VĂCĂROIU, C.R. ZALĂ, STELICA CRISTEA, MARIA OPREAUniversity of Agronomic Sciences and Veterinary Medicine of BucharestKeywords: Stigmina carpophila, pathogen, biologyAbstractThe Stigmina carpophila (Lev.) B. Ellis (sin. Cotyneum beijerinckii Ouedem,Clasterosporium carpoplilum (Lev.) Adelhold), teleomorf a Ascospora beijerincki Vuill.,fungus produces diseases to the plant's leaves and stains the fruit of the pits, which attackwith different intensities the peach, the apricot, the sour cherry tree, the cherry and theplum.Depreciating quality of the fruit are the first symptoms of the disease, then, through thegrowth of the attack degree, early defoliation appears, which leads to the trees' weaknessand in the end to their decline.In Romania, this fungus is quite outspread, being very common in less attended meadows, ifthey are not protected from this fungus. This pest causes great losses in the years withfavorable weather conditions.An important aspect is researching the biological parameters of this fungus.The biological material used was typified by the leafs, shoots, fruit, flowers and buds of thekernel species.The pathogen's isolation was made on a crop area formed of potato-corn syrup -agarCGA).398

VĂCĂROIU, C.R. ZALĂ, STELICA CRISTEA, MARIA OPREAUniversity of Agronomic Sciences and Veterinary Medicine of BucharestKeywords: Stigmina carpophila, fungus, nitrogen sourcesAbstractStigmina carpophila (Lév.) is a fungus which induces a certain disease, which destroys theleafs and stains the fruit.This disease is displayed on the leaves, fruit and young scions, but the most importantdamage is provoked on the tree branches, this being a reason for which the gardeners areforced to pick out whole branches every year, so that, after 7-10 years, in that specific treeonly a few branches remain, with weak growth and minimum fruit production.It is often met in all trees which make fruits, and the largest losses are ecountered inapricot and peach.The intense attacks appear in rainy springs, which follow after gentle and soft winters,when the reproductive organs resisted in a very high number.In this project we observed the Stigmina carpophila fungus behaviour under the pHinfluence, growing on certain crop environments and the transformation of some carbonand nitrogen sources.The biological material used was displayed by the leaves, the scions, fruit, flowers andburgeons of the tree species.Isolation of the pathogen was made on a crop field which was frequently used, formed ofpotato-glucose-agar (CGA).404
