Suppression of female flowers and pollen fertility of male flowers of banana plants
Abstract The objective of this work was to evaluate the effect of the suppression of female flowers on the pollen fertility of male flowers of banana plants. Two modes of female flower suppression, one partial and one complete, were applied shortly after flowering to diploid, triploid, and tetraploi...

| description | Abstract The objective of this work was to evaluate the effect of the suppression of female flowers on the pollen fertility of male flowers of banana plants. Two modes of female flower suppression, one partial and one complete, were applied shortly after flowering to diploid, triploid, and tetraploid banana genotypes. The effect of flower suppression on the number of male flowers and the length of their anthers was evaluated, as well as pollen viability and the size and number of pollen grains per anther. Pollination tests were performed to evaluate the number of seed obtained from the progeny of some genotypes. The total suppression of female flowers significantly increases pollen fertility, estimated by an increase in the number of pollen grains per anther (up to 80% per anther). Total female flower suppression also improves significantly seed production in the crosses (from 35 to 160% per pollinated bunch), which suggests a positive influence of the sap flowing through the bunch on the efficiency of banana pollen. |
