Kurzfassung:
Pollen quality of horse chestnut, expressed as pollen productivity, viability
and germination was studied. Anthers of horse chestnut genotypes had pollen
production from 3.66 to 5.06 x 103 pollen grains per anther, depending of
genotype. Also, pollen of horse chestnut Ah1-Ah4 genotypes showed different
viability (from 56 to 68%), after staining with fluorescein diacetate.
Pollen germination of Ah1-Ah4 genotypes varied from 50-66% on basic medium.
Inclusion of polyethylene glycol-PEG from 10%, 15% and 20% v/w increased
pollen germination. The best results were achieved on medium with the
largest PEG concentration. On these medium 76-91% pollen grains were
germinated, depending of genotype. The best pollen quality, for all tested
parameters, had genotype Ah2. Knowledge about morphology, production,
viability, in vitro germination, tube growth as well as pollen: ovule ratio
can be of great importance for future pollen biology studies.
