  • There are some international standards and organization controling the quality characteristics of varieties and seeds such as UPOV, OECD, ISTA, AOSA. The National List system to check variety performance such as quality characteristics of plant varieties and seeds was established by each countries. The UPOV (International Union for the Protection of New varieties of Plant) regulates the requirement of plant variety protection that is distinctness (D), uniformity (U), stability (S) (here in after called DUS), Novelty and Denomination, and some quality characteristics are used to examine the requirement of plant variety protection by each crops. OECD (Organization for Economic Cooperation Development) seed scheme regulates the seed certification for seed trade between countries. ISTA (International Seed Testing Association) and AOSA(Association for Official Seed Analyst) regulates the seed analysis standard and methods. Most of the countries in Europe has the National List system, which check the value for cultivation and use(VCU), that is to say, variety performance such as yield, quality and stress to environment. All the seeds should be enlisted in the National List before sell the seed in their country. All the quality characteristics checked variety performance are for instance, amylose and amylopectin content in rice, molting quality, $\beta$-glucan, protein in barley, protein and sugar content in soybean, sugar and amylopectin content in corn etc. Conditions for the protection of new variety of plant are DUS. Quality characteristics may be the important characteristics and used to check DUS in crop by crop. It is very important to develop a new characteristics and establish standard method fur examine the VCU and DUS test for each crop.

  • Wild soybean plants(Glycine ussuriensis) collected from Korea(47 strains) and abroad(41 strains) were grown under field condition and classified according to the growth habit. Seeds were analyzed for protein content. The results were as follows: 1. Wild soybean plants were classified into three groups each by seed size, growth habit of stem, leaf size and flowering time. 2. Seed protein was higher in the strains with large leaves, tendril, stem or late flowering. 3. Glycine gracilis, supposed to be the intermediate species between cultivated and wild soybean(according to the stem growth habit, straight or semitendril, and seed size) was medium in protein content of seeds. 4. The average protein content of Glycine ussuriensis, 43.2%, was highest in comparison with those of others such as G. gracilis, 37.5%, or G. max, 36.2%. 5. One hundred seed weight of Amphicarpaea trisperm, similar to the wild soybean, was almost same as Glycine ussuriensis, but protein content of this species was lower than wild soybeans.

  • This study was carried out to obtain informations on the variations of oil content and fatty acid composition among 90 Korean perilla collections. Average oil content of 90 perilla collections was 44.2% with a range from 29.7% to 61.9%. Perilla collections with late-maturing, super-large seed and gray seed coat showed higher oil content than other types in general. Average saturated fatty acid content in perilla oil was 9.0% with a range from 8.2% to 10.7%, while average unsaturated fatty acid content varied from 89.3% to 91.8% with a mean of 91.0%. Contents of saturated and unsaturated fatty acids were not related to maturity. There were no differences in the contents of saturated and unsaturated fatty acids according to maturity. Linoleic acid and linolenic acid contents were the highest in the super large-sized group(15.5%) and in the large-sized seed group(61.4%), respectively, while contents of fatty acids among the perilla collections were variable with different seed coat colors. Most of the traits studied were not significantly correlated with oil content, but linoleic acid($\omega$-6) content was negatively correlated (r=-0.217*) with linolenic acid($\omega$-3) content.

  • Soybean quality is determined based on protein content, lipid content and fatty acid composition, and several functional components including isoflavones, anthocyanins and functional activity. Because the level of each component changes during seed development, it is necessary to know the concentration of quality-related components in developing seeds. Little is known of the pattern of changes in quality-related components. Seeds from field-grown soybean was harvest from the $R_6$ stage to the $R_8$ stage in 2004. Seed characteristics and the level of nutritional components were examined. Seed moisture content was dropped rapidly after the $R_7$ stage in the tested varieties. Seed growth rate was the highest from the beginning of the $R_6$ stage to the mid-$R_6$ stage. Chlorophyll content was decreased rapidly in pods and seeds. However, seed growth period from the $R_6\;to\;R_8$ was 35 days. The crude protein content was. increased dramatically between 63 DAF and 70 DAF and then increased slightly. The pattern of isoflavone accumulation was nearly similar to that of seed weight increase. From the late $R_6$ stage to the $R_7$, the accumulation rate was higher as compared to other stages. The angiotensin inhibitory activity was increased according to seed development from 63 ($R_6$) to 84 DAF ($R_8$). The difference of inhibitory activity in heated soybean powder, however, was not great among stages. The inhibitory activity was affected by heating treatment. The most effective heating time was 10 min. Excessive heating longer than 30 min resulted in a lowered inhibitory activity of soybean on ACE.

  • Recently, geofiber(polyester) reinforced soil was added on soil-seed mixture spray to control erosion and to improve vegetation growth on rocky slope sites. This research was conducted to compare vegetation effects and soil hardness on three types of soil-seed mixture spray on stone gabion river bank [A type : soil-seed mixture spray underlying 30cm thick sand with geofiber(geofiber reinforced soil system), B type : soil-seed mixture spray underlying 30cm thick sand without geofiber, C type : soil-seed mixture spray]. Evaluation were made concerning vegetation coverage, soil hardness and moisture content. The results of this study showed that A type system was effective for the growth of vegetation and soil hardness when compareed to B type and C type. A type and B type showed higher covering rate than C type on stone gabion river bank, and especially A type showed the highest covering rate. Soil hardness and water content were high on A type vegetation system compared to B type and C type. We noted that high soil hardness and high moisture content with geofiber(geofiber reinforced soil system) were effective both to control erosion from water current impact and to be high coverage and species of vegetation on stone gabion river bank.

  • Sucuk is the most popular dry-fermented meat product. Sucuk has a relatively high fat. Poppy seed oil as animal fat replacer was used in Turkish sucuk and effects of its use on sucuk quality were investigated. There was a significant (p<0.5) treatment × ripening time interaction for moisture, pH (p<0.05) and 2-thiobarbituric acid reactive substances (TBARS) values (p<0.01). Increasing poppy seed oil level decreased (p<0.05) TBARS values. Addition of poppy seed oil to the sucuks had a significant effect (p<0.01) on hardness, cohesiveness, gumminess, chewiness and springiness values. Cholesterol content of sucuks decreased (p<0.05) with poppy seed oil addition. Using pre-emulsified poppy seed oil as partial fat replacer in Turkish sucuk decreased cholesterol and saturated fatty acid content, but increased polyunsaturated fatty acids. Poppy seed oil as partial animal fat replacer in Turkish sucuk may have significant health benefits.

  • Dynamic parameters of biochemistry including the contents of soluble carbohydrate (SC) , crude fat (CF) , fatty arid (FA) and soluble protein (SP) in American send (Panax qufnquelolium L.) seed are reported in the present paper. When embryo ratio (ER) increased from 7.31 to 20.48%, the SC content decreased from 4.08 to 1.16%. After that, SC content changed little. The CF content decreased successively from 34.50 to 14.40% from the beginning to the end during the embryo afterripening. The changes of FA content did not correlate with that of ER and the changing range of SP content was not large during the seed stratification. All of these may provide some information for understanding the dormancy mechanisms of American seng seed.
