Thirty-eight Pea (Pisum sativum L.) genotypes were screened to identify varieties to be suitable for sprout. Based on seed yield and sprout qualities such as whole length and sprout yield, five genotypes (PI269803, PI343278, PI343283, PI343300 and PI 343307) were primarily selected as candidates for pea sprouts. In order to determine optimal cultivation condition for pea sprouting, growth characteristics were investigated according to the change of germination temperature and days for sprouting. Whole length and hypocotyl length were observed to increase as a time dependent manner at each tested temperature (20, 23, and $25^{\circ}C$). However, whole length, hypocotyl length, and sprout yield were highly increased at $23^{\circ}C$ compared to 20 and $25^{\circ}C$. Especially, PI269803 and PI343300 showed higher sprout yield than the others. In addition, the effect of the change of germination temperature on antioxidant properties was estimated by measuring total phenolic content (TPC) and free radical scavenging activity (DPPH and ABST activity). TPC and DPPH/ABST activities of PI269803 and PI343300 were higher at $23^{\circ}C$ than at 20 and $25^{\circ}C$, while antioxidant properties of PI343278 and PI343283 were decreased in a temperature-dependent manner. The results show a high degree of correlation between TPC and antioxidant activities and suggest that the temperature change for pea sprouting could be responsible for antioxidant properties. Taken together, these results provide optimal cultivation conditions for pea sprouting and suggest that PI269803 and PI343300 with high sprout yield and antioxidant properties could be used for pea sprouts.

The genus Sedum comprises about 400 taxa with worldwide distribution, and about 20 taxa of the genus Phedimus distributed from Asia to Europe. According to some taxonomists, Phedimus and Sedum are two separate genera of the family Crassulaceae; however, in Korea Phedimus has been treated as a subgenus Aizoon within the genus Sedum. This ambiguous taxonomic treatment of the genus Phedimus needs further confirmation. In the study, we investigated morphological characteristics such as the whole plant height, leaf morphology, and seed coat features of these two genera. We believe that these characters are very important to distinguish Phedimus and Sedum. The result indicated that the seed surface pattern was the most useful diagnostic character. The Sedum had a hexagonal pattern with a single nipple protrusion, whereas the Phedimus had a rectangular pattern with papilla on both ends. The results of this study strongly support the separation of Phedimus from Sedum and thus Phedimus need to be treated as an independent genus.

The morphology and somatic chromosome numbers of Korean Parasenecio were investigated to estimate their taxonomic values. Some morphological characters, such as the length of whole plants, the numbers of cauline leaves, the shapes of leaf and petioles, the numbers of involucral bracts, floret numbers per head, presence of trichomes on the style, ratio between wide part and narrow part of floret and the size of achene were found to be a good characters for delimiting each taxa. Based upon these characters, six taxa, Parasenecio auriculala var. auriculata, P. auriculata var. kamtschatica, P. hastata subsp. orientalis, P. koraiensis, P. firmus, P. pseudotaimingasa, were recognized about their distribution in Korea, but 2 taxa, P. adenostyloides, P. auriculata var. matsumurana, were needed to be studied their taxonomic position and distribution in Korea. The somatic chromosome numbers of six taxa, P. adenostyloides, P. auriculata, P. auriculata var. kamtschatica, P. hastata subsp. orientalis, P. firmus, P. pseudotaimingasa were 2n=60 and those of P. firmus and P. pseudotaimingasa were reported first in this study.

Pimpinella brachycarpa, a summer-green perennial herb, is narrowly distributed in the moist forest floors. We investigated environmental characteristics and growth patterns of Pimpinella brachycarpa depending on the microenvironment in Mt. Jeombong located in the central part of Korea. P. brachycarpa populations were located at an altitude of 978~1016 m and the average atmospheric humidity hovered at 80 percent. Also, it was found that the soil moisture content was remarkably high, 26.7%, in the populations; organic matter 11.1~11.7%; the nitrate nitrogen 0.60%; available phosphorus 19.5~39.0 ppm; CEC $20.8{\sim}21.3cmolckg^{-1}$; soil pH 4.7~4.8 respectively. In case of growth pattern, the shoot length of individuals under the improved light condition in the sunny forest was statistically longer than in the dense forest. Therefore, we presumed that high humidity and ample soil moisture are abiotic factors of the growth of P. brachycarpa and that the amount of light affects the relative growth rate of individuals.

산채는 사람에 의하여 개량 육성되어 논밭에서 재배하고 있는 농작물과 달리 자연 그대로 산야에서 자생하는 식물 중 식용으로 가능한 것을 말한다. 산채류의 이용형태별 생산가능시기는 3~5월의 생채 생산과 6~7월의 건채 생산으로 소비자의 기호에 부합하는 신선 생채의 소비한계는 제한되어 있기 때문에 재배유형별 생채 수량검정을 통해 수확시기 연장 및 재배품목을 다양화 시킬 필요 있다. 따라서 본 시험은 재배가능한 산채류를 수집하고 기능성 분류를 통한 꾸러미 산채 조합을 구성하였고 조합된 산채류 들에 대한 생산성 검정을 위해 해발 500m의 전라북도 농업기술원 허브산채시험장에서 2018년 5월 말 갯기름나물 등 15 종을 정식하여 각 작물의 생육특성, 수확한계기 등을 조사하였다. 기능성 분류 결과 항당뇨, 항고지혈증, 항비만, 항혈전, 항염증 총 5가지 조합을 구성하였다. 산채류별 광합성특성 조사결과 돌단풍, 개미취, 섬쑥부쟁이, 질경이, 갯기름나물, 참취의 적정광량은 600~800 μmole/m²/s이였고 눈개승마, 어수리, 참당귀는 400~500 μmole/m²/s, 곤달비, 곰취, 단풍취는 200~300 μmole/m²/s이였다. 기능성 꾸러미 산채류 지상부 생육특성 결과 갯기름나물, 질경이, 참취, 곤달비 섬쑥부쟁이 등이 생육이 우수하였다. 수량성은 섬쑥부쟁이 1,694.6kg/10a로 가장 높았으며, 갯기름나물 1,673.4kg/10a, 참취 1,521.3kg/10a, 질경이 1,398.3kg/10a, 곤달비 1,300.6kg/10a 등이 높았다. 반면 돌단풍 111.8kg/10a, 단풍취 69.5kg/10a, 우산나물 25.4kg/10a로 아주 낮은 수량성을 보였다. 산채류 출현기는 산마늘이 2월 7일로 가장 빨랐으며 대부분 산채류들이 2월 11일에서 2월 25일에 출현하였고 단풍취, 우산나물이 3월 6일로 늦은 출현기를 보였다. 기능성 꾸러미 생채 수확가능 시기는 3월 상순부터 6월 하순까지 가능하였고 수확기간은 섬쑥부쟁이 117일, 두메부추 109일, 어수리 102일, 참당귀 102일로 길었고 돌단풍, 산마늘, 눈개승마, 우산나물은 생채 수확가능 시기가 짧았다. 건나물 수확기간은 돌단풍, 눈개승마는 3월부터 6월까지 가능하였고, 대부분의 산채류들이 5월부터 10월까지고 산마늘과 우산나물은 건나물을 생산할 수 없었다. 산채류 기능성 꾸러미별 생채 조합 가능 시기는 항당뇨는 3월 중하순, 항고지혈증은 3월 중순, 항비만은 3월 하순, 항혈전 3월 하순, 항염증은 3월 중하순으로 조사되었다.

Traditionally mungbean(Vigna radiata L.) sprouts has been eaten soon after washing. The study was carried out to measure the effect of washing before packaging on morphological characters and color of mungbean sprouts. The seeds of cv. Zhong Lu 1 were soaked in 50 ppm BA solution immediately before 4 hour aeration and then cultured for 6 days. The sprouts were washed immediately before packaged with PE envelops or not, and then stored 5 days at $8^{\circ}C$. Their morphological characters, fresh and dry weights, and colors were measured everyday. Compared to washed, nonwashed sprouts had more lateral roots although the two sprouts did nearly same in hypocotyl and root lengths, hypocotyl diameter, fresh and dry weights. Non-washed sprouts, moreover, showed higher brightness in hypocotyl and root and cutting resistance in hypocotyl although there were not significant differences in color a and b, meaning that the latter ones were more rapidly changed during their storage. In non-washed sprouts, number of lateral roots, hypocotyl length and diameter, total fresh and dry weights were nearly same up to 3 days and afterward were declined. Brightness and color b of hypocotyl were decreased with increased storage period although cutting resistance of hypocotyl was since 3 days after storage.
