Following the results obtained, these conclusions occur:
• The present equations go with the pattern of variation of the previously presented
diameters
• The most significant variations of the radial growths occur in mixed stands
• The equations can be used in the previously established conditions to establish
relative radial growths at other stands, which vegetate in similar environmental
conditions in the middle basin of the Crisul Repede river
• The equations are viable only locally, in other areas, they need to be verified by
further research
• These equations were elaborated for even-aged stands, their applying to relatively
even-aged stands must be verified.
