Background: The objective of the present study was to investigate the effect of storage conditions on the growth of Saururus chinensis (Lour.) Baill. rootstock.Methods and Results:Rootstocks of S. chinensis were stored in either soil or vermiculite that had been treated with a control treatment, diluted wood vinegar (50 or 100-fold), DF-100 (50-fold), or 1-naphthylacetamide and at 5°C or 15°C. After 8 weeks, the stored roots were planted in the field, and both plant height and leaf number were observed after transplantation. The greatest number of leaves (5.60 ± 0.80) was produced by roots that had been stored in soil treated with 100 fold dilution of wood vinegar and at 5°C. Meanwhile the maximum plant height (6.92 ± 0.78 ㎝) at 30 d after transplanting was observed for rootstocks that had been stored in soil treated with the 100 fold dilution of wood vinegar and at 15°C, whereas the maximum plant height at 60 d after transplanting (26.46 ± 0.71㎝) was observed for rootstocks that had been stored in soil treated with the 100-fold dilution of wood vinegar and at 5°C. Therefore, the storage of rootstocks in soil treated with the 100-fold dilution of wood vinegar and at temperatures at or below 5°C was most effective, and it can be used to prevent the decay of roots during the postharvest management of S. chinensis rootstocks.Conclusions:The results of the present study indicate that, among the parameters examined, the storage of roots in soil that had been treated with the 100-foil dilution of wood vinegar is the most effective method for improving the growth of S. chinensis.

This research was performed to develop seminal propagation method of Saururus chinensis (Lour.) Baill. by conducting a rigorous germination study. Well-selected seeds were dry-stored at 4 ± 1.0℃ during the experiment. To study dormancy type, non-stored seeds were analyzed by embryo observation, germination test and detecting for any difficulties in seed coat to absorb moisture. Then to improve germination, seeds were submerged for 24 hours in a solution of varying concentrations containing one of plant growth regulators and minerals. According to research, fleshly matured seeds had an undifferentiated embryo and had a low germination rate below 5%. In addition, water submersion led to moisture absorption, embryo in the seeds grew and germinated so it was deemed morphophysiological dormant seeds. Percent germination (PG) and germination energy (GE) was greatly improved by soaking in plant growth regulators and minerals for 24 hours. Especially, 500 ㎎/L GA3 treatment resulted in the highest GE as 46.1%. KNO3 meaningfully improved PG (54.3∼57.7%) at 10∼20 mM but effect of minerals on germination acceleration as GE were negatively impacted in all concentrations.

홍삼(panax ginseng C.A. Meyer) 추출물 단독의 항산화 활성과 홍삼추출물에 삼백초(Saururus chinensis(Lour.) Baill.)와 복분자(Rubus coreanus Miq.) 추출물을 농도별로 보충 급여 하였을 때 나타나는 상승효과를 알아보기 위하여 Sprague Dawley rat에 이들 추출물을 8주간 섭취시킨 후 희생시켜 간장 cytosol중의 superoxide dismutase, catalase, glutathione peroxidase, GST 등의 항상화 효소계 활성을 측정하였다. 그 결과, 홍삼급여군의 superoxide dismutase, catalase, glutathione peroxidase의 효소활성이 대조군에 비해 농도 의존적으로 높았다. 특히 홍삼 단독보다는 삼백초와 복분자를 보충급여시 상승효과가 높았으며 급여기간이 길수록 그 효과가 높았다.
