The Monitoring of Bark Integrity from Phytosanitary Point of View on Plum Trees Plantations in Reghin Area

Abstract

A special importance in long developing of plum is the health of the primary elements of stem and main branches structure. The bark injuries (wounds) may be of mechanical or pathological origin or a combination between these. Monitoring consisted in investigating a great number of affected trees from Reghin area, the number of injuries that damage them and type of injuries: lesions without Stereum purpureum and Phellinus ignarius infection or lesions infected with these fungi; lesions with or without callus. The observed cultivars were commonly found in the Reghin area: de Bistrita, Stanley, Anna Spath and Silvia. In the present paper, we can say that in all four plantations the highest percentage of lesions observed were without infection but from the infected wounds Stereum purpureum was the most encountered fungus.
