Summary


COMPARATIVE INVESTIGATIONS ON THE GROWTH RATE OF SCOTS PINE
(PINUS SILVESTRIS L.) AND BLACK PINE (PINUS NIGRA ARN.) IN THE
ARBORETUM »SLATINA« OF THE FORESTRY FACULTY IN SARAJEVO


In the Arboretum »Slatina« belonging to the Faculty of Forestry in Sarajevo
was examined the rate of growth of Black Pine from Bugojno (Bosnia) and of
Scots Pine originating from Tfebona (ČSSR) both 18 years of age. The culture
of the mentioned Pines lies at an altitude of 640—670 m and has a western aspect.
The parent material is formed of clay and clayey marl, and the soil is deep, heavy-
textured and of variable humidity, possessing a poorly permeable B-horizon. The
site belongs to the forest community Erythronio Carpinetum illyricum Horv. et al.
1974.


Studying the growth rate the authors came to the following conclusions:


—
the upper heights of Scots Pine are by ca. 5 % greater than those of Black
Pine. These differences are significant at p = 0.001;
—
the mean height increment in the last 10-year period amounts to 54.7 cm
in Scots Pine, and to 51.4 cm in Black Pine; although the differences are
small, the dynamic of the growth rate is different;
—
the mean diameters b. h. in Scots Pine are 68.7 mm, and in Black Pine 91.6
mm. The mean diameter of 20 %s of the thickest stems in Scots Pine is
111.2 mm, and in Black Pine 128.9 mm, while the differences in Scots Pine
are significant at p = 0.01;
— the basal area in Scots Pine amounts to 17.53 m2/ha, in Black Pine to 31.87
m2/ha. Having in view that the differences in the heights and height increment
are small, and that the diameters and basal area in Black Pine are
considerably greater, it follows that up to the 18th year Black Pine is considerably
more productive.
