Abstract

This study investigated the flower structures of a black mulberry population in Tokat province and its surroundings. Of the investigated black mulberry trees of the population, 49% were identified as monoecious-male, 43% as dioecious-female, 5.7% as dioecious-male and 2.3% as monoecious-mixed. Generally, four stamens were identified in male flowers and especially in mixed catkins, 3 or 2 stamens were also identified in male flowers. Female flowers were composed of a long two-lobed stigma and an ovary. Catkin lengths of male flowers varied between 42.7-22.8 mm and catkin lengths of female flowers varied between 24.1-4.3 mm. The number of male flowers per catkin varied between 26.36-10.62 in dioecious trees and 26.3-14.1 in monoecious trees. The number of female flowers per catkin varied between 36.16-13.5 in monoecious trees and between 52.0-15.6 in dioecious trees. There were significant differences in the phenological stages of the flowers. Flowering lasted about 60 days in all genotypes.
