DEPISTAREA ŞI IDENTIFICAREA FOCULUI BACTERIAN AL ROZACEELOR LA CULTURILE POMICOLE

Maria MAGHER

Abstract


Focul bacterian, bacterioza, la pomii fructiferi şi la alte plante rozacee poate deveni devastator în livezi şi, prin urmare, împiedică în mare parte dezvoltarea economică. Multe dintre simptomele focului bacterian pot fi recunoscute imediat după infectare. Prin utilizarea mediilor microbiologice speciale, bacteria Erwinia amylovora a fost izolată din eşanţioane de măr, păr şi gutui infectaţi. Prin teste de inoculare a fost confirmată patogenitatea şi virulenţa acesteia la plantele gazdă.

Detection and identification of fire blight in orchards

Fire blight, a bacteriosis of fruit-trees and other rosaceous plants, can be a disastrous disease in orchards and is therefore of great economic importance. Many symptoms of fire blight can be seen during short time after infection. Using special microbiological media this pathogenic bacterium has been isolated from samples of infected apple, quince and apple trees. Inoculation tests confirmed its pathogenicity and virulence to host plants.


Keywords
