The Characteristics of the Diameter Growth and Increment of the Trees in the Stands of the Narrow-leaved Ash and the Introduced White Ash in Central Posavina     pdf     HR     EN 145
Summary: The research was carried out in two middle-aged mixed stands of narrow-leaved ash and white ash aged 54 and 50 years in the area of the forest offices Nova and Stara Gradiška. The recordings of stand structures in the locality of the forest office of Nova Gradiška showed the mean stand diameter of 30.9 cm in the 54-year-old stand at an altitude of 94 m. In the locality of the forest office Stara Gradiška situated 104 m above sea level, the mean stand diameter was 22.7 cm.Samples of increment cores of 12 cm in length were taken for narrow-leaved ash and white ash from the trees belonging to the diameter degree of mean basal area trees. The increment cores were analysed by measuring the width of every individual ring by a tenth of the millimetre. The thickness of the bark was also measured. The results obtained from the analysis of the increment cores gave the trends in ring widths for individual trees, as well as the trends in average ring widths within individual samples in the last 35 or more years. Also, on the basis of the increment core analysis, parts of the diameter growth curve of the mean stand tree for every studied species were obtained. The method is described in the paper.
According to the results, the diameter growth was equal in both species in the first period of life, that is, in the first 15 years, followed by a more rapid growth in the diameter of narrow-leaved ash in relation to white ash. In other words, the diameter increment of narrow-leaved ash was higher during the studied period, which indicates better conditions for the growth of the autochthonous narrow-leaved ash.

Key words: narrow leaved ash (F. angustifolia Vahl); white ash (F. americana L.); growth of mean stand diameter; radial increment
