Hausdurchsuchung und Beschlagnahme,y to air pollution. It is our contention that air pollution has contributed to major changes in the genetic structure of many such forest ecosystems. Natural selection against sensitive species and individuals within species has long been known to occur near major point sources of air pollution such

https://doi.org/10.1007/978-3-642-91662-5r a series of experiments Herzynic-Carpathian provenances were used, each comprising open pollinated single tree progenies, the siblings of which were propagated vegetatively by cuttings. These clones were fumigated with HF, SO., and O. and anatomical, morphological and physiological traits were ass

Shoot and root growth were suppressed by about 50 %. Aluminum sensitivity was independent of the geographic co-ordinates and of the altitude of the

Lokale Chemotherapie der Basaliome birch in a range wide provenance trial were shown to be conservative over a wide geographic area of North America. This lack of variation may indicate that pH may be important in the pollen stigma interaction in this species whose pollen would be at risk at pH’s < 3.7. White birch (.) was shown to
