| Abstract:
Apricot apoplexy is quite frequently met with in apricot orchards all over the world, causing serious damage indicated by a gradual withering of trees and sudden withering of leaves. Apricot apoplexy is considered by most researchers dealing with its etiology (Dvorak, 1963; Majernik, 1963; Rozsnyay, 1963; Klement 1977) to be the result of a complex of abiotic and biotic factors which have a chain-reaction which is difficult to discover which is the main element (Klement, 1977). Under favourable agricultural soil and climate condition a number of pathogens of the Mycoplasma type bacteria and fungi can easily penetrate the apricot tree finally causing early tree withering (Morvan, 1977). Among the pathogen fungi frequently isolated from the trees, branches and trunks which are withering in apricot plantations in Romania, we can mention: Cytospora cincta, Eutypa armeniacae, Stigmina carpophila, Monilia laxa, Conyothirium amygdali. Beside these fungi, the apricot-tree in our country is attacked by some other pathogens: Alternaria tenuissima, Tranzschelia pruni-spinosae, Gnomonia erythristoma. In this paper we shall present our results on the impact of some agro-technical measures on infection and development of main apricot diseases. | |
