Abstract


THE PHYTOPATHOLOGICAL STATE OF ASH TREE AT THE «OLEKSANDRIA» STATE DENDROLOGICAL PARK OF THE NATIONAL ACADEMY OF SCIENCES OF UKRAINE

Abstract. We conducted the phytosanitary inspection of Fraxinus excelsior L.  plantations in the “Alexandria” park. In one-third of old-growth (100–200 years) ash trees we detected pathology (frost cracks, hollows, tumors, ulcers, fruiting bodies of fungi), which, however, led to the death of trees. Among of the young and middle-aged trees are icing of annual shoots, leaves lesions by powdery mildew and brown spot, defeat trees infectious necrosis.

Since 2011 occurred drying of middle-aged trees, which in morphological characteristics similar to the disease Chalara fraxinea. Just during 6 years dried 41 trees, including 23 during the last 2 years, hundreds of trees in the park still have a typical symptoms for Chalara fraxinea disease. The biggest center of drying of is in the upper Eastern beam, which withered away 22 ash trees, 18 of them during the last 2 years.

Over the past few years as a part of old-growth oak noticeably reduced the number of the F. excelsior undergrowth. It is necessary to confirm the presence of Chalara fraxinea disease in the park using molecular methods or macroscopic characteristics. The necessary are the measures directed at eliminating the factors of weakening of ash trees.

Keywords: “Olexandria” dendrological park, Fraxinus excelsior, phytosanitary inspection, pathology, drying of, Chalara fraxinea, Hymenoscyphus fraxineus.
