VIABILITY, GERMINATION AND AMOUNT OF POLLEN IN SELECTED CAPRIFIG TYPES

MURUVVET ILGIN, FUAT ERGENOGLU AND SEMIH CAGLAR

Abstract: Pollen quality of 5 caprifig genotypes selected in the East Mediterranean Region was determined. Triphenyltetrazolium chloride (TTC) and fluorescent diacetat (FDA) test procedures were used in evaluating pollen viability. Germination of pollen was determined by using various concentrations of sucrose supplemented with H₃BO₃, KNO₃ or GA₃ in agar medium. Pollen production status of caprifig flowers was determined. The percentage of viable pollen in caprifig types ranged from 76.04 to 83.34% by TTC test and from 75.60 to 86.73% by FDA test. The germinations were higher on the media containing 20% sucrose and increased up to 74 % with the addition of H₃BO₃ or KNO₃, but not GA₃. The number of pollen per flower ranged from 4355 to 7169 grains. The selected caprifigs appeared to be satisfactory pollinators in respect to criteria investigated.
