“…The two major exceptions are dihydroconiferyl alcohol and N,N'-diphenylurea. The former, originally found in maple (Granath and Schuerch, 1953), is not active in all cytokinin bioassays (Lee et al,, 1981). Hence, it is not considered universally to be a CK.…”

Red pine seedlings alternate between root and shoot production in a periodic fashion. This habit is referred to as episodic growth and is assumed to be con trolled by endogenous plant growth regulators. This project was concerned with the role played by cytokinins in the control of episodic growth. After confirming the existence of episodic growth in red pine seedlings, a car rier solution was optimized and a series of exogenous application trials was con ducted. Only those solutions containing a surfactant and N®-benzylaminopurine (BAP) produced an observable response. Foliar applications of BAP induced the formation of an apical cluster of buds. As the BAP concentration was increased from 2.5 to 200 mg/1, there was a corresponding increase in the number of buds formed. Hypocotyl length and the percentage of the induced buds that elongated

Die Polymerisation von Acrylnitril durch eine Reihe von p‐substituierten Arylsulfonylaziden wurde in Benzollösung im Temperaturbereich von 100 bis 135°C untersucht. Esergah sich, daß die Polymerisationsoeschwindigkeit proportional der Ausgangskonzentration des Acrylnitrils und der Quadratwurzel der Ausgangskonzentration der Arylsulfonylazide war. Es wurde weiter gefunden, daß die modifizierte HAMMETTSche Gleichung anwend‐ bar ist. Die Reaktionskonstante ρ hat den Wert ‐1,0. Aus den Versuchsergebnissen wurde geschlossen, daß die Polymerisation durch das Arylsulfonylimidogen, ein Stickstoff‐Radikal, ausgelöbst wird.
