This research was carried out to obtain the field resistance to disease and pest, and high yielding of new Boxthorn (Lycium chinense Mill.) varieties. Growth characteristics, yield potential, correlation of trait which was related the yield and path coefficient of the domestic native varieties. two of cultivated varieties and four of introduced varieties were investigated. In growth characters of collected varieties, the stem length of collected varieties in China were slightly long. Leaf area in Jindo, Kumsan native and Yusong 1 and 2 were wider than that of other varieties. Resistance to pest iniury was very strong at China 1, Japan 1 and Yusong 2 in eriophyidmite, and also resistance to anthrax anthracnose were showed less than 10% of the rate of attack fruit at Japan 1 and China 1. Flowering stage was more early in Chungyang native than that of other varieties. Fruit size of Kumsan native, Yusong 2 were large size fruit varieties. Fruit setting number was most abundant at 1,623 in Yusong 2 which was collected variety. And dry yields of fruit per lOa was more cmparatively abundant in Yusong 2 at 86% than those of Chungyang native. The high correlation cofficienct character with fruit yield were fruit setting and branching number and leaf area. Direct effect by path anaslysis were fruit setting number (Py=0.45), and branching number was showed indirect effect.

This study was carried out to develop the propagation system using in vitro induced- microtubers of yams (Dioscorea alata L.). Effects of kinds of media, mineral composition, sucrose concentration (0, 2, 4, 6, 8, 10%), photoperiod (0, 8, 12, 16, 24h), and growth regulators (NAA, IAA, ZR, JA-Me, ABA) on the development of microtubers, roots, and shoots in nodal stem segment cultures of D. alata L. were evaluated. Microtuberization in nodal stem segment occurred on all the media supplemented with growth regulator and sucrose. Among basic media, 1/2MS medium was the best in microtuber induction. NAA was shown to be the most effective among the growth regulators. Optimal NAA concentration was 1mg/l. The microtuberization was the highest at the concentration of 6% sucrose. When the nodal stem segment were cultured under darkness, the tuberization was increased markedly compared to those cultured under light condition. It was also noticeable that the culture in medium with NAA produced only microtubers and roots, but no shoots, in nodal segments. In this study, the optimal medium composition for microtuberization in nodal stem segment was found to be 1/2MS medium supplemented with 1mg/l NAA and 6% sucrose under dark condition at

In 1998, there was heavy precipitation of 60 days with amount of 1,042mm from June to September in Andong. Upland crop was severely injured by excessive moisture(EM) on poor drainage field. In this trial, effects of EM on the growth characteristics and yield in Peucedanum japonicum Thunberct and Rehmannia glutinosa Liboschitz was investigated. In Peucedanum japonicum Thunberct, growth of root was decreased more severely than that of aerial part by EM injury, and fresh weight of root per ha was decreased by
at different degree of EM injury compared to that of normal growth. In Rehmannia glutinosa Liboschitz, percent of withered plant was
at different degree of EM injury. and rhizome's number per plant and diameter was extremely decreased by EM injury. Fresh weight of rhizomes per ha was decreased by
at different degree of EM injury compared to that of normal growth.

This experiment was conducted to determine effects of trenching depth on characteristics and yield of tubers in Chinese yam (Dioscorea opposita Thunb). Self-propelled trencher, ‘NF-827H’ produced by KAWABE company, was used for trenching. When trenched, tuber's length and weight were longer and heavier, tuber's shape was better, and marketable tuber yield was remarkably increased than those of conventional plowing and soil preparation by a tractor. The size and yield of tubers were greatly enhanced by trenching in long-tuber variety than that in short-tuber variety. The depth of trenching is recommended to be more than 60cm for short-tuber variety and more than 80cm for long-tuber variety considering the size, shape and yield of the tllbers.

The saponins are considered the main effective components in Platycodon grandiflorum (Jacq.) A. DC.. In order to obtain the basic information for producing the high quality medicinal plant and processing, the crude saponin contents were analyzed with platycodi radix, the root of Platycodon grandiflorum by different cultivating years, parts, harvesting times and drying methods. The crude saponin contents were decreased by increasing cultivating years. The crude saponin contents were 2.74% in tail of root and 1.65 % in head of root, respectively. Besides, the contents of the crude saponin in cortex were 1.8 times more than that in core of root. The crude saponin contents in different harvesting times were 2.82% and 2.74% at March 10 and December 10, showing higher than that being harvested at June 10 and September 10. The crude saponin contents among drying methods were not significantly different at 5% level DMRT, but the hot air drying after steam showed the least crude saponin.

Four different parts of Hovenia dulcis
; fruit, bark, vessel area, fruit coat were extracted with water and ethanol. The ethanol extracts of bark, fruit coat and fruit were fractionized into diethyl ether, chloroform and aqueous partitions. Ethanol extract of fruit coat increased the activity of cathepsin B up to 55 %, which can enhance the alcohol dehydration in the liver. The ethanol extracts was more effective than water extracts against the growth of Hep3B, MCF7. The ethanol extracts of bark (0.5mg/ml) inhibited 90% the growth of MCF7. Each extracts and fractions (0.5mg/ml) did not show considerable cytotoxicity on HEL299. In overall, most of the fractions had similar effects to ethanol extracts; however, diethyl ether and chloroform fractions had higher bioactivity than ethanol extracts, but aqueous fraction.

This study was conducted to establish the standard of quality evaluation in Korean cultivated peony root(Paeoniae Radix). The diameter of fresh root and the concentrations of paeoniflorin, abliflorin and five phenolic compounds at different root ages in Euisung cultivar were investigated. The diameters of fresh root were 5.5mm, 10.3mm, 15.6mm and 19.1mm in one-year, two-year, three-year and four-year-old, respectively. It was also found that the diameter of fresh root was uniformly increased with the increase of root age. The concentrations of paeoniflorin, albiflorin, (+) -catechin and benzoic acid in one-year-old peony root(6.44%, 1.55%, 0.80% and 0.36%, respectively) were higher than those in three-(3.49%, 0.62%, 0.43% and 0.26%) or four-year-old(3.28%, 0.47%, 0.34% and 0.20%). The concentrations of gallic acid, (-) -epicatechin and (+) -taxiforin
were higher in three- (0.26%, 0.09% and 0.26%, respectively) or four-year-old (0.26%, 0.10% and 0.29%) than those in one-year-old (0.25 %, 0.08 % and 0.23 %) by contraries. Excepting (-) -epicatecin, the concentrations of paeoniflorin, albiflorin and four phenolic compounds in the root of unremoved cork layer were higher than those in the root of removed cork layer.

Ligusticum chuanxiong has been an important oriental crude drug and cultivated for a long time in Korea. Ligusticum chuanxiong has been vegetatively propagating crop without seed due to its sterility and would be an allodiploid derived from the hybridization of two allied species. Generally, vegetative propagation is more costly per unit propagule than sexual(seedling) propagation. This study was conducted to find out the techniques of mass propagation by stem cutting for reduced seedling cost. When cutted on August 30 with 1st to 2nd internode, its highest rooting percentage was 81 percent. Rhizome yield of plants cutted in 50 percent on September 1 decreased to 9 percent less than control (rhizome propagation). Rooting percentage of rooted cutting plants after field planting on October 25 was the highest being 87 percent. Rhizome yield with planting appeared 127 and 120kg/10a on September 25 and October 25, respectively.

This study was carried out to examine the effect of polyethylene film color and removing time of the mulching film in yacon (Polymnia sonchiiolia Poepp. & Endl.). The plant height on nonmulching was smaller about 10 cm or larger with 112cm than on other mulches ranged with
cm at harvesting, and other characters examined were similar to that of plant height. The weight of tuberous root per plant was heavier on mulches ranged with
kg than on non-mulching with 0.61 kg. Among the kind of mulches, plant height was the tallest with 139 cm in combination and declined in order of transparent, green and black polyethylene films. Yields among colored polyethylene films were the heaviest with 0.91 kg per plant in combination, 0.88 kg in black and 0.84 kg in green. In growth and yield full mulching untill harvesting was more effective than the other removed mulching treatments. It was effected on growth promotion at early growth stage, soil temperature and water preservation.

Seed coating and pelleting techniques have been used in many crops to improve the germination vigor of tiny and light seeds. Cultivated Chinese-foxglove (Rehmannia glutlnosa) has been infected by various types of virus derived from vagetative propagation of rootstock. Seed characteristics and alginate-coated seed germination rate have been investigated to get basic information for healthy seedling production through seed propagation. Chinese-foxglove showed different numbers of seeds per pod from 61 in Seocheon local to 207 in Jiwhang 1 and 1,000grain weight also varied from 70mg of Seocheon local to 130mg of Jiwhang 1. Seeds of Chinese-foxglove has dormancy because that seed collected last year more stimulated than that of this year at germination test. Optimum alginate concentration for pellected seeds germination was 2%.

This study was conducted to obtain the information on dry matter productivity in Angelica gigas Nakai for establishing the cultivation method. Cultivation methods such as direct seeding on Mar. 31, Apr. 15 and Apr. 30, and transplanting of
, 9, 12 months old seedling were investigated. There were similar tendencies in changes of agronomic characters for all cultivation methods. Dry weight started to increase from 120 DAS. Direct seedling showed vigorous growth for aerial part, whereas transplanting showed better underground part. The quadratic polynomial was suitable to dry weight of root after 120 DAS (or DAT) .Short growing time had higher RGR and NAR independent of cultivation method but Direct seeding on Mar. 31 and transplanting of 9 months old seedling had the highest CGRs. LAI was positively correlated with CGR, and CGR had the highest value as
when LAI was 1.97. RGR and NAR increased as mean temperature was increased and showed the highest value around . The highest net production of leaf and petiole was obtained at 20 and
