Korean Journal of Medicinal Crop Science, volume 1, issue 2, 1993, Pages 97~103
Relationships between crown diameter divided into the small
, the medium
and the large seedling
by the size of crown diameter of Angelica gigas and topdressed nitrogen level of 0, 50, 70 and 100% were conducted to study on growth and yield of two year-planted A. gigas in Suwon. The larger of the crown diameter, the better of the dry weight of leaf and root of A. gigas. Growth of the plane was rapidly increased on June and August, but slowly increased on July and that of root was increased until October while decreasing the aerial stem growth from September. Lower top dressed nitrogen level in the larger seeding was greatly increased the bolting rate compared to the medium or small seedlings. Yields of dried root weight per 10a were 441kg for the large, 373kg for the medium, and 378kg for the small seedling, and weight of the higher nitrogen per 10a were more increased than that of the lower dressed nitrogen treatment.

Cho, Seon-Haeng ; Kim, Ki-June ;
Korean Journal of Medicinal Crop Science, volume 1, issue 2, 1993, Pages 104~108
This experiment was conducted to obtain the basic information for the increase ofgermination percent by the treatment of stratification, soaking and
in Angelica gigas Seeds caltivated in 1989. The germination percent was increased by 30% with stratification, and the effect of low temperature did not differ significantly. The optimum soaking temperature and periods were found to be 4days at
of water temperature. When exchanged water every day during soaking period, inhibitors were more extracted than non-exchange one. The exogenous application of
also increased germination percent about 20% campared with control, and the reasonable level was 2ppm in soaked seed and 5ppm in non-soaked seed.

Korean Journal of Medicinal Crop Science, volume 1, issue 2, 1993, Pages 109~114
This study was carried out to determine the optimum planting time for in vitromultiplied tuber of Pinellia ternata(Thunb.) Breit. The tubers were planted on April 20, May 20, June 20, July 20, August 20 and September 20 in 1990. Emergence ratios were 68 to 87% in any planting time except planting on July 20. The number of tubers per
at harvest in plantings on May 20 and June 20 were significantly higher with 1,110 and 1,021, respectively, while in plantings after July 20, those were drastically decreased. As compared with fresh yield of planting on April 20(352kg /10a), that of May 20 was 109% and June 20 was 103%, while those of after July 20 were from 41% to 19%. There was a highly positive correlation between dry tuber yield and the number of tubers per
. Tuber yields for commercial use(diameter over 7.1mm) were high in planting on May 20(322kg /10a) and on June 20(299kg /10a). It was suggested that optimum field planting time for in vitro multiplied tuber of Pinellia ternata(Thunb.) Breit was from May 20 to June May 20.

Park, Moon-Soo ; Park, Ho-Ki ; Kim, Tai-Soo ; Jang, Yeong-Seon ; Park, Keun-Yong ;
Korean Journal of Medicinal Crop Science, volume 1, issue 2, 1993, Pages 115~119
This study was carried out to determine optimum harvest time of in vitro multiplied tuber Pinellia ternata(Thunb.)Breit from 1990 to 1992. Tuber yield and its related traits were observed with four harvest times. Plant height was 7.2cm at 6 months and 19.3cm at 24 months after planting. The number of tubers per unit area was significantly increased with the passage of growing time after planting
, those were increased by 2.3 times in 6 months, 5.6 times in 12 months, 13.3 times in 18 months and 20.0 times in 24 months. The tuber sizes(length, width and weight) were highly enlarged during 12 to 18 months after planting compared with before or after this time. There were smaller tubers and lower tuber yields with shorter growing period, while large tubers above 7.1mm and higher yields with longer growing. It was suggested that the optimum harvest time was 18 months after planting, before over wintering rather than next year of spring, 24months after planting.
Studies on Improvement of Cultural Practices in Liriope platyphylla WANG et TANG III. Stimulation of Seed Germination and Effects of Seedling Age on Growth and Tuber Yield
Han, Jong-Hwan ; Yoon, Young-Hwang ; Kang, Dong-Ju ; Lee, Yu-Sik ;
Korean Journal of Medicinal Crop Science, volume 1, issue 2, 1993, Pages 120~124
Effect of eight different treatments to stimulate germination and of seedling ageson the growth and tuber yields of Liriope platyphlla was carried out in vitro(room temperature)and in vivo(field). Treatments, in vitro, of sulfuric acid(2%),
(100ppm), and stratification were most stimulated the germination of L.platyphylla. Among them the stratification was also the most effective for emergence in field and was shortened the days to germination in vitro and in vivo. Plant height and the number of leaves and tillers per plant in the sulfuric acid and the vinyl mulch treatments were the poorest, but those in other treatments were highered without any differences. Seeding of L.platyphylla was taken 66 days to emerge and the growth of that was more decreased than that of the seedlings. The younger seedling, the shorter the day of emergence of a new shoot. The olders were bloomed earlier and more increased the growth than the yongers and the divided seedlings, but the tuber yield was most increased in the 3 years seedling.
Study on the growth characteristics and production of leaf, stem and fruit in Lycium chinense
Chang, Yeong-Hee ; Park, Chun-Gun ; Kim, Dong-Hwi ; Youn, Kyu-Bok ;
Korean Journal of Medicinal Crop Science, volume 1, issue 2, 1993, Pages 125~128
This study carried out to know the growth characteristics and Co-production effect of leaf, newly developed stem and fruit by different harvest times. The dry matter yield of above growth part shown the highest at mid of July. Leaf dry matter, however, shown the highest at end of June and after that decreased drastically. The dry matter yield of newly developed stem increased gradually from early stage to harvest. Fruit set number of first branch was much higher than that of main stem and 2nd branch. The more leaf and newly developed stem harvest the less fruit yield obtained. When Co-production considered by economic yield, fruit yield with three times of leaf harvest shown the best production.

For the clonal proliferation of Gentiana scabra Bunge. which is one of the medicinaland ornamental plant, establishment multiplication of shoot through tissue culture technique and transplantation into soil were carried out. The shoot proliferation increased on the MS medium containing 0.5mg/l NAA and 0.5mg/l BAP. Optimum pH for shoot growth was pH 5.9, consequently MS medium supplemented with 2g/l activated charcoal was most effective for plant growth. There are two types of somaclonal variants, tall type was 63% and dwarf type was 37%.
Histological studies on in vitro Propagation of Pulsatilla koreana Nakai
Lee, Man-Sang ; Oh, Ki-Hong ;
Korean Journal of Medicinal Crop Science, volume 1, issue 2, 1993, Pages 137~157
This study was carried out to investigate the optimal condition for multiple propagation through leaf tissue culture and to apply anther culture techniques to Pulsatilla koreana Nakai breeding. Leaf and anther of Pulsatilla koreana Nakai were cultured on MS, MT, LS and
media supplemented with several growth regulators and nitrogen sources under various conditions. For callus induction and differentiation from the Pulsatilla koreana leaf segments were more effective in the combination of zeatin and auxin than auxin alone. The color of the callus was green when treated with IBA alone. Shoot differentiation was more effective when treated with zeatin than auxin alone, especially the best hormoal combination for shoot differentiation was zeatin 1.0mg/l +NAA 0.1mg/l, while 2,4-D inhibited shoot differentiation. The appeared rate of S pollen was 35% in vivo, while that of S pollen by low temperature
pretreatment for 4 days was increased by 53% and the optimum culture time for callus induction from anther was uni-nucleate stage.
basal medium supplemented with NAA 0.5mg/l and zeatin 1 mg/l was the most effective on callus formation and the best results of plant regeneration were obtained from combination of NAA 0.5mg/l and zeatin 0.5mg/l in anther culture.
as more effectives as the nitrogen source than
and the combination with zeatin 2.0mg /L was the best effective. The best combination for plant regeneration in callus induced from anther was
3800mg/l + zeatin 2.0mg/l. Ploidy level of anther-derived plants appeared 28% haploid, 47% diploid and the others were triploid, tetraploid and mixploid. In compare with E.S.T, M.D.H and P.X banding patterns were distinguished among callus, haploid and diploid plants in electrophoresis.
