[The chlorophyll content of tumors from pale and green leaf tissues of Kalanchoe fedtschenkoi].
Pale and green leaves of Kalanchoe fedtschenkoi var. variegata were inoculated with Agrobacterium tumefaciens. Six weeks later the chlorophyll contents of the leaves and their tumors were investigated. The tumor tissues possess very similar concentrations of chlorophylls and a low number of chloroplasts per cell. Thereby they differ from each of the initial tissues. The qualitative composition of pigments (chlorophylls and carotenoids) of the 4 tissues is the same.
