Korean Journal of Medicinal Crop Science, volume 5, issue 3, 1997, Pages 169~176
Gibberellin (GA) has been widely used to break seed dormancy for better stand establishment. The experiment was done to clarify the effect of
(concentration; period) and light quality (red; white; dark) after sowing on seed germination and radicle elongation of Campanulaceae (Platycodon grandiflorum; Codonopsis lanceolata; C. pilosula) to get an information on their field emergence. The germination test was carried out with 12 hours irradiation for 9 days after priming treatment. In the darkness, the mean germination rate of all the species was decreased in the order to P. grandiflorum, C. lanceolata, C. pilosula. Their mean germination rates and radicle lengths were increased with increased concentration to 0.1mM of
. Earlier germination rate was higher but later one was less in 4-day
treatment than in 1- or 2-day
treatment. Light treatment. especially red light given after
treatment. eliminated the
treatment effect. Red light done after
treatment nearly blocked the germination of P. grandiflorum and C. pilosula but delayed that of C. pilosula compared to the other light quality treatments having the similar rate. In addition. the radicle elongation of all three species affected by light quality treatment showed the same result as the germination rate.

Twenty-four major ecological and physiolosical characters of the 54 accessions of taro(Colocasia antiquorum) were observed in the growing seasons of 1995 and 1996 in
, Korea. The average days to emergence of the 54 accessions were 21.7 and the accession which had the shortest days to emergence was Kurye #2. Petiole color of most accessions was green, except
#1, Iri #1, Puan #1 and Taiwan #1 which had purple petioles. All the accessions had cormels except Taiwan #1 which had long runners without cormels. Average yield of the accessions was 3,719 kg/10a and total carmel weight, average carmel number, average carmel and average corm weight were 787g/plant, 39.2/plant, 20.3g/cormel, and 263.6g/plant, respectively. Accessions
#1 and Wanju #1 showed superiority in the three important characters, total carmel weight/plant, average carmel weight, and corm weight. Multivariate analysis for the 24 characters indicated that petiole color and carmel type had relatively higher coefficient of variation, 56.8 and 44.4 %, respectively. Fifty four taro accessions could be classified into 11 groups with D(
) value of 110 on the basis of phenotypical characteristics. Most accessions were inclued in Group II. The Group I in which Taiwan #1 was included was genetically the most distant from the other groups. Accessions with purple petioles were grouped into the three different subgroups in which green petiole accessions were not included, indicating high dissimilarity between the different petiole color accessions. All the accessions grouped into the Group VIII,
#1, Wanju #1, Wanju #3, and
#2, had higher bioogical yield. Some accessions collected from the same district showed a high dissimilarity by being classified into the different subgroups.

This study was carried out to investigate the effect of polyamines, salt strength. sucrose and gelling agents on the regeneration of plantlets by meristem culture of Aloe arborescens Mill. and Aloe vera L.. Shoot multiplication was more effective when 10mg/ l spermine in Aloe arborescens and 1mg/ l spermidine in Aloe vera added into MS medium than when other polyamines were treated into media. A quarter strength of MS medium was effective for rooting of shoots regenerated. Higher concentration of sucrose (45g/ l) was more effective for shoot regeneration. Addition of 4g/ l gelrite into the medium was effective for induction of multiple shoots from Aloe than that of agar or other concentrations of gelrite. When plantlets regenerated from meristem culture were transferred to pot. survival rate of plantlets was 80% on perlite and was 95% on vermiculite. respectively.

Yu, Hong-Seob ; Bang, Jin-Ki ; Kim, Young-Guk ; Lee, Seung-Tack ;
Korean Journal of Medicinal Crop Science, volume 5, issue 3, 1997, Pages 191~195
This study was conducted to obtain the basic information on setting up selection procedure using seedling characteristics in Angelica gigas Nakai lines. Morphological characteristics of the seedlings including height, leaf and petiole length among lines tested showed difference significantly, meaning that earlier selection was possible. Bolting rate at maturity ranged from 0.6 to 74.6% and root yield did from 350 to 3,893kg/ha. Root yield was increased in the lines with below 5% bolting rate. Heritabilities of petiole length, seedling height and leaf length in seedling stage bolting rate and root yield were high, while those of leaf length, root diameter and root length were relatively low. Bolting rate at maturity was positively correlated with seedling height, leaf length, leaf width, petiole length and number of leaves. A highly significant negative correlation was showed between root yield and seedling height, leaf length and width, petiole length, number of leaves, root length or bolting rate. From the above results the selection markers were found to be height, leaf length and petiole length in seedling stage.

To characterize active cells during microspore culture of Angelica gigas, flow cytometric and epifluorescent techniques were applied. The knowledge obtained from these types of studies will give us insight into early stage in plant development and may lead to the application of microspore-derived from haploid plants for breeding in recalcitrant species. Viability of cultured microspore differed depending on the developmental stages. Frequencies of active cells from tetrad, uni-nucleate, bi-nucleate and matured pollen were 12.8, 49.3, 42.3 and 31.7%, respectively. Alive microspores have luminescent the green fluorescence stained with FDA and blue fluorescence stained with DAPI.

Kwon, Byung-Sun ; Park, Gyu-Chul ;
Korean Journal of Medicinal Crop Science, volume 5, issue 3, 1997, Pages 202~205
This study was carried out to determine the effect of sowing time on the flowering, growth and yield of Scutellaria baicalensis Georg, which was collected from Yeochon district, cultivated after barley in the southern coastal areas of Korea. Emergence and flowering dates in the sowing time of June 1 were earlier than those of the other sowing times. In the sowing time of June 1, length and diameter of main stem, number of node per main stem, number of branch per plant and dry weight of stem leaves were greater than those of sowing times of June 10 and June 20. Yield components such as main stem length and diameter, main stem numbers, branches per plant, dry weight of stem leaves, main root length and thickness, number of large root and fine root per plant, and dry weight of root were the highest at the sowing time of June I as the yield of 71.3kg/10a. Optimum sowing time of Scutellaria baicalensis Georg cultivated after barley was June 1 in southern areas of korea.

The pathogenic fungi associated with blight of leaf and stem in peony were leaf spot (Alternaria sp.), powdery mildew (Erysiphe aquilegiae) and rust (Cronartium flaccidum). The infection of leaf spot and powdery mildew begins from late April to midMay and rust was infected in early June. Blight time of aerial part in peony started from late May and the ratio of blight on leaf and stem was more than 50% in late Aug. Yields of root by the incidence time of blight of leaf and stem were 69.1% in late June, 65.4% in late July and
% in August and September. The number of root of more than 10mm in root diameter blighted in late June and July was much lower than in August, but the paeoniflorin content in the former was much higher than the latter.

Peony is commonly used as roots that peeled and dried. But intact root contains higher medicinal constituents than peeled root (machine peeling). The yield of roots was also higher in intact roots. Use of intact root saved the labor time for peeling and 15% of root from yield loss by peeling. Paeoniflorin content was different with each zones of root. The content of Paeoniflorin was 5.11% in epidermis and 3.28% in cortex. When peeled peony roots were dried at hot air after briquet fire drying, root color was good for commercialization. But color of intact root was good at hot air drying without briquet fire drying. The required time for drying was longer in drying of intact roots than peeled roots drying.

The significant chemical components estimating the quality of green tea were compared and analyzed in the shoots of Korean native tea plants. The results are summarized as follows. The contents of total nitrogen in tea leaves were in range of
, and the tea plants grown wildly in Bosong Daewonsa, Hwasun Ssangbongsa, Shunchun Changchun-ri, Hadong Ssanggyesa. and the cultivated tea plants in Kangjin Jangwon Sanup had higher contents of total nitrogen. The contents of tannin ranged from 12.5 to 18.3%. The contents of tannin of Kuryoi Chonunsa (18.3%), Kangjin Baekryonsa (16.7%) and Naju Bulhoisa (16.4%) were higher than those of Yangkwang Chonma-ri (12.5%), Hampyong Yongam-ri (12.7%) and Yosu Udu-ri (12.8%). The contents of caffeine were in range of
. The contents of caffeine of Kwangju Shamae Dawon (3.11%), Kangjin Jangwon Sanup (2.94%) and Shunchun Changchun-ri(2.87%) were higher than those of Tamyang Yanggak-ri(2.21%), Yosu Udu-ri(2.23%) and Kuryoi Hwaomsa (2.23%). The contents of vit. C were in range of
. The contents of vit. C of Changsong Oshan-ri (167.9mg/100g), Shunchun Shongkwangsa (185.6mg/100g) and Yongkwang Chonma-ri (185.8mg/100g) were lower than those of Kwangju Shamae Dawon (291.5mg/100g), Kangjin Jangwon Sanup (271.8mg/100g) and Shunchun Changchun-ri (269.5mg/100g). The contents of chlorophyll were in range of
, and the mean contents were in range of 242.0mg/100g. The contents of total amino acids were in range of
. The content of total amino acid at Kangjin Jangwon Sanup was the highest as 2,500mg/100g, and that of Shunchon Shongkwangsa was the lowest as 1,888mg/100g. Results of this study suggest that the native tea plants naturally grown at Bosong Daewonsa, Hwasun Ssangbongsa, Shunchun Changchun-ri, Hadong Ssanggyesa, and the cultivated tea plants at Kangjin Jangwon Sanup show excellent quality in terms of abundance of total nitrogen and total amino acids, and less contents of tannin.

Korean Journal of Medicinal Crop Science, volume 5, issue 3, 1997, Pages 225~231
This study was conducted to evaluate the growth and yield by sowing times and spacing using machine seeder on Coix Lachryma-jobi L. var ma-yuen
. Adlay was seeded at four different dates (April 20, May 5, May 20 and June 5). Planting spaces were controlled by the seed roller of tractor drill seeder attached to tractor at three spacing (
). The results were summarized as follows. Required days to emergence and days to anthesis were shortened as sowing date was late. But days to maturity were prolonged when sowing date was late. The accumulated temperature increased such as required periods increased. In growth characteristics, culm length was significantly different at different sowing times. But all growth characteristics was not affected by different spacings. In yield components, 1,000 grain weight and ripening rate were significantly different at different sowing times, also the number of tillers and branches was significantly affected at different spacings. Grain yield/ha was significantly different at different sowing times. But it was not significantly different at different spacings. Thus, in order to improve the yield of adlay using drill seeder, if it is not frost, sowing should be done as early as possible. As a result, suitable sowing time was April 20 with spacing at
using machine seeder in Korea.

This experiment was conducted to determinate the optimum harvesting time of Carthami Flos and grain in safflower. In dry Carthami Flos yields harvested at different days after flowering, threre was no significant difference between 2 days and 4 days, however, yield harvested at 6 days was decreased significantly compared with 2 days after flowering. As the harvesting time were delayed, lightness (L') and redness (a') of dry Carthami Flos were decreased but yellowness (b') of that was increased. Color differences (
) of dry Carthami Flos between harvesting days after flowering were not visible between 4 days and 6 days but between those (4 days and 6 days) and 2 days were visible. As the result, the optimum harvesting time of Carthami Flos was 4 days after flowering. Grain yields and its components were affected by not harvesting Carthami Flos but grain harvesting time. Threre was no significant difference in number of grain per flower head, percentage of ripened grain between grain harvesting time. However, weight of 1000 grains and grain yields increased until 20 days after flowering. As a conclusion, the optimum harvesting time was 4 days after flowering for Carthami Flos and 20 days for grain regardless Carthami Flos harvesting time.

The experiment was conducted to find causes of rooting failure in divided crown of peony cultivation. The results were as follows : In farmer s fields, damage rate of rooting failure in divided crown of peony was 32% as non-sprouting 5.6%, withering after sprouting 20.7%, and wilting after sprouting 5.7%, repectively. Damage degree in farmer s fields was followed, above 70% by 4%, 41 to 70% by 17%, 11 to 40% by 45% per total field area, respectively. It was caused by rooting failure. Damage rate of rooting failure as affected by different planting time was 18.2% for planting in autumn, 42.9% for planting in spring, and damage in divided crown was higher than in seedling. As periods to planting were prolonged, growth and yield were larger poorly, treatment with seminal-root sterilization and soil insecticide showed good growth and rooting but untreated control was very poor. Main cause of rooting failure in divided crown of peony was disease, Cylindrocarpon sp. and low quality of seeds.

Cyperus rotundus has been grown for a long time in korea to be used as medicinal crop. This study was conducted to survey the production status and economic analysis in chief producing area of Cyperus rotundus in Koryong, Korea. The Koryong area where was the major production area of Cyperus rotundus was composed of 0.6hectare cultivation size per farm household and the processes like cultivation, processing, shipping were formed unitedly. The most general management type was labor-extensive one which use the Nakdong river basin or idle land effectively. The cultivation area have been decreased gradually because the price was very low so that the income per hectare was just 3,880 thousand won and productivity per hectare was just 6,280kg. Thus, production condition was very inferior, it needs some self-help to encourage the production because it has some possibility as only regional special product.
