Abstract: | The distribution of has been examined in the leaves of plants from five diploid and 12 tetraploid populations of Gibasis schiedeana. Five different chromatographic patterns were found; one occurs only in a single population of diploid plants, two were found in seven populations of tetraploids and the other two in the remaining plants from both diploid and tetraploid populations. Flavonoids were also investigated in three different types of artificially produced triploids. The effects of the changes in ploidy, which are accompanied by Robertsonian fusion and variation in the number of B chromosomes as contributory factors in the observed differences in flavonoid patterns are discussed. |
