INVESTIGATION ON THE MORPHOLOGICAL-PHYSIOLOGICAL CHARACTERISTICS OF SILVER FIR (ABIES ALBA MILL.) POLLEN IN CONNECTION WITH ITS HYBRIDIZATION Summary Very scanty studies on the biology and physiology of the pollen of Silver Fir (Abies Alba Mill.) prompted us to pay special attention to this question, and to determine what are the differences as to the size and shape of Fir pollen grains. In this connexion we were especially concerned with finding out the method of preserving the pollen for as long as possible, achieving at the some time a good germination. We likewise investigated the germination of pollen under various environmental conditions (»in vitro«). All these studies are closely connected to the hybridization of Fir. 1. It was established that the pollen collected from violet male inflorescences are characterized by larger dimensions in comparison with pollen from yellow and intermediate inflorescences (Tabs. 1 and 2), which suggests the existence of lower systematic categories within the Abie alba species. The same differences were noted also in border values (Tab. 3), which implies that also the variability in the pollen from the violet inflorescences is larger. The dimensions of the pollen grains between individual trees in a population also waried. Greater fluctuations were noticed in trees with a violet pigmentation of male inflorescences. |
