| Comparative Presentation for Growth Ability of Aleppo Pine (Pinus halepensis Mill) and Stone Pine (Pinus pinea L.) in Mixed Stands in the »Musapstan« Management Unit Forest Office of Zadar pdf HR EN | 3 | |
| Summary: These studies were carried out in the area of the Forest Office of »Zadar« within the management unit »Musapstan«. The study started in 1976 when experimental plots were established in compartments 11 and 12. The experimental plots were 100 x 100 m in size, namely 1 hectare. In all plots diameter breast height was measured for each tree above 9 cm cross section by means of AEDENBRUCK -BOHMEREEOVE construction rounded gauge. The height of every tree was measured by BLUME — LE1SS hypsometre. On the basis of measurd d b h the structural elements of the stand (N, G, V) were determined and the distribution of d b hs by 2 cm. together with stand height curves, were graphically presented. See Tables 1, 2, 3, 4 and graphs 1, 2, 3, 4, 5, 6, 7 and 8. The first measurings were carried out in 1976 and the second in 1991. Thus, the plantation trees were measured in the fourtieth and fiftieth year. The plantations were raised on a characteristically Karst terrain. The soil was terra rosa, luvic, colluvial, clayey (Škorić, 1979). Rockiness of the terrain ranges from 40 to 90%. Phytocoenologically these studies are concerned with the plant association of Pubescent Oak and Oriental Hornbeam. Ecologically this area belongs to the warm zone of the Pubescent Oak and Oriental Hornbeam forests (Queco — Carpinetum orientalis H-ić 1939, Rauš 1987). With regard to climate this area has a Mediterranean climate. With regard to the Karst factor by M. Gračanin the climate changes monthly. Thus, the months of January, February, 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. | ||
