摘要:General aspects of Swiss late- and post-glacial plant immigration patterns are briefly discussed. The following
examples are mentioned: Ericaceae, <i>Plantago alpina,
Pinus cembra</i> and <i>Picea abies</i>. The history of flora and
Vegetation provides important palaeoecological informations. Moreover, it gives evidence to the stability and
age of quaternary plant communities and serve as criteria
for gene conservation in situ. Finally, the knowledge of plant immigration ways can be a valuable source of plant breeding research.
