Phytochemical characterization and effects on cell proliferation of Pinus nigra Arn. bark.

Pinus nigra Arn. bark extracts from Mokra gora (MG) and Tara mountains were analyzed with regard to their polyphenolic profile and antioxidative and antiproliferative activity. The ethanol extract from MG showed the highest phenolic, flavonoid, tannin, and proanthocyanidin content when compared with the acetone and methanol extracts from both sites.

Development of Pathogenic Symptoms in Juvenile Trees.

When monitoring the state of health of trees, unusual symptoms were discovered within a plantation in Bosnia and Herzegovina. These symptoms included the appearance of necrosis and cankers in the basal parts of the trees, followed by the formation of fruiting bodies, however, none of these symptoms were found in the crowns. After sampling and isolation of the necrotic parts from the stem base, pathogen was isolated and identified from the characteristics of pure cultures, morphology of the fruiting bodies, and from multilocus sequencing.
