나물자원의 수경재배시 양액농도가 생장 및 무기물함량에 미치는 영향을 조사하고자 벌개미취, 원추리 및 질경이를 펄라이트 배지에 추식하여 70일간 재배 한 후 생장정도와 무기물 함량을 분석하였다. 벌개미취와 원추리의 초장, 줄기직경, 잎의 수, 신선중 및 건물중은 1.5배액 처리구에서 확연하게 우수한 결과를 나타내었다. 질경이의 지상부와 지하부 생체중 및 건물중 등은 양액의 농도가 0.2재액에서 1.5배액으로 증가할수록 증가한 반면, 엽수와 근장은 0.5배액과 표준농도에서 가장 높은 것으로 나타났다. Ca Mg 및 Na 함유량은 벌개미취의 경우 1.5배액에서, 원추리와 질경이는 0.25배액에서 가장 많았다. K 함량은 벌개미취와 원추리는 0.5배액에서, 질경이는 1.5배액에서 가장 많았다. P2O5는 나물종류 및 양액의 농도에 따른 차이가 거의 없었다.

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°C). However, whole length, hypocotyl length, and sprout yield were highly increased at 23°C compared to 20 and 25°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°C than at 20 and 25°C, while antioxidant properties of PI343278 and PI343283 were decreased in a temperaturedependent 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 purpose of this study was to establish the optimal growth temperature and to select genetic resources for production of cowpea sprouts. Seowon was treated between 15°C and 30°C at intervals of 3°C to investigate growth temperature. Twelve resources, including Seowon, IT154149, IT154153, Tvu7426, and Tvu7778, were used for cultivating sprouts at a temperature of 27°C. The yield ratio of cowpea sprouts was highest at 27°C (657%), and was reduced when growth temperature was decreased. The hard seed rate was lower when the growth temperature was increased. Vitamin C content was highest at 24°C (2.85 mg/g), ranged between 2.15 and 2.29 mg/g at other growth temperatures, and increased with the length of the growth period. The inorganic component content of cowpea sprouts did not vary based on growth temperature, while the amino acid content increased with increasing growth temperature between 15°C and 24°C, and then subsequently decreased as growth temperature rose from 24°C to 30°C. IT154153 had the highest yield ratio of cowpea sprouts per genetic resource (647%), followed by Seowon (615%), and Tvu7426 (608%). Genetic resources with a higher yield ratio had smaller seeds, a thinner seed coat, and superior germinability. The inorganic components found at highest concentrations in the cowpea sprouts were potassium, magnesium, calcium, sodium, iron, molybdenum, and zinc (in that order). In comparison to raw seeds, the protein, calcium, zinc, molybdenum, and iron content in the cowpea sprouts was higher, while the content of aluminum and boron was lower.

The sprout characteristics for 783 sprout soybean lines screened by pure line selection method were evaluated. Those 　developed lines were originally collected on farmers fields all around the country. Some of the lines showed higher yield rateof soybean
