The aim of the studies carried out in the period 19941996 was to
determine the relationship between the growth indices of young pear trees
grafted on two kinds of quince (Cydonia) rootstock (S1 and MC) and Caucas
pear. Growth vigour of the trees was
determined by means of the following biological parameters: trunk diameter
or circumference, the number of oneyear shoots, the total length of
annual shoots, the number of flowers and the number of fruits. In order to assess the usefulness
of cultivarrootstock combinations an attempt was made to use
Multidimensional Comparative Analysis (MCA). As a result the particular
cultivarrootstock combinations were ranked according to their growth
vigour. It was found that vegetative
growth can best be defined by means of the following biometric
characteristics: the crosssection area of the trunk and its increase, the
number of annual shoots, the total length of annual shoots, and the
average length of those shoots.
