A. Tomašević: KOMPARATIVNI PRIKAZ USPIJEVANJA ALEPSKOG BORA (PINUS HALEPENSIS MILL) I PINIJE... Šumarski list br. 1-2, CIX (1995), 3-13 ry, October, November and December display characteristics of a humid climate. The months of March, April, May and September are characterized by a semihumid climate. The months of June, July and August have the characterisics of an arid climate, as in this period there is almost no precipitation. Structural elements of the stands (N, G, V) are shown in Tables 1, 2, 3 and 4. Table 5 presents various parameters for both measurings in compartments 12 and 16. Research was carried out in mixed plantations of Aleppo Pine and Stone Pine. Compartment 12 includes 77% of Aleppo Pine and Stone Pine 18%. Compartment 16 includes 33%o of Aleppo Pine and 57% Stone Pine. D b h distribution is shown in Graphs 1, 3, 5 and 7 and a shift to the right is visible, i.e. they have a tendency to right asymmetry. Height curve is given in Graphs 2, 4, 6 and 8, and it can be seen that height increment for both species is still very active, even in the 55th year. Average volume of wood per one tree in compartment 12 amounts to 0.95 m3, and 0.91 m3 in compartment 16. Mean height for mean d b h is greater in compartment 12 than in compartment 16. It is assumed that this can be explained by the different mixture retion of Aleppo Pine and Stone Pine. |
