| Abstract:
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. | |
