Background : The aim of the present study was to identify an effective physicochemical control method to reduce Fusarium species infestation in adlay (Coix lacryma-jobi L.) before and after harvesting. Methods and Results : We observed that prochloraz emusifiable concentrate and hexaconazol prochloraz emusifiable concentrate strongly inhibited the mycelial growth of 10 Fusarium species. Strong growth inhibitions and cell lysis were observed following treatment with 4% NaOCl solution. The total number of fungi detected were lower follwing treatment with thiophanatemethyl triflumizole wettable powder (), hexaconazol prochloraz emulsifiable concentrate (), carboxin thiram dustable powder () and prochloraz emulsifiable concentrate () than in the non-treated control (). The reduction of Fusarium fungi varies with the concentration and soaking time of NaOCl solution. Fungal detection was not observed after soaking in NaOCl solution for 24 h and harmful effects were not observed for plant growth by NaOCl after soacking for 6 - 12 h. Conclusion : Soaking seed for 6 - 12 h in 4% NaOCl could be an effective method of disinfectant treatment for the control of Fusarium fungi in adlay seeds.

Background : This study examined the effect of harvesting time on the growth, yield characteristics, and major beneficial components in Salvia miltiorrhiza. Methods and Results : Although plant height, stem diameter and branch length were not affected by harvesting time, the number of stems was highest when harvested in mid October. There were no differences in root length and thickness, however, the rhizome was thicker when it was harvested at the end of October or early November than when it was harvested in early and mid October. The dried root weight also showed a similar pattern. However, there was a statistically significant increase to 408 kg (16%) in the rhizome weight when in late October and a rise to 455 kg (29%) when harvested in early November. Harvest time had little effect on the content of the major component of S. miltiorrhiza. For example, salvianolic acid content rose from 9.42 to 9.64% with later harvest times, and tanshinone content was tended to be slightly more increased in mid October which S. miltiorrhiza has 0.22% tanshinon than in early October. Conclusions : According to these results, the optimum harvest time for S. miltiorrhiza is early November when plant or major component yields are hightest. There were no significant harvest time effects on the major beneficial components.

The shape of fruit was oval with light browncolor. Fruit was mericarp, biloculate, with one ovule in each locus. The length and width of seed were 1.37±0.067 ㎜ and0.52 ±0.039 ㎜, respectively. Weight of 1,000 seeds was 6.55±0.15 g. Seeds which were stored at room (15℃) and cold tem-perature (4℃) in vinyl container showed the highest germination rate (93.3%) under the room temperature germinationcondition. Percentage of germination in cold and freeze temperature was 20% and 0%, respectively. Germination rate ofroom storage seeds with paper container increased to about 91.3%, however, decreased in cold (4℃) and freeze storage (−20℃)with paper container (76.7% and 78.0%, respectively). Germination rate of seed in vinyl stock container was better thanthat of paper stock container. Germination rate of seeds stored at room temperature for 4 years (2010 - 2013) ranged from80.0% to 91.3%. Therefore, coriander seeds are expected to be stored at room temperature for increasing the germinationrate and keeping a long term.Key Words : Coriandrum sativum L., Germination Temperature, Seed Characteristics, Storage Condition
