This study was carried out to investigate the distribution of native Asparagus cochinchinensis and ecological characteristic in South Korea. Natural vegetative areas were investigated at 5 areas; Taean, Buan, Geoje, Namhae and Jindo. In this study, the 5m×5m quadrat was established for recording coverage and appearance species by phytosociological method. The flora of the studied area in native habitats were listed as 130 species. The native habitats was classified into Pinus thunbergii community and typical community. Two communities were located in a coastal cliff and have been destroyed. Therefore Asparagus cochinchinensis native habitats must be protected by regulation. In the studied sites, soil pH, organic matter, nitrogen, available phosphorus, exchangeable K, exchangeable Ca, exchangeable Mg and cation exchange capacity were ranged from 5.1~5.7%, 1.77~3.59%, 0.19~0.54%, 5.4~18.7 (mg/kg), 0.24~0.48 (cmol+/kg) 0.76~2.83 (cmol+/kg), 3.11~6.22 (cmol+/kg) and 8.7~24.5(cmol+/kg), respectively.

콩 재래종과 야생종 자원의 엽 형질간의 관계를 분석하여 콩의 엽형 조사를 계량화할 수 있는 기준을 제시함으로써 콩의 초형개량과 재배법 개선을 위하여 필요한 기초자료를 제공하고자 충북대학교 농업생명환경대학 두류유전자원관리실에서 분양받은 콩 재배종 94개와 야생종 91개의 엽형질을 조사한 결과는 다음과 같다. 1. 재배종과 야생종의 엽장은 각각 12.3pm1.25 cm(8.7~15.3 cm)과 평균 6.6pm1.35 cm(3.7~11.3 cm), 엽폭은 각

Genetic diversity plays a great role in the survival and adaptability of a species under changable environment. Korea is known as original region of cultivated soybean species with high genetic diversity of wild and cultivated soybean lines. We have collected many semi-wild soybean lines, however, the information about the genetic diversity of these lines is limited. And also the phylogenetic relationship and genetic distance among the semi-wild, typical wild types (Glycine soja Sied. & Zucc.), and cultivated soybean(Glycine max (L.) Merr.) have been controversial. This study was carried out to analyze the diversity of the three groups, and to verify their genetic variation and relationships among them. The diversity indexes of typical wild, semi-wild, and cultivated soybean accessions were 0.854, 0.677, and 0.528, respectively. According to the cluster analysis for the genetic relationships, 58 accessions were defined into three genetic groups. Cluster I consisted of 20 cultivated soybean accessions and three semi-wild soybean lines. Cluster II contained 13 semi-wild soybean lines and one typical wild soybean line. Cluster II included 21 typical wild soybean lines and one semi-wild soybean line. Genetic distance between cultivated and semi-wild soybean, typical wild and semi-wild, and cultivated and typical wild were 0.525 0.761 and 0.810, respectively. The relationship between semi-wild soybean was much closer to the cultivated soybean the to the wild soybean

천문동 (Asparagus cochinchinesis (Lour.) Merr.)의 기내생장과 증식의 가능성을 검토하기 위하여 신초의 유기, 생장 및 발근에 적합한 배지, 식물생장조절제, 배양온도를 검정한 결과를 요약하면 다음과 같다. MS 기본배지에 3.0 mg/l BA 처리시 신초의 유기 및 생장이 가장 양호하였으며 MS 기본배지에 0.5 mg/l IBA 처리가 발근에 가장 효과적이었고 기내배양 온도는 23~25℃가 적합하였다.

Number of nodes and branches are yield component characters whose expression are highly related with many other traits. In this study, a population derived from the cross of ‘Keunolkong’ and ‘Shinpaldalkong’ was evaluated with SSR markers to identify QTLs

This study was carried out to investigate the best explant source and combination of media and growth regulators for the regeneration of multiple shoots in soybean (Glycine max. L. Merr.) cv. ‘Iksannamulkong’. Multiple shoots could well be directly induce

한약재 및 식품으로의 개발가능성이 높지만 현재 멸종위험에까지 처해있는 천문동의 체계적 보호 및 보존을 위하여 자생지 분포특성조사와 유전자원을 수집한 결과는 다음과 같다. 1. 서해안(충남 이남)과 남해안, 동해안(경북 이남)의 45개 지역을 중심으로 유전자원의 분포특성 조사를 실시하였으며 자생이 확인된 26지역으로부터 천문동 자생종을 수집하였다. 2. 자생지분포 조사 결과 섬을 제외한 육지부 천문동 자생지는 북위 36˚15' (충남 보령군 남포면 월전리 죽도) 이남의 서해안으로부터 동경 128˚02' (경남 사천시 실안동 강포) 이서의 남해안이었다. 3. 천문동은 해안선에 주로 분포하고, 자생지 주요 식생은 소나무가 우점 하였다. 4.자생지 천문동의 생육상황은 햇볕의 투과정도가 좋을수록 지하부 생장량이 많았다.
