Abstract :
[en] Vitrification of carnation tissues by passage from solid to liquid medium was accompanied by decreased lignin content. The higher lignin level of normal tissues corresponded to a higher phenylalanine ammonia-lyase activity. It also paralleled a much higher activity of soluble and wall peroxidases towards syringaldazine. Kinetical analysis of soluble isoperoxidases indicated a two-step control of basic and acidic enzymes with a diminished activity of the latter in glassy plants. Compartment analysis of guaiacol peroxidases showed a different distribution in malformed tissues.
