 In: Acta Botanica Neerlandica v. 31, no. 1, p. 105-11182-822021Summary: Pollen grains from four pollen source genotypes (H55, Oh43, K64 x K55, Ky49 x Ky27) were cultured on an artificial medium (15 sucrose, 0.6 bacto-agar, 0.03 calcium nitrate, 0.01 boric acid) supplemented with four concentrations (0, 5, 25, 100 ppm) of gibberellin A(,3) (GA(,3)). At 1, 2, and 3 h after inoculation, germination percent and pollen tube length were measured. A highly significant concentration x pollen source genotype interaction for germination percent was obtained. Depending on the pollen source genotype, increasing GA(,3) concentrations either increased, decreased, or had no effect on pollen tube length. Any stimulatory effect of GA(,3) on
