The
aim of this research is to determine the rate of pollen germination and pollen
production of 29 hybrid walnut genotypes. For this aim, the germination
percentage of the pollens was examined by using the agar in the petri and
hanging drop methods. Pollen production amount of the genotypes was determined
with the hemacytometric method. The highest germination ratio of genotype 30
was obtained by the agar in the petri method in 1% agar+10% sucrose (54.65%).
In 15% sucrose concentration in the hanging drop method, which is the best
medium for all 29 hybrid walnut genotypes, pollen germination rate was 51.84%
(genotype 9). The amount of pollen in a flower and an anther is very high in
all genotypes. The consequence indicates that different
treatments had a significant effect on the germination percentage. As a result
of the findings obtained from this study, genotypes can be used as a
pollinator.
