  • This study was carried out to investigate residual characteristics of insecticide acetamiprid in asparagus under greenhouse condition from July to August and consequentially to obtain basic data for guideline on safe use of this pesticide in asparagus. Residues of acetamiprid in young stem of asparagus before and after removing foliage were analyzed from samples harvested at 0, 1, 3, 5 and 7 days after single application before harvest. As a result, residues of acetamiprid in young stem of asparagus before and after removing foliage at 0 day were 0.27 mg/kg and 0.14 mg/kg, respectively, which were higher than tentative limit (0.1 mg/kg). However, 3 days later residues of acetamiprid were lower than the tentative limit, representing 0.08 mg/kg and 0.03 mg/kg in the asparagus before and after removing foliage, respectively. Acetamiprid was undetectable in both samples at 5 days since the concentrations were less than detection limit (0.02 mg/kg) in this study. In summary, the half-life of acetamiprid in asparagus regardless of removing foliage was quite short under greenhouse condition from July to August, in the range of 1-3 days, and single application of acetamiprid water dispersible granule in/on asparagus at 7 days before harvest would have no problem on safety issues about pesticide residue. This result might be basic information to construct guideline for safe use of acetamiprid in asparagus.

  • An in vitro and in vivo studies were conducted to evaluate the antibacterial efficacy of certain botanicals viz., rhizomes of turmeric (Curcuma longa) and leaves of amla (Phyllanthus emblica), asparagus (Asparagus racemosus), bael (Aegle marmelos), boerhavia (Boerhavia diffusa), garlic (Allium sativum) and basil (Oscimum basicilum) against bacterial pathogens viz., Staphylococcus sp., Bacillus sp. and Klebsiella cloacae, of silkworm, Bombyx mori. Asparagus and basil, amla and boerhavia, basil and bael at concentration of 20, 000 ppm showed higher antibacterial activity against Staphylococcus sp., Bacillus sp., K. cloacae respectively, both in vitro and in vivo studies.

  • A human hepatoma cell line, Hep G2 cells are a reliable for the study of alcohol-induced hepatotoxicity. In this study, the author investigated the effect of an aqueous extract of Asparagus $cochinchinensis_{MERRIL}$ (Liliaceae) roots (ACAE) on ethanol (EtOH)-induced cytotoxicity in Hep G2 cells. ACAE dose-dependently inhibited the EtOH-induced tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$ secretion. ACAE also inhibited the EtOH and $TNF-{\alpha}-induced$ cytotoxicity. Furthermore, the author found that ACAE inhibited the $TNF-{\alpha}-induced$ apoptosis of Hep G2 cells. These results suggest that ACAE may prevent the EtOH-induced cytotoxicity through inhibition of the apoptosis of Hep G2 cells.

  • Antidiabetic treatment with tubers of Asparagus racemosus (Liliaceae) extract (l00 and 250 mg/kg body weight) for three weeks showed significant reduction in thiobarbituric acid reactive substances (TBARS) and glutathione reductase (GSH-R) in both liver and kidney. The treatment with A. racemosus significantly altered the glutathione (GSH) and GSH-R to be comparable with the control group. A. racemosus and glibenclamide treated rats showed decreased lipid peroxidation that is associated with increased activity of superoxide dismutase (SOD) and Catalase (CAT). The ability of A. racemosus on tissue lipid per oxidation and antioxidant status in diabetic animals has not been studied before. The result of this study thus shows that though, A. racemosus possesses moderate antidiabetic activity, but it exhibits potent antioxidant potential in diabetic conditions.

  • The methanol extract of Asparagus racemosus root was evaluated for its anti-inflammatory activity on carrageenin and serotonin-induced rat hind paw oedema models. The extract (200 and 400 mg/kg) showed maximum inhibition of oedema of 18.6% and 33.7% at 3 h with carrageenin and 22.2% and 40.5% at 5 h with serotonin-induced rat paw oedema respectively. The experimental models tested, where the effect produced by the extract was compared to that of phenylbutazone, a prototype non-steroidal anti-inflammatory drug.

  • This study was conducted to determine the ideal beginning date of plastic house optimum heating for off-season (December) production of asparagus. To achieve this, the 1.6-year-old 'Green tower' asparagus was cultivated in Jeju area ($33^{\circ}$28.110N, $126^{\circ}$31.076E) and the yield and quality among 7 different beginning dates of heating from Oct. 25 to Jan. 20 with 15-days interval were compared. The heating was controlled to maintain the inside temperature was higher than $20^{\circ}C$, But the plastic house was ventilated when the inside temperature rose to $30^{\circ}C$. Days to sprouting took longer as heating dates were delayed. Days to sprouting took 52 days in heating at December 30, and the days were shortened thereafter. As the beginning of heating was delayed, sprouting of asparagus was retarded. Among treatments, days to sprouting was 52 days and longest when the heating began on December 30. When the heating began on October 25, harvest was earliest and started on 7 November. When the heating began on November 15 and 30, harvest started on November 30 and December 18, respectively. Harvesting started on November 7 for October 25 heating, November 30 for Nov. 15 heating, and December 18 for November 30 heating, respectively. When the heating began was done after December. 15, harvesting was possible after early January. The number of spear, spear weight and yield were highly increased in the treatments of heating after January. 10 when the asparagus dormancy was broken. In the case of heating dates were before the asparagus dormancy breaking, the total yield was highest in November 15 heating with 607 kg/10a. The marketable yield of November 15 heating was 386kg/10a, which was twice higher than the 193 kg/10a of October 25 heating. Accordingly, it is recommended to start heating on November 15 for the production of off-season (December) asparagus in Jeju. Therefore, the optimum heating date to start was November 15 for the improvement of quality and yield of off-season (December) asparagus in Jeju area.

  • To analyze the genetic relationships among 23 accessions of Asparagus cochinensis $L_{OUR}$, random amplified polymorphic DNA(RAPD) analysis was performed using artificially synthesized 10 primers. The range of polymorphism was $42.9{\sim}91.7%$ with an average of 72.9% in 85 randomly and specifically amplified DNA fragments. On the. basis of similarity coefficient analysis by unweighed pairgroup method, arithmetic average method(UPGMA), 23 accessions of Asparagus cochinensis $L_{OUR}$ could be classified into 6 groups at the similarity coefficient value of 0.82. Group I contained 5 accessions, Group II contained 6 accessions, Group III contained 6 accessions, GroupIV contained 2 accessions, Group V contained 2 accessions and Group VI contained 2 accessions. The range of total genetic similarity coefficient value of 23 accessions of Asparagus cochinchinensis $L_{OUR}$ was $0.47{\sim}0.92$ and average value was 0.76. To obtain more exact data from PCR, we also tried to develope enhanced RAPD techniques using Bovine Lacto Transfer Technique Optimizer(BLOTTO). In RAPD analysis of Asparagus cochinensis $L_{OUR}$, we could obtain better RAPD results by adding BLOTTO at a final concentration of 1%.

  • This study was conducted to identify the effects of 1-MCP and the storage methods for maintaining the quality of asparagus spears. Asparagus spears treated 1-MCP stored in MA condition and perforated film (conventional condition) and 1-MCP non-treated used as control. The treated asparagus was stored at $4^{\circ}C$ for 40 days. The fresh weight loss rate was less than 0.2% in all MA (Modified atmosphere) storage treatments, including the 1-MCP treatment, and 1-MCP shown the less fresh weight loss rate in perforated film storage after 20 days storage. The carbon dioxide concentration within a package was 5-12% in MA storage, which is whith the tolerated range of maximum $CO_2$ content of asparagus spears in recommended CA or MA conditions. The oxygen content was maintained between 5 to 15% in MAP treatments. The ethylene content was lowest at the MA storage with 1-MCP treatment. Visual quality, off-flavor, soluble solid contents, and hue angle on the final storage day were higher in MA storage and the 1-MCP treatment and conventional MA storage did not show any significant differences. These results suggest that the 1-MCP treatment did not significantly affected the quality and storability of asparagus spears.
