Abstract:
In extracts ofCuscuta reflexa ROXB. a cytokinin like factor (CAF = Cuscuta active factor) was found. It was shown that activity of this factor is similar to that of kinetin in all essential points. In tobacco-stem-tissue tests a promotion of growth by CAF was observed. In chlorophyll-preservation tests CAF produced a strong inhibition of chlorophyll dissimilation. Moreover in tests with(14)C-labelled glycine a migration of the glycine and other amino acids due to CAF was found.The occurrence of the observed cytokinin-like factor inCuscuta reflexa is discussed with respect to the parasite-host relations ofCuscuta.
