  • This study investigated the effects of the steeping condition and salinity stress on the quality properties of germinated black soybean. The absorbed water content increased drastically in six hours with the increase in the steeping time and the temperature. The pH decreased as the steeping temperature increased. A gradual increase in the dissolution of the anthocyanin was observed with the steeping time. The adequate steeping conditions were found to have been six hours at $25^{\circ}C$, which showed the needed absorbed water content within a short time. The germination percentage of the black soybeans decreased with the increase in the NaCl concentration. The pinitol and total phenolics contents showed the highest values under the concentrations of 0.7% and 0.3-0.5% NaCl, respectively. The flavonoid content was highest at the 0.1% NaCl concentration. Consequently, the salinity stress during the germination of the black soybeans enhanced the pinitol content and lowered the blood sugar, which gives it an advantage as a functional food material.

  • This study was conducted to evaluate development of seed pellet technique such as pellet polymer search, the shape formation and hardness, the germination and emergence rate of the pellet seeds for labor-saving and reducing production cost in onion(Allium cepa L.) cultivation. The pellet seeds shape formation was good such as kaolin, clay, ash, and gypsum, and clay was good shape formation but surface of pellet seed was cracked during the drying. PG(pearlite + gypsum) as pellet material and PVA as binder were the best among the material in consideration with shape and hardness together. The hardness of the pellet seeds was affected by polymers, the kinds and concentration of binders, and that degree was large at polymer. The high hardness polymers were gypsum and coal ash, but burned lime was the lowest hardness among the pellet material. The germination(GP) and emergence percentage(EP) of pellet seed with PG in vitro were the highest among the material, and that was 93.6, 91.8%, respectively. The EP of pellet seed with PG at 20, $25^{\circ}C$ were 91.3, 92.0%, respectively, The EP of pellet seed were over the 91%, and those did not show difference with field moisture capacity , and that of 5 and 6mm size seed were the highest as 92%, respectively. and other size seeds showed over 90%, too. The EP of pellet seed with PG was decreasing as increasing the sowing depth, and that of at 10mm sowing depth was the highest as 92.7%. The time to 50% emergence of that under 70% field moisture capacity was 158h, and that was delayed at 20h compare to control seed.

  • In the present study, we investigated changes in the nutritional components of pre- and post-germinated barley seeds and also investigated their immune-enhancing effects such as production of nitric oxide (NO), interleukin (IL)-6, and tumor necrosis factor (TNF)-${\alpha}$ on the RAW 264.7 macrophage cell line. Protein and total sugar contents increased slightly with increase in germination time. The major neutral sugars of germinated balrey seeds were arabinose, glucose, and xylose. Glucose content decreased during germination, whereas arabinose and xylose contents increased during germination. Amino acid contents of barley germinated for 24 and 48 hours increased 1.03-fold and 1.24-fold, respectively, compared to that of pre-germinated barley. Moreover, RAW 264.7 macrophages stimulated with barley germinated for 24 and 48 hours showed higher production of NO, IL-6, and TNF-${\alpha}$ compared to that observed in pre-germinated barley. The results of the present study indicate that germinated barley may have immune-enhancing effects derived from its ability to activate RAW 264.7 macrophages, which play a major role in innate immunity.

  • Lilium lancifolium, which is one of the Korean native lilies, possesses several useful genetic characteristics such as growth vigor, bulbil formation and resistance to Fusarium. Hybridization was performed to insert useful traits of Asiatic hybrid "Dreamland" as the male parent with upward direction and dark brown spotless on the petal into L. lancifolium as the female parent. The rate of pollen germination of L. lancifolium and "Dreamland" were 30% and 60%, respectively. The pollen germination ratio of $F_1$ progenies at flowering date was 25-57%, which is between the parents'pollen germination ratio. The individual flowering time was between 113 days and 131 days after planting. Of 99% of all plants, the leaf shape index was more than five, which means that the leaf shape of $F_1$ plants is more influenced by female than male parent. The flower color was separated into four types. 51.5% of the progenies showed orange and 44.2% showed light orange, respectively. The colors seemed to be highly influenced by female parents. Mixed colors of parents, orange yellow and light yellow orange, were 3.1%, 1.2%, respectively. Flowering directions were segregated by three different ways, upside, side, and downside. Side direction, which is medium type between female and male parent, was 73%. All progenies showed lots of spot on petals except one offspring. The percentage of bulbil formation on leaf axil was 49.4%. Among those, the maximum number of bulbil formation was 25. The mean number of bulbil formation per plant was five.

  • This study was conducted to seek optimum sowing time and pinching height for tender shoots production of moloheiya (Corchorus olitorius L.), which is a subtropical leaf vegetables, under an unheated greenhouse in the south of Korea. Seeds of moloheiya did not germinate at all at $10^{\circ}C$, but germinated well at $18{\sim}30^{\circ}C$ with 95.5~98.5% germination rate. Germination rate was 75.0% at $15^{\circ}C$, but germination speed was very low. The pods of moloheiya sown before April 28 was matured after late-August, but those sown after May 7 was not matured in that year. In tender shoot production and harvest frequency, treatment sown on April 14 was most plentiful among sowing time treatments, and showed marketable yield increase by 14~42% compared to other sowing times. Mean-while, pinching at 100cm high from soil surface was more effective than other heights for increment of branches and tender shoot. All above suggest that it was suitable to sow seed on mid-April and to pinch at 100cm high from soil surface for increment of tender shoots in the south of Korea.

  • This investigation was conducted to determine the effect of the optimum planting date and place for good seed production on growth variation, grain yields, different of variety, infection of seed by fungi, and seed germination and vigor after room storage. Early maturity Korean soybean variety, Keunolkong, and introduced vegetable soybean variety, Fukura-edamame, were planted at field of YAES. and high cool land of Sajapyong in Milyang(altitude, 850m) on May 15 (early), June 15 (mid.), and July 15 (late) in 1991. The emergence and vegetative period gradually increased in the early planting date. The grain yield, seed weight, pod number, healthy grain yield also increased when Keunolkong was planted on early date. The healthy seed rate, Keunolkong increased in the early planting date, whereas that of Fukura also increased in the late planting date. Infection ratio of grain to phomopsis seed decay (Phomopsis spp. ' Diaporthe phaseolorum) in Fukura steadily increased in the early planting date. Infection ratio of grain to purple seed stain (Cercospora kikuchii) generally increased in the mid and late planting date. The seed germination and seedling vigor after room storage from five to six months gradually increased in the late planting date. And seed germination of Fukura rapidly decreased in the early planting date. Therefore, the optimum planting date for good seed production in early maturity vegetable soybean was June 15 in terms of harvesting time avoid a high temprature and humidity.

  • Research was initiated in greenhouse to investigate effects of polymer, calcium, perlite and chitosan on the growth of Kentucky bluegrass (KB). A total of 24 treatment combinations were used in the study. Treatments were made of water-swelling polymer (WSP), calcium, perlite, and chitosan in soil organic amendment (SOA). Significant differences were observed in germination rate, turfgrass coverage, turfgrass density and top growth among treatments. Germination rate, density and plant height varied with time after seeding. A proper mix of WSP is considered to be lower than 3% for turfgrass coverage and density. Regarding survival capability and top growth, however, it was good under 6%. Overall KB growth was more influenced by calcium and perlite than chitosan. Calcium and perlite were the most effective elements for early survival capacity and turfgrass density, respectively. But no effect was found by chitosan. Top growth increased with three elements, being perlite > calcium > chitosan. The chitosan was effective in early germination, but there was no effect on top growth until 3 weeks, when compared with others. A further study is needed for investigating the effect of these materials on the growth characteristics in mixtures of sand and SOA before a field application.

  • Crab apple cultivars, 'Maypole', 'Tuscan', and 'Manchurian', were evaluated as potential pollinizers of major apple cultivars, 'Fuji', 'Hongro', and 'Tsugaru', cultivated in high-density apple orchard systems. Numerous cultivar characteristics, including blooming time, pollen germination, fruit set, disease and pest resistance, and self-incompatibility, were examined. The blooming times of both 'Maypole' and 'Tuscan' ranged from April 19 to May 5, which was 2-4 days earlier than those of the major commercial apple cultivars. PCR analysis did not reveal the presence of any of the S-alleles (S1, S3, S7, or S9) identified in major commercial apple cultivars. In addition, the percentage of the fruit set was high after trees were artificially fertilized with crab apple pollen. Artificially cross-pollinated fruits were of similar or higher quality than open-pollinated fruits. They also demonstrated resistance to apple blotch, sooty blotch, and fly speck. The results indicate that the two crab apples, 'Maypole' and 'Tuscan' would be potential candidates for pollinizers of major apple cultivars in Korea. Use of the pollen of these crap apples in commercial production will improve fruit quality and promote sustainable and robust fruit production.

  • Surface sowing method is one of the important methods to establish seeds in mountainous area. Seed-coating technique in the surface sowing method is increasing interest in the world today. An experiment was conducted to develope a technique for pelleting seeds of grass in woodland. Results showed that the seed pelleting was a useful technique than coating seeds because the pelleting reduced coating time and increased amounts of coated seeds per hour. As lowering temperature and reducing time for drying, germinating energy and germination rate of pelleted seeds were improved. And emergence, establishment and early growth of pelleted were also improved in pasture under woodland. Based on this study, we could conclude that the seed pelleting is a useful technique for the establishment and early growth of grass under woodland.
