This study was investigated to find out the optimum rhizome size of ginger characteristics and yield at two planting densities. Seventy five gram of rhizome gave best performance for plant height and yield with comparison with the other sizes at two planting densities. Among 25g, 50g and 75g of ginger rhizome size were not significantly different in plant height and yield at 30×30cm planting density. But, 25g of rhizome size is economically recommended at 30×30cm planting densities.

This study was conducted to determine the inheritance to bacterial leaf blight in rice. Varieties used in the study were IR1544-349-2, IR1698-237-2, IR1529-680-3, IR28, IR29, RP663-337-7-8-4-1-1, RP291-20, 62-595 and Kele. The isolate of bacteial leaf blight used was 71-23, 76-1 of Xanthomonas oryzae. F_1s were obtained from crosses between resistant and susceptible varieties. Field observation was made from the Parents, F_1s and F_2 sagregating population. The result is summaryzed as fallow: 1) The resistance to the bacterial leaf blight (71-23) derived from cultivars IR1529-680-3, IR28, IR29, RP663-337-7-8-4-1-1, RP291-20 and 62-595 was controlled by a single dominant gene. 2) The resistance to the bacterial leaf blight (71-23) derived from cultivars IR1545-339-2, IR1544-340, IR1698-237-2 and Kele was controlled by a single recessive gene. 3) The resistance to the bacterial leaf blight (76-1) derived from cultivars IR1545-339-2, IR1544-340, IR 1698-237-2 was controlled by a single dominant gene. 4) Degree of resistance to the bacterial leaf blight and genetic type were different depending on isolates within the same resistant cultivar. 5) There was no relation between resistance to the bacterial leaf blight and heading days.

This experiment was carried out to define the effects of application amounts of the chemical fertilizers on plant growth and yield of the ginger. The results obtained are summarized as follows. Plant height of the ginger was 45.3 cm at lower level of fertilizer, 52.6 cm at recommended level, and 49.4 cm at higher level. Leaf area, stem number, and stem diameter were more significantly increased at higher level of fertilization compared to recommended rate. Dry weight of shoots and rhizomes were significantly increased with the increase of fertilization level. Stem number, stem diameter, leaf area, dry weight of shoots, and fresh weight of rhizomes were positively correlated with the amounts of fertilizer applied. Yield of rhizomes were 1, 653 kg at lower level of fertilizer, 2,248 kg at recommended level and 2,428 kg at higher level, respectively. Ginger yield showed 7.4% higher at higher level of fertilization compared to recommended rate.

Antifungal Activity of the Methanol Extract of Myristica malabarica Fruit Rinds and the Active Ingredients Malabaricones Against Phytopathogenic Fungi

Choi, Nam-Hee,Choi, Gyung-Ja,Jang, Kyoung-Soo,Choi, Yong-Ho,Lee, Sun-Og,Choi, Jae-Eul,Kim, Jin-Cheol The Korean Society of Plant Pathology 2008 Plant Pathology Journal Vol.24 No.3

In a search for plant extracts with in vivo antifungal activity for plant diseases, we found that the methanol extract of Myristica malabarica fruit rinds effectively suppressed the development of several plant diseases. The methanol extract exhibited potent 1-day protective activity against rice blast, tomato late blight, wheat leaf rust and red pepper anthracnose. It also showed 7-day and 4-day protective activities against the plant diseases. Three antifungal resorcinols were isolated from the methanol extract of M. malabarica fruit rinds and identified as malabaricones A(MA), B(MB), and C(MC). Inhibitory activity of the three resorcinols against mycelial growth of plant pathogenic fungi varied according to compound and target species. All three compounds effectively reduced the development of rice blast, wheat leaf rust and red pepper anthracnose. In addition, MC was highly active for reducing the development of tomato late blight. This is the first report on the antifungal activities of malabaricones against filamentous fungi.

Classification of blast resistance type of 129 Korean rice cultivars was carried out based on reaction pattern to 10 Japanese blast pathogen isolates (Pyricularia oryzae). The cultivars were divided into 11 groups based on the presumed resistance genes as follows; Pia type (19 cultivars), Pita-2 type (4), Pik type (3), Pib type (5), Piz type (11), Pik-s type (8), Pik and Pii type (4), Pia and Pita type (8), Pia and Pik type (6), Pita, Pik and Pii type (4) and no-grouping type (57). These results would provide important information to rice breeding for durable and broad resistance to rice blast.

To compare the gene order of the chloroplast genome among dicotyledonous plants, we constructed a physical map of chloroplast DNA (cpDNA) of Korean ginseng (Panax ginseng C.A. Meyer) with four restriction enzymes, Bam-HⅠ,HindⅢ, EcoRⅠ, and PstⅠ. The restriction enzyme recognition sites of the physical map were also confirmed by Southern hybridization of total ginseng cpDNA with homologous and heterologous probes. The cpDNA of Korean ginseng was determined as a circular molecule with a total size of about 154kb, which contain two inverted repeats of 23 kb each that disrupt the rest of the molecule into a large (90 kb) and a small single copy region (18 kb). The genome structure of korean ginseng cpDNA was similar in size and gene order to that of tobacco cpDNA. The cpDNA of Korean and American ginseng (P. quinquefolius) showed very similar restriction patterns.

Plant Cell Wall as an Inducer of Pectate Lyase of Erwinia rhapontici

Choi, Jae Eul,Han, Kwang Sup 충남대학교 생물공학연구소 1997 생물공학연구지 Vol.5 No.-

Pectate lyase(Pel)는 펙틴과 펙틴산을 분해하며, 기주식물의 감염에 관여한다. Erwinia rhapontici에 있어서 기주와 병원균의 병원성과의 상호관계를 구명하기 위하여 pectate lyase(Pel) 활성에 미치는 식물체 추출물과 세포벽의 효과를 검토하였다. 본 균은 glycerol이 포함된 minimal salts(MSG) 배지와 식물체 추출물이 첨가된 MSP 배지에서는 Pel 활성이 검출되지 않았다. 그러나 배추, 상추 잎, 감자 괴경, 셀러리 잎자루, 양파 인경, 당근 뿌리의 세포벽이 첨가된 MSP 배지에서는 Pel의 활성이 검출되었다. Pel을 유도하는 식물 인자는 불용성이고, 열처리에 불안전하였다. Pectate lyase (Pel) depolymerizes pectin and polygalacturonate and is thought to play a role in bacterial invasion into host plants. Effects of plant extracts and cell walls on the induction of Pel from Erwinia rhapontici strain 1 were wxamined to know hostparsite relationships associated with the pathogenicity of E. rhapontici. Pel activity was detected neither in minimal salts glycerol (MSG) medium nor in minimal salts polygalacturonate (MSP) medium containing plant extracts. Pel activity, however, was detected in MSP media amended with cell walls of Chinese cabbage, lettuce leaves, potato tubers, celery petioles, onion bulbs and carrot roots at the late stage of the bacterial culture. The Pel-inducing plant factors were water-insoluble and heat-labile.
