Tuber yield and content of general component and diosgenin which is a main bioactive property were investigated in order to determine the growth characteristics of round typed yam (Dungeon-ma, Dioscorea opposita L.) and the potential of artificial culture at Suwon, Korea. Sprouting rates of segmented small tubers such as 3, 5, 7, 9, and 12g were respectively 60.3, 80.5, 85.3, 98.6 and 99.3% when they were investigated 30 days after planting. Segmented small tubers of 3, 5, 7, 9, and 12g enlarged respectively to 66, 87, 98, 120, and 140g in the green-house cultivation. Segmented small tubers of 3, 7, 12, 18, and 23g enlarged respectively to 35.2, 124.7, 142.7, 174.8, and 200,7g in the open-air field cultivation.

This study was carried out to investigate the effects of dietary tocotrienol extracted from the rice bran on hematological and histological changes of the mouse. The mice were divided into seven groups (basal diet, cholesterol diet, tocopherol diet, and 4 different tocotrienol diets), and bred for a month. Tocotrienol diet was shown to have decreasing effects of serum triacylglycerol and LDL concentrations, whereas serum HDL concentrations were increased by tocotrienol diet. But serum cholesterol concentration was not statistically significant among the diet groups. Tocotrienol diet was shown to have decreasing effects of serum AST activities (P=0.0548) and LDH activities (P=0.0016), which are the standard indicators for liver damages or myocardial infarction. And tocotrienol diet has reduced the fat bodies accumulated in liver and heart caused from administration of rice bran oil. Also, the effects were shown as concentration-dependent manners. In conclusion, dietary tocotrienol extracted from rice bran has evident effects to protect or reduce lipid accumulation from blood, hepatocytes and heart muscles. It is also suggested as a good fortifying nutrition for the health and medical care.

Shape of soybean sprouts affects their marketability. This study was carried out to understand the effects of pressure in both overspraying and underwatering cultivation methods on growth and morphological characteristics of soybean sprouts. Pressing treatments were done by continuous pressing by laying a plastic culture box over another with growing the sprouts, their alteration every day, or no pressing in overspraying method, and by continuous pressing, pressing after the 4th day cultivation with 30 kg steel case, or no pressing in underwatering method. The soybean (cv. Junjery) seeds were soaked in 2 ppm BA solution for 5 hours and then aerated for 3 hours immediately before 6 day culture. Lateral roots, hypocotyl and root lengths, hypocotyl diameters, fresh and dry weights were measured. Lateral roots per sprout were decreased with stronger pressing regardless of watering methods. In overspraying method, continuous pressing treatment resulted in shortest hypocotyl, but no and ones did the longest root. In underwatering method, however, no pressing one showed the longest hypocotyl but continuous pressing did the shortest hypocotyl. Regardless of watering methods, middle part of hypocotyl was more thickened with stronger pressing although hook diameters of the 3 treatments were not affected. In overspraying method. total fresh weight per sprout was the least in no pressing but the greatest in continuous pressing. In underwatering method, however, there was no significant difference between the treatments.

Heterosis, combining ability, genetic components, effective factor no. and heritability for yield of seed cotton per plant, boll no., seeds per boll, seed length, seed width and lint weight per boll were investigated in
half diallel set of crosses involving diverse upland cultivars. Both heterosis and heterobeltiosis for yield per plant, boll number, seed length and lint weight showed significantly negative values. Both general combining ability (GCA) and specific combining ability (SCA) showed highly significant. Overdominance was observed for yield per plant, boll number, seeds per boll and seed width, complete dominance for seed length and partial dominance for lint weight. The number of effective factor was estimated as two for yield per plant, boll number and seed length and estimated as one for seeds per boll, seed width and lint weight. Narrow sense heritability was low for yield per plant, boll number and seeds per boll. Broad sense heritability was very high for all the characters excepting lint weight.

Pollen grains of seven taxa on the family Pyrolaceae, known to be distributed in Korea (Pyrola dahurica(Andreses) Kom., P. incarnata (DC.) Fisch. ex Kom., P. japonica Klenze ex Alefeld, P. minor L., P. renifolia Max., Orthilia secunda (L.) House, Chimaphila japonica Miq.), were examined by the light and the scanning electron microscope in order to evaluate their taxonomic significances. The pollen units of genus Pyrola, Orthilia, Chimaphila were tetrad, monad, polyad respectively. This characteristics was good character for delimiting the genus, and Orthilia secunda (L.) House was more proper scientific name than Pyrola secunda L. based upon this character. Pollen size, tricolporate length, surface sculpturing pattern were different slightly among the treated taxa, and surface sculpturing patterns of Pyrola dahurica, P. incarnate, P. renifolia, Chimaphiza japonica were different from previous reports. Evolutionary trends of pollen grains in Pyrolaceae were inferred from the pollen units and aperture shapes.

Root colonization by a rhizobacterium, Pseudomonas chlororaphis O6, elicited induced systemic resistance (ISR) in the leaves of cucumber plants against fungal and bacterial pathogens. To understand the role of unique genes during strain O6-mediated ISR, a suppressive subtractive hybridization method was undertaken and led to isolation of twenty-five distinct genes. The transcriptional levels of all the genes showed an increase much earlier under O6 treatment than in water control plants only after challenge with pathogen, while no difference detected on the plants without pathogen challenge. This suggests that O6-mediated ISR is associated with the priming phenomenon, an enhanced capacity for the rapid and effective activation of cellular defense responses after challenge inoculation.
