The variability of viability (germination rate and the length of pollen
tubes) of fresh pedunculate oak (Quercus robur L.) pollen grains was studied
in vitro on a medium containing 15% sucrose. Spatial variability was studied
by sampling fresh pollen grains from a total of thirteen trees at four
different sites in the area of Belgrade (Košutnjak, Banovo Brdo, Ada
Ciganlija and Bojčin Forest) in a single year (2011). In order to assess
temporal variability and determine the effects of climate change on a small
time scale, we studied the viability of the pollen grains collected from one
tree at the Banovo Brdo site in six different years (2004, 2005, 2006, 2007,
2011 and 2012). Interindividual variability was tested on the pollen grains
sampled from eight trees at Ada Ciganlija in 2004. The percentage values of
the pollen grain germination rate and the pollen tube length showed no
statistically significant differences between the sites. However, the studied
characteristics of the pollen grain viability (germination rate and pollen
tube length) showed statistically significant differences in both temporal
(between the pollen collection years) and interindividual variability. This
type of research makes a valuable contribution to pedunculate oak breeding
programs through the identification of trees with stable production and a
good quality of pollen. Furthermore, it can be important in defining the
patterns of spatial, temporal and individual variability of pollen grain
viability under the influence of climate factors, which are showing
compelling changing trends from year to year. |
