This study was carried out to compare the root yields, root characters, saponin and ginsenosides contents of 6-year-old p. ginseng and p. quinquefolium. These two ginseng species showed difference in the diameter and ten비h of mainroot. The main root length or p. quinquefolium was shorter than that of p. ginseng, whereas Jakyung-jong and Hwangsook-jong of P. ginseng showed similar root length. Proximate composition were similar between the two species, however, crude fibercontent was significantly higher in main and lateral root of Jakyung-jong and Hwang sook-jong of P ginseng than P quinquefolium. In regard to mineral contents of root, P ginseng contained more Ca and Mn and less Fe and Al than P. quinquefolium. P. quinquefolium contained more of Rbl and Rd of protopanaxadiol saponin, and less or Re, $Rg_1$ and $Rg_2$ of protopanaxatriol saponin than P ginseng. However, no Rf was detected in the p. quinquefolium. Key words Panax ginseng, Panax quinquefolium, ginseng character, ginsenoside.

The content and composition of saponin compounds of Panax species were analyzed according to their species, region and processing type of red and white ginseng. The species employed were Korean-, Chinese-, Japanese red ginsengs, and Korean white ginseng of Panax ginseng, American- and Canadian ginsengs of Panax quinquefolium, and Panax notoinseng. Twelve main saponin components in the ginseng were identified and quantified using TLC and HPLC. All three species had remarkably different content and composition. However, within each species they were similar. Twelve major ginsenosides were determined in P. ginseng, eight in p. quinquefolium, and six in P. notoginseng. Of the components of P ginseng Rf, $Rh_1$, $Rh_2$ and Ra were not detected in P quinquefolium, and $Rb_2$, Rc, Rf, $Rh_2$, Ra and Ro not detected in P. notoinseam. Crude saponin content and protopanaxadiol/protopanaxatriol saponin ratio were compared. They were 4.81~5.24% and 1.27~ 1.45 in p. ginsengs, 7.01~7.25% and 2.12~ 2.15 in p. quinquefolium, 9.80% and 0.99 in P. notoineng. The prosapogenin and sapogenin content were different among the Panax species.

Chemical components of Panax (P) species were compared. p. species used were Korean white ginseng, Korean, Chinese and Japanese red ginseng (P ginseng), American and Canadian ginseng (P. quinquefolium) , and sanchl ginseng (P. notoginseng). No significant difference in the proximate contents was observed among P. species. Ash, crude lipld and total sugar contents in root of P. notoginseng were found to be relatively lower than those of P. ginseng and P. quinquefolium, but the contents of crude protein and crude fiber were similar among those ginsengs. Mineral nutrient con tents showed a little difference among ginseng species. Total nitrogen contents were slightly higher in P. ginseng than P. quinquefolium and P. notoginseng and Fe and Cu were lower in Chinese and Japanese red ginsengs. Kinds and compositions of amino acids were similar but contents of amino acids were different among ginseng species. Total amino acid contents were 76.3∼83.9 mg/g in P. ginseng 53.8∼60.4 mg/g in p. quinquefolium and 54.9 mg/g in P notoginseng. Free sugar contents were lower in P. notoginseng than P. ginseng or P. quinquefolium. Sucrose accounted for 90∼92% of total free sugar contents with relatively high content in white ginsengs, while sucrose and maltose were 32-36% and 55∼60%, respectively, in red ginseng.

This work was carried out to establish adventitious root culture system in three Panax species (wild-grown P. ginseng, P. quinquefolium, and P. japonicum) to analyze their ginsenoside productivity. Adventitious roots were induced directly from segments of seedlings after cultured on MS(Murashige andSkoog 1962) solid medium containing 3.0 mg/l IBA. Omission of $NH_4NO_3$ from the medium greatly enhanced both the frequency of adventitious root formation and number of roots per explants in all the three Panax species. However, elongation of post-induced adventitious roots was enhanced on medium with $NH_4NO_3$. Two-step culture protocol: $NH_4NO_3$-free medium for first two weeks of culture, followed by $NH_4NO_3$ containing medium for further 4 weeks, greatly enhanced the fresh weight increase of adventitious roots in all the three ginseng species. The fresh weight of adventitious roots was high in P. quinquefolium and low in P. ginseng, followed by P. japonioum regardless of the composition of medium. Pattern and content of ginsenosides in adventitious roots differed among the three Panax species. Total ginsenoside content of adventitious roots in P. quinquefolium, P. ginseng, and p. japonicum was 8.03, 15.7 and 1.2 mg/g dry weight, respectively. Among the three speices, adventitious roots in P. quinquefolium produced hig-hamount of ginsenosides. The pattern of ginsenoside fractions between P. ginseng and P. quinquefolium was similar but the amount of ginsenoside differed between the two, While, in P japonicum, total ginsenoside content was very low and some ginsenosides such as ginsenoside Rb2 and Rf were not detected. Conclusively, we demonstrate that same culture condition was required for induction and elongation of adventitious roots of three ginseng species but growth of adventitious roots and their ginsenoside production were different among them.

This study was carried out to clarify the cause of incompatibility in interspecific hybrid plant between Panax ginseng and p. quinquefolium. The floral structure of F,(p.g. x p.q.) hybrid was normal because the redundant anther was 0.2 mm longer than pistil in Fl hybrid and the size and structure of redundant carpel in F, hybrid were similar to P. ginseng and p. quiquefolium Pollens of $F_1$ hybrid did not germinate on stigma of P-quinquefolium but germinated well on stigma of P. ginseng. Pollen tube was able to penetrate styles completely and seed harvest rate was 16.8% in field. However on stigma of $F_1$ hybrid, Pollen did not germinate when P. ginseng was used as male Parent. In addition, the growth of pollen tube was halted on style and seed was not set when P qlfinquefoEi2a was used as male Parent. These suggest that the inhibitor of pollen germination present on stigma caused $F_1$ hybrid sterility. It took 5 hours for pollen grains to germinate, 12 hours to arrive at in trance of ovule, 16 hours to penetrate micropyles in Panax ginseng.

Systematic electrophoretic analysis of alcohol-soluble proteins and salt-soluble proteins of 247 Panax ginseng (P.g) and Panax quinquefolium (P.q) germplasms seed was carried out on an improved lactate-polyacrylamide gel electrophoresis, a method with high resolving power, good reproducibility and stability. The electrophoregrams of proteins, according to their migration rate, were classified into four groups such as ${\alpha}$, ${\beta}$, ${\gamma}$ and $\omega$ for the alcohol-soluble proteins and three such as I, II and III for the salt-soluble ones. Panax ginseng or Panax quinquefolium had their own unique band pattern distinguishable from each other, regarding as their specific "fingerprint". In this study, 3 of 168 (1.8%) P.g germplasms and 1 of 79 (1.3%) P.q germplasms had their own unique band pattern, showing that P.g and P.q germplasms have poor genetic diversity in species. The band patterns of dry seed and stratified seed (embryo rate=60%) were basically the same. The band number of the F, hybrid of p.gx p.q was exactly equivalent to the number of the common bands plus the specific bands of the two parents, indicating that the difference of band patterns was a genetic trait con- trolled by the nuclear genes. The electrophoregram of F1 of P.g x P.q could be predicted by that of the two parents and the band pattern of the F1 hybrids could be demnonstrated by that of the mixed seed extract from the two parents.
