The effects of angiogenesis inhibitor from the extract libraries of Korean and Chinese medicinal plants were investigated using a protein microarray chip. Protein chip was constructed by immobilization of integrin α5β1 on protein chip base plates and employed far screening active extracts that inhibit the integrin-fibronectin interaction from the extract libraries. The 100 extracts of medicinal plants were obtained from extract bank of National Institute of Crop Science, RDA. The 14 extracts among 100 extract libraries were shown efficient inhibition activity for the interaction between integrin-fibronectin. The medicinal plants of 14 extracts were Vitex negundo var. incisa (Lam.) C.B. Clarke, Epimedium koreanum Nakai, Cedrela sinensis A. Juss, Ipomea aquatica Forsk, Schisandra chinensis Baill, Pulsatilla koreana Nakai, Paeonia lactiflora Pall. var.hortensis Makino, Oenothera odorata, Allium chinense, Allium victorialis var. platyphyllum MAKINO, Polygonatum odoratum Druce var. pluriflorum Ohwi, Hosta lancifolia, Agrimonia pilosa L. var. japonica Nakai and Potentilla chinensis SER. The Paeonia lactiflora, Oenothera, and Agrimonia pilosa from these 14 extracts libraries were shown strong inhibition activity of integrin α5β1.

Sanho is a new japonica rice cultivar with brown pericarp color (Fig. 1). This cultivar was developed from the cross Ilmibyeo//Ilmibyeo/Pyeongtaekaengmi 4, where the recurrent parent Ilmibyeo is a japonica cultivar with high eating quality, and the donor

This experiment was conducted on rice (cv. 2005 Thaoi) seeds to study whether priming with deep sea water (DSW) results in enhancement of seed emergence and seedling growth and to identify the optimum concentration of Deep Sea Water (DSW) for priming. Two experiments were conducted subsequently. In experiment 1, four concentrations of the DSW (10%, 20%, 30% and 40%), and in experiment 2, five concentrations of DSW (10%, 15%, 20%, 25% and 30%) were prepared and seeds were primed for 24 hours duration at 25℃. Beside this, hydro priming with plain water was also included as a control. Experiments were laid out in Completely Randomized Design (CRD) with three replications. Result showed that 20% DSW seed priming treatment had improved the emergence, seedling height, number of roots and root length as compare to other with DSW or without DSW treatments. Beyond 20% DSW priming (i.e. 25%, 30% and 40%) were not suitable for priming the seed. On the basis of seedlings growth parameters; emergence, seedling height, root number and length, and shoot root ratio, 20% DSW priming was the best priming treatment.

This experiment was conducted on wild vegetables; Gondalbi (Cirsium setidens), Deoduck (Codonopsis lanceolata Trautv.), and Jandae (Adenophora triphylla var. Joponica Hara) seed to study whether priming with deep sea water results in enhancement of seed germination and identify the optimum concentration of the priming solution, and duration of priming. Seeds were primed with 5 various concentrations (5%, 10%, 15%, 20% and 30%) of deep sea water (DSW) in 12 hours, 24 hours, and 48 hours at 24℃. Since Jandae had seed dormancy, it was kept for four weeks in refrigerator at 2℃ after priming treatment. In Deoduck, 5 percentage DSW priming significantly improved the early germination percentage, radicle length, and plumule emergence percentage. Among the priming period of treatments, 24 hours priming showed better performance in this treatment whereas, in Jandae, 12 hours priming with 10 percentages DSW significantly improved the germination percentage and germination rate. This treatment had increased the final germination percentage by 54%, 15% and 40% compared with control, plain water and KNO3 priming respectively. But in Gondalbi, priming did not improve the germination of seed. However, among the priming treatments, 12 hours priming with 3% KNO3 and 20% DSW gave better performance. In both the wild vegetables; Deoduck and Jandae, priming in deep sea water had improved the germination percentage and germination rate as compare to plain water, KNO3, and without priming treatment. Hence the best seed priming treatment on Deoduck and Jandae are 24 hours with 5% DSW and 12 hours with 10% DSW respectively.

The experiment fields consisted of five plots as follows; 2, 4, and 8 tonsㆍha⁻¹ citrus skin in combination with starch sludge and pig manure mixing compost (CSSP), 4 tonㆍha⁻¹ fermented pig manure compost (FPMC) treated plot, and untreated control. Plant height and stem diameter were significantly increased by CSSP. Most of all, average tuber weight and tuber yield per plant were significantly increased in 4 and 8 tonsㆍha⁻¹ CSSP plots compared to the other plots. Marketable tuber (＞50 g fresh weight) yield were superior in order of 4 and 8 tonsㆍha⁻¹ CSSP plot, 4 tonsㆍha⁻¹ FPMC plot, and 2 tonsㆍha⁻¹ CSSP plot.
