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.
