The graminicides fluazifop-p-butyl and sethoxydim effectively controlled annual grass weeds in 1,2 and year old ginseng crops during a 2 year study. Ginseng plants in the graminicide treated plots showed an early senescence of the shoots ; and at harvest the average root weight (g/root) and yield (kg/m) were slightly lower in these plants than in the untreated check plots. Roots of the graminicide treated plots remained viable to regenerate shoots. The greenhouse study indicated that shoot growth and seed development in ginseng plants were more sensitive to the graminicide treatment than the roots.

This experiment was conducted to study whether priming with deep sea water results in enhancement of seed germination and to identify the optimum concentration of the priming solution, and duration of priming using sweet pepper (Cv. California wonder), rice (Cv. Ilpum) and ginseng seed. Sweet pepper and rice seeds were primed with 5 various concentrations (5%, 10%, 15%, 20% and 30%) for deep sea water for 48 hours, 24 hours and 12 hours at $25^{\circ}C$ and ginseng seeds in 5%, 10%, 15%, 20%, 25% and 30%, and 2,4,6, and 8 electrical conductivity (EC) which were made by desalinating deep sea water. Priming in deep sea water (DSW) improved the early and final germination percentage, mean germinal on rate, emergence percentage and root and shoot length, compared with plain water, $KNO_3$ and without priming treatments. In sweet pepper, 24 hours priming with 5 percentage DSW significantly improved the early germination percentage and radical length. It has also improved the mean germination and emergence days and early emergence percentage, compared with $KNO_3$ and control. Whereas, in rice, 48 hours priming with 10 percent DSW significantly improved the early germination percentage, plumule emergence percentage, root length and shoot height. Hence the best seed priming treatment on sweet pepper and Rice are 24 hours with 5 percentage DSW and 48 hours with 10 percentage DSW, respectively, whereas in ginseng, priming with EC4, EC8 and 25% DSW had shown better germination.

Spring sowing of ginseng seeds often results in failure of seedling establishment. Storage condition during winter, sowing time, and seed treatment might effect on germination. Here we tested effects of temperature regimes of seed storage on spring sowing. Dehisced wet or dry ginseng seeds were stored at $2^{\circ}C$, $-2^{\circ}C$, $-3.5^{\circ}C$, or alternating temperature: at $2^{\circ}C$ until December, $-3.5^{\circ}C$ in January, and $2^{\circ}C$ in February, and sowed in March. In overall, emergence rate was dependent on storage temperature, and $-3.5^{\circ}C$ resulted poorest emergence than other conditions. Storage of wet seeds in alternating temperature resulted highest emergence rate. Seed dry also affected on emergence rate, while it was dependent on the storage temperature. In terms of growth, storage at $2^{\circ}C$ as wet seed resulted highest growth, and dried seeds resulted poorer growth than wet seeds. As a modification of alternating temperature, seeds were stored at $2^{\circ}C$ at first, then transferred to $-3.5^{\circ}C$ at Nov 30, Dec 20, and Jan 10, each. When transfer date was delayed, emergence rate was increased. We suggest that seed storage temperature for ginseng should not be decreased below $-2^{\circ}C$, and alternative temperature regime for successful spring sowing could be useful.

Vicilin and legumin, the storage Proteins of seed, were Purified from ginseng (Panax ginseng C.A. Meyer) endosperm cells. They were immunized in rabbits, and antibodies were raised respectively. Using these two antibodies, double immunogold labeling of vicilin and legumin was carried out to determine the gap of synthetic time and the transport pattern of vicilin and legumin in the ginseng endosperm cells. Vicilin and legumin were synthesized at the same time at early embryo developmental stage. They were secreted from the Golgi bodies and accumulated into the small vacuoles. As the endosperm cells developed, vicilin and legumin localized in the small vacuoles were gradually transported toward the large central vacuole where they were stored. Protein bodies were derived from the vacuoles filled with proteins and distributed in the endosperm cells of mature red seed. Protein bodies were various in size from 1 to 8 ${\mu}{\textrm}{m}$ in which vicilin and legumin were mixed each other. The number of small particles labeled on the vicilin was greater than that of large particles labeled on the legumin in the protein bodies indicating that the amount of vicilin is higher than that of legumin in the protein bodies.

Ginseng has been traditionally used in Asia including Korea, for health care and to treat verities of different diseases such as immune disease, liver disease, and cancer. The current study was aim to unveal the most efficient method such heating, prethanol-A and ultrasound, for cured extraction of ginseng with higher antioxidant activity. The current results shows a significant improvement in the inhibition of H₂O₂ by the ultrasound method than the HT and Pre-A method. Thus this inhibition in free redical is possible through the increase in the antioxidant activity. Therefore in this study the CAT, APX and phenolic and flavonoid content was increased in ginseng seed and germinated ginseng sprouts by the US method, while the POD, SOD and GSH activity was increased in HT method. This suggest that the different extraction method in different stage of ginseng growth show a different biochemical and metabolites activation. Thereby the Ultrasound and Heat extraction was a feasible alternative method for extracting interested ingredients from biological materials.

In order to develop a novel system for the discrimination of five ginseng cultivars (Panax ginseng Meyer), single nucleotide polymorphism (SNP) genotyping assays with real-time polymerase chain reaction were conducted. Nucleotide substitution in gDNA library clones of P. ginseng cv. Yunpoong was targeted for the SNP genotyping assay. From these SNP sites, a set of modified SNP specific fluorescence probes (PGP74, PGP110, and PGP130) and novel primer sets have been developed to distinguish among five ginseng cultivars. The combination of the SNP type of the five cultivars, Chungpoong, Yunpoong, Gopoong, Kumpoong, and Sunpoong, was identified as 'ATA', 'GCC', 'GTA', 'GCA', and 'ACC', respectively. This study represents the first report of the identification of ginseng cultivars by fluorescence probes. An SNP genotyping assay using fluorescence probes could prove useful for the identification of ginseng cultivars and ginseng seed management systems and guarantee the purity of ginseng seed.

인삼은 다년생 식물로 종자 번식을 하는데, 수확 시 미성숙한 배(embryo)를 가지고 있어 후숙이 필요하다. 기후변화에 대비하고 안정적인 종자 보급을 위해서는 단기 및 장기간 대량으로 종자를 저장할 수 있는 기술이 필요하다. 본 연구에서는 2개 지역에서 얻은 개갑된 인삼 종자를 수분함량을 달리하여 -3.5℃에 보관하고, 저장 3, 15, 27개월 후에 유근과 지상부 출현을 관찰하여 발아력 검정을 통해 종자 저장성을 조사하였다. 3개월 후, 전반적으로 batch #1보다 batch #2에서 발아율이 높았고, 그리고 수분함량이 35% 이상에서만 발아가 원활하였다. 15개월 후, batch #2에서 수분함량이 45~54%인 부분 건조된 종자들에서 가장 높은 발아율을 보였고, 대부분의 무건조 종자는 부패하며 발아에 실패하였다. 수분함량 25% 이하로 건조된 종자들 역시 유근발아 또는 출아가 불량하였다. 부분 건조 종자들은 토양에서의 발아 및 생육도 우수하였지만, 1년 뒤에는 역시 활력을 유지하지 못하였다. 요약하면, 인삼 종자는 온대성 난저장 종자의 특성을 가지는 것으로 보이며, 부분 건조 조건에서는 종자의 수명을 연장할 수 있어 1년 정도의 단기 저장에 활용할 수 있을 것으로 판단된다.

Background: In Korea, seeds of Panax ginseng C. A. Meyer need to be stored under cold temperature and high humidity condition for months to break physiological dormancy, making storage difficult until spring-sowing. This study was conducted to test the effects of seed storage conditions and seed treatment on the emergence of seedling after spring-sowing in a nursery greenhouse. Methods and Results: After dehiscence, endocarp dried seeds in mild or completely, and wet seeds were stored in $2^{\circ}C$ and $-3.5^{\circ}C$ during winter. Storage at $-3.5^{\circ}C$ resulted in a lower emergence rate (ER) than that at $2^{\circ}C$, and additional cold ($2^{\circ}C$) treatment before or after storage at $-3.5^{\circ}C$ increased the ER. Endocarp dehydration prevented pre-germination at $2^{\circ}C$ storage and increased the ER of seeds stored at $-3.5^{\circ}C$. ER was also dependent on the batch of seeds. However, seed treatments before sowing had only limited effects on ER. Root loss was the main reason for damping-off; prolonged cold storage of seeds increased damping-off, as the detection of pathogens was not high. Conclusions: This study showed that storage conditions such as temperature and moisture content of seeds, affect the ER after spring-sowing and vitality of seedlings, suggesting further attention on seed control for secure seedling stands after spring-sowing.
