Abstract

An investigation was conducted to ascertain the basic information on characteristics of embryonic tissue development among Korean Ginseng, American ginseng, F₁hybrids and BClI(F I pollen back cross to BC₁= Korean Ginseng) seeds. The specific activities oflipoxygenase (LOX) and the protein assays were made during the above embrygrowth 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℃ for 60 days the ratios of embryo/endosperms in P.g., P.q or F₁were about 90%. The ratio was in BC₁F₁, 79.2% during the same period. The ratios of embryo/endosperms of seeds of P.g. or P.q. germinated at 5℃ showed rather higher values as compared to that at 25℃ LOX specific activity the highest in the F₁and decreased in the order of P.g., P.q., and BC₁F₁. 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.
