TYPES OF BLOOMING SEQUENCE OF FLOWERS IN THE INFLORESCENCE OF PEAR VARIETIES

Structure of the inflorescences and the blooming sequence of flowers within the inflorescence have been studied in an assortment of pear varieties.
In the major part of varieties (61%), the sequence of blooming was centripetal (beginning with the first flowers of the raceme), whereas in 23 %, the sequence followed a centrifugal order.
A divergent type of blooming was characteristic for 16% of the varieties.
There was a tight connection between the blooming sequence and the number of flowers per inflorescence as well as the occurrence or frequency of side-inflorescences.
