| Summary: | The aim of this research is to assess F. angustifolia test tree variability
based on the morphometric traits and shape of samara from the locality
Karapandža. Twenty adult trees were randomly selected. From each individual
100 fully developed samaras were analyzed. The following traits were
analyzed: the length and width of samara, the length of seed, ratio between
the length of seed and samara, the weight of 100 seeds by individual, samara
shape and samara top shape. The obtained results indicated a considerable
variability within the studied individuals at the level of samara
morphometric traits. Considering that all sampled individuals were from the
same populations we could suppose that this variability was not induced by
different environmental factors (climate or soil), then with the existence
of specific genotypes. Classification based on samara size says that our
individuals could belong to large size samaras, i.e. the type known as f.
macrocarpa. However, since there is no uniformity of samara shapes within
the majority of studied individuals we cannot classify them in accordance
with samara shape classification. |
