Abstract:
Morphological and histological characteristies of the root (Banlamgon ) and leat (Daqiingye ) of lsatis indigotica Fort. derived from the autoteraploid (2n = 28) and its parent diploid (2n = 14 ) were compared macroscopically and microscopically. Results showed that expression of poly ploidy giantism resulting from chromosome duplication were evident not only among organs but also among tissues of the same organ. Leaves of the tetraploid contained 1 .79~3.11?g/mg more indigo than the diploid near the harvest time.Inerease of indirubin was also obvious.polysaccharide in the leave showed no much difference but that in the root was doubled and total amino acid was increased by 4.8%.
