Abstract
An investigation was conducted to ascertain the basic information on characteristics of embryonic tissue development among Korean Ginseng, American ginseng, $F_{1}$ hybrids and $BC_{1}F_{1}(F_{1}$ pollen back cross to $BC_{1}=Korean\;Ginseng)seeds$. The specific activities of lipoxygenase (LOX) and the protein assays were made during the above embry­onic growth period at 5 or 25 degree C. The results are summarized as follows: The fresh weights(mg) of germinating seeds were significantly different among species. Ginseng seeds were stratified at $5^{\circ}C\;for\;60\;days$ the ratios of embryo/endosperms in $P.g.,\;P.q\;or\;F_{1}\;were\;about\;90{\%}$. The ratio was in $BC_{1}F_{1},\;79.2{\%}$ during the same period. The ratios of embryo/endosperms of seeds of P.g. or P.q. germinated at $5^{\circ}C$ showed rather higher values as compared to that at $25^{\circ}C$ LOX specific activity the highest in the $F_{1}$ and decreased in the order of P.g., P.q., and $BC_{1}F_{1}$. The highest LOX specific activity was shown at 80 days after sowing, followed by 70 days sowing, the least LOX activity was shown at 60 days.
