W. Bar et al., INTRASPECIFIC AND INTERSPECIFIC ALLELOCHEMICAL EFFECTS IN 3 KALANCHOE-SPECIES (CRASSULACEAE), Zeitschrift fur Naturforschung. C, A journal of biosciences, 52(7-8), 1997, pp. 441-449
The intra-and interspecific acting allelochemicals of Kalanchoe daigre
montiana, K. tubiflora and K. pinnata (Crassulaceae) were isolated and
could be identified as p-hydroxybenzoic-, protocatechuic-, gallic-, p
-coumaric-and coffeic acid. By measuring length of stems and primary r
ests of Kalanchoe-daughter plants the intra-and interspecific inhibito
ry activities of authentic compounds could be demonstrated.
