          말레이시아 농산물 수출입 동향

          김충수,이석영 충남대학교 농업과학연구소 2006 농업과학연구 Vol.33 No.2

          To strengthen the competitiveness of agricultural sector of the Korea, the direction of market trends on agriculture of the Malaysia was reviewed. The most dominating agricultural area in value is palm oil products, and forest products, sea products poultry products and rubber products is in order. The cultivated area of highest two top plants, oil palm and rubber, was about 4.4 million hectares in 2005, but it is decreasing year by year, Comparatively, rice field, pine apple and fruits tree cultivating area is increasing in tendency by the year. Among all the agricultural products, those items such as pork meat, poultry, egg were self-sufficient, rice, fruits, vegetables and sea products were about 70 to 80% self-sufficient, and beef meat, goat meat and milk were below 20% self-sufficient. Most of the grains, such as wheat, rice, barley, corn etc. and their processed food were imported. Also, temperate fruits such as apple, pear, and water cultivated as well as sprouting vegetables are imported. Ornamental products as cutting flowers and orchids are exported to mainly to the Singapore, but high quality temperate fruits and vegetables are imported from Australia. Oil palm exportation covers the balance of the other items imported and obtaining the foreign money as well in Malaysia.

          근류균(根瘤菌)(Rhizobium meliloti)의 접종(接種)이 Alfalfa의 근류형성(根瘤形成) 및 초기생육(初期生育)에 미치는 영향(影響)

          김충수,Kim, Choong Soo 충남대학교 농업과학연구소 1979 Korean Journal of Agricultural Science Vol.6 No.2

          This experiment was carried out to define the affinity of alfalfa varieties to nodule bacteria and the effects of nodule bacteria on the growth of alfalfa varieties. The results obtained are summarized as follows; 1. The ability of nodule formation on the roots of alfalfa was significantly different among the strains of nodule bacteria, Rhizobium meliloti SU 47 formed nodules on the roots of two alfalfa varieties, Luna and Von arnims altd bost. Nodules were not formed at the roots of all varieties by inoculation of Rhizobium meliloti M1 but a lot of nodules were formed at the roots of all varieties by inoculation of Rhizobium meliloti M14. 2. When the Rhizobium meliloti M14 was inoculated in the media, the largest numbers of nodules were formed on the roots of alfalfa cultivar Franks hangmeiler and the least numbers of nodules were formed on the roots of cultivar Elga. 3. The plant height and the dry matter weight of all alfalfa cultivars were significantly increased by inoculation of Rhizobium meliloti M14, and also those were increased by applying nitrogen, but when the alfalfa cultivars were grown on the media inoculated Rhizobium M1, the plant height and the dry matter weight of alfalfas were not increased and they were same as those grown on check media. 4. The significant correlation were not detected between the number of nodules formed on the, roots of alfalfa cultivars and the plant height or the dry matter weight of alfalfa cultivars. 몇가지 Alfalfa 품종(品種)의 근류균(根瘤菌)에 대(對)한 친화성(親和性) 및 접종효과(接種效果)를 구명(究明)코자 시험(試驗)하였던 바 결과(結果)를 요약(要約)하면 다음과 같다. 1. 접종균주간(接種菌株間)에는 근류형성성(根瘤形成性)에 현저(顯著)한 차이(差異)를 보였으며 Rhizobium meliloti SU47균주(菌株)는 Luna, Von arnims altd bost 등(等) 두 품종(品種)에만 근류(根瘤)를 형성(形成)하였으며 M1균주(菌株)는 전품종(全品種)에서 근류(根瘤)를 형성(形成)치 않았고 M14균주(菌株)는 전품종(全品種)에서 근류(根瘤)를 형성(形成)하였다. 2. 근류착생수(根瘤着生數)는 Franks hangmeiler 품종(品種)이 가장 많았고 그 다음이 Galilee 품종(品種)이었으며 Elga 품종(品種)이 가장 적었다. 3. 초장(草長) 및 지상부건물중(地上部乾物重)은 공시품종(供試品種) 모두 M14균주접종구(菌株接種區)가 가장 컸고 그 다음이 질소대조구(窒素對照區)였으며 M1접종구(接種區)와 대조구(對照區)에서 가장 작았고 근장(根長) 및 지하부건물중(地下部乾物重)은 품종간(種間)및 처리간(處理間)에 유의성(有意性)을 인정(認定)할 수 없었다. 4. 근류착생수(根瘤着生數)와 초장(草長) 및 근장(根長) 그리고 지상부건물중(地上部乾物重)과 근건물중(根乾物重)과는 상관관계(相關關係)를 인정(認定)할 수 없었다.

This experiment was conducted to select genotypes that were high-yielding and adapted to the soil and weather conditions in Korea, from 13 Fawn deri ved progenies which represented in the previous study. Comparisons were made in various leaf and plant characteristics, and forage productivities, between the 13 polycross progenies of high-yielding Fawn and control varieties including Fawn, Alta, and Kentucky 31. The results obtained were summarized as follow; Genetic differences between the polycross progeny group and the control group were recognized in leaf fresh weight but those between two groups in leaf dry weight were not observed. Leaf area of all derived progenies and control varieties were appeared to have individual genetic differences and, moreover, the leaf area of the polycross progeny group was larger than that of the control. Differences between polycross progeny group and control group in leaf width were not significant. However, leaf length exhibited significant differences among all polycross progenies, and control varieties between two groups, and among polycross progenies but no differences were observed among control varieties. Tiller number, plant height, and plant width of the polycross progeny group were larger than those of the control varieties when measured before and after harvest. Panicle length among all polycross progenies and control varieties showed minor differences. However, significant differences were found between the polycross progeny group and control group, as well as among the polycross progenies and control varieties within each group in culm length. Above characteritics in the leaf fresh and dry weight, area and length, plant width and height, and tiller number showed positive correlations with the forage yields, respectively. Forage yields of the polycross progenies were higher than those of the control varieties and the variation of the yields among the genotypes were great.

          참깨의 적정입모확보(適正立毛確保)를 위한 기초자료(基礎資料)를 얻고 저 청송등(等) 6개품종(個品種)에서 삭과착생부위별로 채취(採取)한 종자(種子)를 공용(供用)하여 발아(發芽) 및 초기생육(初期生育)을 조사(調査)하였던 바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. 파종기(播種期)를 지연(遲延)시킴에 따라 각품종(各品種)의 개화(開花)까지 일수(日數)는 현저(顯著)한 감소(減少)를 보였는데 파종기지연(播種期遲延)에 따르는 개화(開花)까지 일수(日數)의 감소정도(減少程度)는 품종간(品種間)에 현저(顯著)한 차이(差異)를 나타 내었다. 2. petri dish나 pot에서 공(共)히 IS103을 제외(除外)한 전공시품종(全供試品種)에서 하위절(下位節)에서 채취(採取)한 종자(種子)의 발아율(發芽率)이 하위절채취종자(下位節採取種子)의 발아율(發芽率) 보다 높았다. 3. IS103은 하위절(下位節)에서 채취(採取)한 종자(種子)의 발아율(發芽率)은 petri dish에서는 20%, pot에서는 75%의 발아율(發芽率)을 보였고 상위절채취종자(上位節採取種子)에서는 petri dish에서는 17.0% pot에서는 72.5%의 낮은 발아율(發芽率)을 보였다. 4. 발아세(發芽勢)에 있어서도 발아율(發芽率)과 같은 경향(傾向)으로 하위절채취종자(下位節採取種子)가 상위절채취종자(上位節採取種子)의 발아세(發芽勢)보다 높았으며, petri dish에서의 발아세(發芽勢)보다 pot에서의 발아세(發芽勢)가 현저(顯著)히 낮았다. 5. 초장(草長), 근장(根長), 엽장(葉長) 및 생체중등(生體重等)은 전공시품종(全供試品種)에서 하위절채취종자(下位節採取種子)가 상위절채취종자(上位節採取種子)보다 컸으나 종자입중(種子粒重)에 따르는 발아율(發芽率) 및 초기생육(初期生育)은 동일품종내(同一品種內)에서는 그 차이(差異)가 인정(認定)되나 품종간(品種間)에는 인정(認定)되지 않았다. To obtain the information on the germination and initial growth of the sesame, the seed of 6 sesame cultivars obtained from upper and lower position of plants were seeded and the results on the germination and initial growth were summarized as follows; 1. When the seeding time was delayed, the days to flower of all sesame cultivars were significantly decreased. And the shortening rate of days to flower by delaying seeding time showed significant differences among the sesame cultivars. 2. At all cultivars excluding IS 103, the germination percentage of the seeds obtained from lower position of sesame plant was significantly higher than those from upper position. 3. Germination percentage of IS 103 seeds from lower position of sesame plant was 20.0% at petri dish experiment and 75.0% at pot experiment and those from upper position of the stem was 17.0% at petri dish experiment and 72.5% at pot experiment, respectively. 4. The germination speed of all cultivars showed a same tendency as germination percentage, but the germination speed of cultivars at pot experiment was higher than those at petri dish experiment. 5. The sesame seedlings from lower position seed were increased in stem length, root length, leaf length and fresh weight than those from upper position seed. The germination percentage and the initial growth showed significant differences by the seed weight in same cultivar, however did not show any varietal differences.
