|Summary: The research of the diameter growth and of the hight of the trees in the oak and hornbeam community, as well as of that of oak with Genista tinctoria and Carex remotae include the measuring of the trees in the stands of the 5th age class in a part of the basin of the river Česma.Based on the analysis of the measurement data, the following conclusions can be made:|
1) Through a dendrochronological analysis the existance of the changes in the growth of the oak and ash trees in the period between 1964 and 1993 was identified. The increment had a positive growing trend in the first two decades, while in the third decade the oak trees still grow well and the line of the equation constantly runs paralel to the x-axis. In comparison between the two directions of the growth of the oak we can see bigger increment in community in the oak and Genista tinctoria in the period between 1964-1973. In the next period between 1974-183 and 1984-1993 the values of increment of oak trees were bigger in typical forest of the pedunculate oak and hornbeam.
The growth of ash trees is higher in association Genisto elatae - Quercetum roboris caricetosum ramotae, Horvat 1938, but it had the tendency of falling down ten years ago.
Decreasing of increment in the following years: 1966, 1971, 1973, 1975, 1976, 1977, 1978, 1979, 1981, 1983, 1989 and 1990 is bound with the climate conditions and because of low level underground water in vegetation period which is dependent of the quantity of rain. Hydraulic land-reclamation and improvement have had big influence for the basin of the river Česma.
2) Examining of the diameter growth through regression analysis proved a strong linear connection with diameter for all trees in the tested associations. We have seen the difference between oak and ash trees in two associations. Regression constants were negative for oak trees in both associations, but proved bigger in typical forest of the pedunculate oak and hornbeam. The values of ash trees were bigger in the stands of oak with Genista tinctoria and Carex remotae. All data were presented with parabola too, but it wasn,t neccessary because of the strong linear connection.
3) The hights of the trees were similar, but there existed significant difference, because the height of oak trees was bigger in typical forest of the peduncule oak and hornbeam. The ash trees achieved bigger values in the stands of oak with Genista tinctoria and Carex remotae.
4) Presentation of the diameter growth and diameter class produced the following conclusions:
a) Correlation between the breast height diameter and diameter growth was very strong for oak trees. That correlation has weakened for the ash trees.
b) Increment of trees in diameter class 21-40 cm was decreasing, because those are pressed trees in the stands of the 5th age class.
c) The diameter increment of oak trees was increasing constantly in diameter class 51-60 cm. That trees proved the best trees in the measuring stands.
d) The oak trees above 60 cm were growing and continue to grow, but the ash trees are decreasing. The ash trees were earlier physically mature in the 5th age class. That conclusion come out from the research of ours scientists Fukarek (1954), Benić (1953, 1954) and Plavšić (1954, 1956, 1962). They proposed shorter rotation for the European ash, because that is the only way to have a good stem and annual ring over 3 mm.
