Safflower (Carthamus tinctorius) seeds are wellknown traditional oriental medicines that have long been used for the remedies of blood stasis and bone formation in east Asia. In this study, ethyl acetate (EtOAc) was used for extraction of the main chemical compounds from C. tinctorius seeds. Four major compounds were identified, acacetin, cosmosiin, N-feruloyl serotonin and N-(p-coumaroyl) serotonin. Each compound was evaluated for its inhibitory activity against the inflammatory process of macrophages. All compounds significantly inhibited production of lipopolysaccharide (LPS)-stimulated nitric oxide (NO) and pro-inflammatory cytokines. The protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were dramatically decreased by serotonins in a dose-dependent manner in LPS-stimulated RAW 264.7 macrophages. These results suggest that serotonin derivatives from safflower seeds may reduce inflammation-related diseases.

Many antinutritional and toxic factors abound in tropical seeds, which are also generally rich in nutrients and therefore more prone to attack from herbivores. Antinutritional and toxic factors are considered to defend seeds against environmental vagaries and thus help to protect them. These factors though good for the plant, cause deleterious effects or are even toxic to animals and man. The conventional seeds cultivated for oil or non-oil purposes, and general aspects of antinutritional factors are not presented here as these have already been discussed widely by many workers. Deficits in conventional protein and energy sources in the tropics have stimulated a quest for alternative feeds both for animals and humans. This article attempts to highlight two new oilseed crops, Jatropha curcas and Moringa oleifera, and in addition deals with some under-utilized seeds with potential as animal feed. Most of these seed plants are adapted to various marginal growing conditions in the tropics and can help to mitigate the prevailing deficit in protein and energy sources. Antinutritional and toxic factors in seed or seed meal, various approaches to detoxify seed meal, and future research and development priorities for their exploitation as animal feeds are presented.

Persimmon seeds contain considerable amounts of minerals, amino and organic acids, natural antioxidants and phenolic compounds. The objective of this study was to investigate quality characteristics and antioxidant potential of Korean persimmon seeds. The pH (4.88-4.94), color values, contents of minerals, free amino acids, organic acids, and phenolic compounds and DPPH free radical scavenging potentials of persimmon seed extracts significantly (p < 0.05) varied with the genotypes. This study showed that the seeds could be used as a source of different mineral elements (47.14-85.07 mg/kg) without any measureable amount of heavy metals such as arsenic, cadmium, lead and mercury. Similarly, considerable amounts of organic (1550.13-2413.08 mg/kg) and essential amino (50.85-54.03 mg/kg) acids and total phenolic compounds ($1227.91-1307.78{\mu}g$ gallic acid equivalent/g) were also found in the seed extracts, indicating their potential food value as a natural antioxidant. Results of the present study imply that prethanol-A, a food preservative, can be used as an effective extraction to obtain the minerals, organic and free amino acids, and phenolic compounds from the persimmon seeds, which possess a big potential to be commercially used in food, cosmetic and pharmaceutical industries.

택사 종자의 펠렛화를 위한 피복 재료를 선발하기 위해 기존에 개발되었거나 농업적으로 이용 가능한 재료들을 사용해 본 시험을 수행하였다. 펠렛 종자의 모양형성은 피복 재료의 종류에 따라 좌우되었으며 대체로 단용재료나 2종의 혼합재료에 비해 3종의 혼합재료가 펠렛 형성이 잘되고 수분 흡수후 펠렛의 열개성이 우수했다. 특히 SDZ+DE+CA $0.4\%$의 혼합물이 발아율 및 발아세가 $95.3\%$로 가장 높았고 생력 기계파종을 위한 물리적 특성도 좋아 펠렛 종자의 피복 재료로 가장 양호하였다.

The aim of this work is to evaluate the potential of oriental melon (Cucumis melo L. var. makuwa Makino) seeds for the management of type 2 diabetes by controlling glucose absorption. The ${\alpha}$-glucosidase and ${\alpha}$-amylase inhibitory effects of the hexane extracts from oriental melon seeds were investigated. A bioassay-guided fractionation technique was used to elucidate the principal active components. The results show that the hexane extract from oriental melon seeds exhibited high inhibitory activities against ${\alpha}$-glucosidase and ${\alpha}$-amylase. The hexane extract was further fractionated into four sub-fractions. Among them, the sub-fraction F-1 exhibited the most potent anti-diabetic effect. The active components were isolated and identified by gas chromatography/mass spectroscopy (GC-MS). Free fatty acids showed significant hypoglycemic activity (p < 0.001) and fatty acid composition influenced enzyme inhibitory activities. These results suggest that oriental melon seeds could be used to prevent type 2 diabetes.

Background: Newly introduced transgenic plants can outcompete native species in natural ecosystems, threatening the biodiversity of a country. This study ascertained the weediness potential of plants according to the seed amount under the assumption that transgenic seeds were unintentionally spilled. Using sunflowers as the study system, 0, 50, 100, and 150 seeds were sown in 1 m × 1 m and 2 m × 2 m plots, and seed germination, survival, flowering, and competition between the surviving and wild plants were investigated. Results: There was no significant difference in the germination rate of sunflowers depending on the cultivar, but differences were observed depending on the sowing density and plot size. As the number of seeds sown increased, the flowering and seed maturation of sprouted plants occurred earlier; the plant height and flower length of the surviving plants decreased. In addition, as the number of seeds increased, not only did the early importance of sunflowers increase, but the period of dominance over weeds also improved. Conclusions: These results suggest that the weediness potential of sunflowers varies with the number of seeds at the time of release, which may affect germination and growth, and compete with weeds in transgenic plants.

인삼은 다년생 식물로 종자 번식을 하는데, 수확 시 미성숙한 배(embryo)를 가지고 있어 후숙이 필요하다. 기후변화에 대비하고 안정적인 종자 보급을 위해서는 단기 및 장기간 대량으로 종자를 저장할 수 있는 기술이 필요하다. 본 연구에서는 2개 지역에서 얻은 개갑된 인삼 종자를 수분함량을 달리하여 -3.5℃에 보관하고, 저장 3, 15, 27개월 후에 유근과 지상부 출현을 관찰하여 발아력 검정을 통해 종자 저장성을 조사하였다. 3개월 후, 전반적으로 batch #1보다 batch #2에서 발아율이 높았고, 그리고 수분함량이 35% 이상에서만 발아가 원활하였다. 15개월 후, batch #2에서 수분함량이 45~54%인 부분 건조된 종자들에서 가장 높은 발아율을 보였고, 대부분의 무건조 종자는 부패하며 발아에 실패하였다. 수분함량 25% 이하로 건조된 종자들 역시 유근발아 또는 출아가 불량하였다. 부분 건조 종자들은 토양에서의 발아 및 생육도 우수하였지만, 1년 뒤에는 역시 활력을 유지하지 못하였다. 요약하면, 인삼 종자는 온대성 난저장 종자의 특성을 가지는 것으로 보이며, 부분 건조 조건에서는 종자의 수명을 연장할 수 있어 1년 정도의 단기 저장에 활용할 수 있을 것으로 판단된다.

In order to increase the germination speed and uniformity of tomato seeds, sonication and modified drum priming treatments were investigated to produce high quality seeds for export. Sonication treatment was performed for 5, 10 and 20minutes at an intensity of 5.2, 10.4 and 15.7kHz in water at $15^{\circ}C$. After sonication treatment, seeds were primed with water or 100mM $KNO_3$ for 4days. 40, 50 and 60% seed moisture content (SMC) of hydrated seeds were incubated for 60, 72 and 84h in a container with a relative humidity of 99% at 26rpm for a modified drum priming treatments. Germination speed were highly improved by sonication with osmotic priming. The seed treatment of osmotic priming or hydro priming after sonication or sonication without priming enhanced germination percentage (GP) on the $2^{rd}$day after sowing to 46%, 43% and 28%, respectively, while untreated seeds resulted in only 1% GP. These treatments also highly improved mean germination time (MGT) to 1.4, 1.8 and 2.6days, respectively, when compared to 3.5days MGT of untreated seeds. The modified drum priming treatment (72h incubation after 60% SMC hydration) significantly improved results of 74% GP(on the $3^{rd}$day after sowing), 2.6days MGT and $39%{\cdot}day^{-1}$ germination rate (GR), however, untreated seeds showed 19% GP, 4.1 MGT, and $25%{\cdot}day^{-1}$ GR. Although osmotic priming after sonication, hydro priming showed similar improved germination characteristics, however, modified drum priming is considered as an industrially promising treatment methods considering the shortening of the treatment period and environment-friendly aspects.
