simplified freeze drying methods have proved partieularly successful for the long‐term conservation of phytopathogenie fungi. Tests revealed no loss of vitality after up to 25 years of storage. The determination of the maximum lethal temperature allows the storage life of lyophilised fungi to be estimate
