The origin of cultivated Prunus yedoensis Matsumura has been controvertial among botanists. This plant has been reported grown wild in Mt. Hanla. During the crossing experiment on the P. yedoensis and its putative parent performed from April 7 to 19 in Mt. Hanla, the writer studied morphological and physiological characteristics of various species of Prunus and assumed that the wild P. yedoensis may be a hybrid between P. subhirtella var. pendula form. ascendens and P. donarium.

We determined the nationwide seroprevalence of hepatitis E virus (HEV) infection in the wild boar population in Korea. Enzyme-linked immunosorbent assay (ELISA) results showed that 42% of the 528 wild boars that were hunted between 2013 and 2014 were anti-HEV antibody positive. Furthermore, all Korean provinces showed an HEV seroprevalence between 9.8% and 51.1%, suggesting that wild boar HEV infection occurs throughout the country. Importantly, infected wild boar could act as a potential reservoir for HEV and could aid transmission to other animals and humans.

The plants medicinal resouces of middle area of Korea were investigated 10 times from May 1, 1993 to November 30. 1994. In order to analyze the vegetation of middle wild plants structure and distribu-tion. Medical wiId plants of middle southern area consisted of 100 familis, 380 specis in all. Theresources of important herb drugs were Polypodiaceae, Graminae, Liliaceae, Polygonaceae,Ranunculaceae, Brassicaceae, Rosaceae, Fabaceae, Apiaceae, Labiatae, Solanaceae, Scrophulariaceae,Campanulaceae, Compositae. The herb drugs were comparatively more than in other mountains in ourcountry.

Wild Korean ginseng has been recognized as highly precious medicine since ancient times. Nowadays, the population of wild ginseng in the forest of Korean peninsula is very rare due to indiscreet harvest. In this work, we investigated the plant regeneration via somatic embryogenesis from embryogenic callus of old wild ginseng (more than 50 years-old) and compared the features of plants regenerated from 5-years old and 50 years-old ginseng. Induction of embryogenic callus from adventitious roots of 50 year-old wild ginseng required 83 weeks of culture, but only 10 weeks were sufficient for 5 year-old ginseng. Height and width of plants derived from the old wild ginseng was smaller and slender compared to the plantlets derived from 5 year-old ginseng. Total chlorophyll contents was 2-6 time lower in plantlets regenerated from 50 year-old wild ginseng than those from 5 year-old ginseng, but anthocyanin content was higher in 50 year-old ginseng. Our results revealed that plants regenerated from old wild ginseng have different morphological and physiological characters probably due to age-dependent phenomenon.

Wild soybean plants(Glycine ussuriensis) collected from Korea(47 strains) and abroad(41 strains) were grown under field condition and classified according to the growth habit. Seeds were analyzed for protein content. The results were as follows: 1. Wild soybean plants were classified into three groups each by seed size, growth habit of stem, leaf size and flowering time. 2. Seed protein was higher in the strains with large leaves, tendril, stem or late flowering. 3. Glycine gracilis, supposed to be the intermediate species between cultivated and wild soybean(according to the stem growth habit, straight or semitendril, and seed size) was medium in protein content of seeds. 4. The average protein content of Glycine ussuriensis, 43.2%, was highest in comparison with those of others such as G. gracilis, 37.5%, or G. max, 36.2%. 5. One hundred seed weight of Amphicarpaea trisperm, similar to the wild soybean, was almost same as Glycine ussuriensis, but protein content of this species was lower than wild soybeans.

In May 2020, we surveyed disease occurrence on vegetables grown in Seosan area, Korea. During the disease survey, white rot symptoms were observed in Korean wild chive (Allium monanthum) plants growing in fields. The symptoms occurred mainly in the seed bulb-producing fields of the crop. The above ground parts of the diseased plants displayed premature yellowing and dying of older leaves and stunting of the plants. The bulbs and roots of the diseased plants turned black and rotted. The disease occurred in a range of 1-60% in four of the eight fields surveyed. Three isolates of Sclerotium sp. were obtained from the bulb lesions of diseased plants. All isolates were identified as Stromatinia cepivora based on the morphological characteristics and phylogenetic analysis. Pathogenicity of the isolates on Korean wild chive was confirmed by artificial inoculation test. The lesions induced by the inoculation test were similar to those observed in the investigated fields. This is the first report of S. cepivora causing white rot in Korean wild chive.

Mitochondrial DNA restriction fragment length polymorphisms are convenient markers for identifying cytoplasmic variation among plants. We have collected 212 wild soybeans (Glycine soja Sieb. et Zucc) from all over Korea, and classified mitochondrial genome types based on hybridization patterns in DNA gel-blot analyses using two mitochondrial DNA clones, cox2 and atp6, as probes. Korean wild soybean was classified with eight-mtDNA types, and some of the mtDNAs showed geographical clines among the regions. The diversity index of the mtDNA was much higher in the western and southern regions than in the eastern and northern regions of Korea, respectively. Dissemination and distributive characteristics of wild soybeans in Korea were discussed.

Wild vegetables, such as Cirsium setidens, and Aster scaber, are commonly distributed as dried materials because the wild vegetables lose their freshness quickly after harvest and distribution. Dried wild vegetables require rehydration to use as a food ingredient, and the quality of rehydrated wild vegetables is affected by pre-drying and drying methods. Here, we introduce the newly developed pre-drying and drying method, termed "micro oil sprayed thermal air (MOTA) technique". The three wild vegetables processed by the MOTA technique showed improved rehydration rate and reduced time to achieve maximum rehydration rate. Color characteristics were also improved in C. setidens. These results indicate that the MOTA technique improves the overall quality of rehydrated wild vegetables. It is expected that our findings could enhance the marketability of dried wild vegetables by improving overall quality and reducing preparation time.

American ginseng (Panax quinquefolium) is herbaceous perennial plants indigenous to North American forests. This is highly valued as medicinal herbs with a long history of collection from wild populations since 1716. Wild American ginseng distributed from Quebec in Canada to northern Florida in USA. A heavy concentration is found in the Appalachian mountains, although wild American ginseng is considered endangered. The price paid for field cultivated ginseng has dropped dramatically in the past 10 years, while the price for wild or woods cultivated ginseng has rised significantly. The price curve for ginseng resembles a roller coaster, reflecting not only supply and demand but many other factors. This information will be useful to understand American ginseng compared to Korean ginseng.

담배가루이 성충에 대한 식물정유의 기피효과를 조사하기 위하여, 20종의 식물정유를 대상으로 담배가루이 성충의 기피반응을 검정한 결과, mint 오일만이 $5{\mu}{\ell}$의 약량처리에서 90% 이상의 높은 기피효과를 나타내었다. 2, 1, 0.5, $0.1{\mu}{\ell}$ 약량처리에서는 77.8~65.7%로 농도의존적으로 유의성이 나타났다. Wild mint 오일을 분석하고 생물검정을 수행한 결과, GC/MS 분석으로 wild mint oil의 주요 구성성분이 menthol(56.5%), menthone(29.0%), menthyl acetate(14.5%)로 밝혀졌으며, 기피활성을 보인 주요구성성분은 원래 오일에 함유되어 있는 비율로 $10{\mu}{\ell}$ 오일을 처리하였을 때 menthol과 menthone이 각각 77.8과 75.8%의 기피효과를 나타내었으며, menthyl acctate는 유의성이 없었다. 주요 구성성분을 혼합하여 잠정한 결과, 단독검정시와 비교하여 기피효과가 더 높게 나타났다.
