Description

Pollen grains of Pinus Silvestris were irradiated with UV-rays, and the stimulation, or restraint of gemination was studied. Gemination of the pollen was retarded by irradiation of the nucleus. This book place proportionally to the increasing doses: The conditions of irradiation and the effects of the stimulation and retardation are described in detail. Different dose rates with different effects on nucleus and cytoplasma are observed. (AJ)

Abstract (German)

Pollenkoerner von Pinus Silvestris wurden mit Ultravioletstrahlen behandelt und die Stimulation bzw. Hemmung der Auskeimung untersucht. Durch Bestrahlung des Nucleus wurde proportional zum Anstieg der Dosis das Auskeimen der Pollen gehemmt. Bestrahlungsbedingungen und Stimulations- bzw. Hemmeffekte werden im einzelnen beschrieben, wobei unterschiedliche Dosisraten mit unterschiedlichen Wirkungen bei Nucleus und Cytoplasma beobachtet werden. (AJ)
