Lifestyles of Colletotrichum acutatum. Olivicoltura 91—5. All the tree tomato isolates were identified as C. Three recent studies carried out by Corpoica examined the survival strategy and population structure of the anthracnose pathogen C.

Las conidias son hialinas claracon forma de media luna y unicelulares Figura The variation coefficient for the spore germination experiment was moderate to high Colletotrichum gloeosporioidesa new olive Olea europaea L.

La Antracnosis del olivo y su efecto en la calidad del aceite

Tree tomato isolates formed orange colonies with a rather flattened mycelium, and grey or white bottom color. In this study, overall spore germination levels were low, suggesting that the fungus may have unidentified internal constraints or regulatory mechanisms for survival similar to spore dormancy, as described for citgicos plant pathogens De Wolf and Isard, Aunque en Portugal la especie C.

However, the morphology of Colletotrichum colonies varies within and among groups, depending on culture medium, substrate and temperature, among other factors Contreras, The pathogen was recovered and re-isolated from the infected tissue, thus proving that this species is the anthracnose infectious agent in this crop.

Evidence of early flower infection in olives Olea antrafnosis by Colletotrichum acutatum and C. Effect of plant extracts and time of application on incidence of anthracnose, yield and quality of mango. Controlling Colletotrichum is still a deficient task, as is our knowledge about the basic aspects of its biology such as the infectious agent and its genetic variability, inoculum dispersal and host specificity one single Colletotrichum species has been found causing crossed infection on several hosts.

Agraria 7— Triacylglycerols composition and volatile compounds of virgin olive oil from cv. Cultural characteristics, pathogenicity, and host range of Colletotrichum gloeosporioides isolated from olive plants in Montenegro. Characterization of the causal agent of olive Anthracnose in southern Italy.

Once in the laboratory, petals were chosen to be disinfected in a 0. Effects antracnisis temperature, leaf wetness duration, and inoculum concentration on infection of annual bluegrass by Colletotrichum graminicola. Isolates coming from tree tomato showed several types 0, 1 and 2; or 0 and 1. Abang found category SGG fungi to be the most aggressive ones, due to the degrading enzymes they posses, which are capable of destroying the cell membranes of young plant tissues.


Again, the original pathogen was re-isolated from the infected fruits. antracnosks

Four exploratory tests were initially carried out in with four microbial groups bacteria, fungi, actinomycetes, yeastsresulting in 14 isolates being selected for further testing against the pathogen C. De las 31 especies del complejo C. Three hundred and fifty one Merck PDA grown Colletotrichum isolates were obtained from anthracnose affected organs Antdacnosis lime flowers, and mango and tree tomato fruits citrixos, collected in different productive provinces 3 of Colombia Tab. The results of the two tests were interpreted according to the classification chart shown in Tab.

The effects of C. Agricultura— The latter assessed infectivity on both the original hosting crop and the other two crops crossed infectionby putting the fungi in contact with organs taken from the three fruit crops. El olivo Olea europaea subsp. The appressoria of Colletotrichum graminicola and C.
