  • 타가수정작물인 옥수수, 진주조, 메밀의 약 또는 조직배양기술의 향상을 위한 유전자형 및 문제점들을 찾아내어 개선하기 위하여 1988년 작물시험장 약 및 조직배양 연구실에서 실시한 주요연구결과를 요약하면 다음과 같다. 1. 옥수수 약배양에서 FR1141/FR16 교잡종이 N6배지에서, Fla 2BT 73/S 6013 교잡종은 5$^{\circ}C$에서 7일간 저온전처리를 한 후 MS배지에 치상하였을 때 callus가 형성되었으나 27 공시 교잡종의 전체 37,450 약중에서 단지 두 개만이 callus가 형성되었다. 2. 옥수수 수원 19호의 미숙배를 MS 배지에 치상하였을 때 모두 callus가 형성되었으며 이 callus로부터 녹색체 분화율은 8.6%이었다. 3. 옥수수 수원 99호 등 20품종의 미숙웅수배양에서는 FR1141/FR16, B68/A116N//KS15, KS16/KS17, Ga209/DN578, SDB126/Ga209 교잡종 등에서 callus 형성율이 비교적 높았다. 4. 진주조$\times$Napier grass 종간교잡종의 조기배양에서 간의 조기ㅐ양에 적합한 절간신장부위의 절편크기가 2.5~4.0mm 이었고 callus 형성율이 50~100%로 비교적 높았다. 5. 메밀 신농 1호 식물체 분화율은 27%이었다. Epicotyl에서 유도한 callus에서 1개 식물체가 분화하였다. 6. 타가수정작물인 옥수수, 진주조, 메밀의 유전자형$\times$배지 및 환경 상호작용이 있어 유전자형에 따라서 약 및 조기배양반응이 크게 달랐다.

  • A three year's field experiment was carried out on newly reclaimed tidal saline soils to evaluate the salt tolerance and growht characteristics, and their relationship to dry matter production and nutrient quality of main selected pasture species. Nine temperate grasses (14 varieties) and two forage crops (sorghum and pearl millet) were grown under different mulching treatments with medium sand and red-yellow soils (fine loamy materials of Typic Hapludults) from 1986 to 1988. Tall wheatgrass, tall fescue, reed canarygrass and alfalfa showed a good tolerance to soil salinity, especially tall wheatgrass (cv. Alkar) produced 19.6 ton/ha dry matter yield annualy under mulching treatment with medium sand depth in lcm. Pearl millet (cv. Gahi-3) was also evaluated as a salt tolerable forage species. Under salt stress in newly reclaimed tidal lands, plant showed a decrease in the assimirable leaf area (LA) as well as specific leaf area (SP. LA) and a low leaf weight ratio(LWR), and it resulted in a low concentration of crude protein and low digestible dry matter contents. Absorption of macro and micro elements in the plant on tidal lands was increased markedly.

  • Coarse grain crops including maize, sorghum, buckwheat, fox-tail millet, pearl millet, proso millet and barnyard millet have been used as health food, feed and industrial materials in Korea for a long time. Korean ancestors thought and treated them as the very important good crops for human health and the crops have served as a dish made with all the grains, particularly in January 15 of the lunar month in korea because the grains make the five viscera of heart, liver, spleen, lungs and kidneys and the six entrails of gall bladder, stomach, small and large intestines, the paunch, the bladder, and the bowels strong and build healthy body. Thus, the objectives of the paper were to review and summarize the results obtained from the quality breeding and functional researches worldwide on nutrition, utilization and medical action of the coarse grain crops. Maize grain, fresh ear and green fodder yields have increased since 1960s in Korea. Agronomic traits improvements also occurred for cold tolerance, disease and insect resistance, resistance to barrenness, resistance to loding, pollen production, grain and seed yields, and eating quality. For buckwheat, improved summer buckwheat varieties produced more rutin for vegetable and grain than autumn varieties in Korea

  • Stromatal fruiting bodies of Cordyceps cardinalis were successfully produced in cereals. Brown rice, German millet and standard millet produced the longest-length of stromata, followed by Chinese pearl barley, Indian millet, black rice and standard barley. Oatmeal produced the shortest-length of fruiting bodies. Supplementation of pupa and larva to the grains resulted in a slightly enhanced production of fruiting bodies; pupa showing better production than larva. 50~60 g of brown rice and 10~20 g of pupa mixed with 50~60 mL of water in 1,000 mL polypropylene (PP) bottle was found to be optimum for fruiting body production. Liquid inoculation of 15~20 mL per PP bottle produced best fruiting bodies. The optimal temperature for the formation of fruiting bodies was $25^{\circ}C$, under conditions of continuous light. Few fruiting bodies were produced under the condition of complete darkness, and the fresh weight was considerable low, compared to that of light condition.
