  • To develope a microbial pesticide for the control of mulberry longicorn beetle, Apriona germari, Beauveria spp. were isolated from the infected Apriona germari larvae. The morphology of Beauveria spp. was observed by phase contrast and scanning electron microscope. In addition, the Beauveria spp. isolated from Apriona germari were identified by the random amplification of polymorphic DNA using polymerase chain reaction. The results showed that the Beauveria spp., SFB-1A and SFB-3A, isolated from Apriona germari were identified with B. bassiana and B. brongniartii, respectively, suggesting that the random amplification of polymorphic DNA is effective for the identification of Beauveria spp.

  • 뽕나무 (Morus alba) 및 꾸지뽕나무(Cudrania tricuspidata) 잎으로부터 추출한 수용성 물질을 0.5% 콜레스테롤 투여 식이에 1%(w/w) 수준으로 첨가하여 각 조직에서의 지질 과산화물 생성정도를 나타내는 TBARS 측정법으로 항산화 활성을 검토하였다. 흰쥐의 체중 및 식이 섭취량은 실험군 간의 유의적인 차이는 없었다. 간장 및 뇌 조직 중량은 뽕잎 추출물군에서 증가하였다. 신장의 지질 과산화물 함량은 대조군에 비해서 뽕잎 추출물군에서 유의적으로 감소하였다. 뇌 및 심장의 지질 과산화에서 유의적으로 감소하였다. 뇌 및 심장의 지질 과산화물 함량은 대조군에 비교해서 꾸지뽕잎 추출물군에서 유의적으로 증가하였다. 간장 및 비장의 경우에는 각 실험군 간에 유의적인 차이가 없었다. 각 조직의 microsomes 분획으 지질 과산화물은 심장과 비장에서 뽕잎 및 꾸지뽕잎 추출물군에서 감소하였으나, 다른 조직에서는 현저한 차이가 없었다. 한편, 각 조직의 microsomes 분획을 얻어서 Fe2+/ascorbate로 지질 과산화물을 유도하기 위하여 37$^{\circ}C$에서 한시간 반응을 시킨 결과, 뽕잎 및 꾸지뽕잎 추출물군에서 약 절반 정도 감소하였으며, 상대적 증가량은 뇌조직 microsomes에서 현저하였다. 본 실험의 결과 신장조직 및 간장 microsome막 지질 과산화물 함량은 뽕잎 및 꾸지뽕잎 수용성 추출물에 의해 감소되었으며, 뇌 및 심장조직의 지질 과산화물 함량은 꾸지뽕잎 수용성 추출물에 의해 증가됨으로써 봉잎 추출물간의 차이를 나타내었다.

  • This research was conducted to determine the effect of the pre-treatment of mulberry charcoal on the salt tolerance response in Kentucky bluegrass 'Perfection'. As this results, 400 mM NaCl treatment reduced turf growth such a fresh and dry weight, and induced physiological damages like decreased chlorophyll content and increased electrolyte leakage. The pre-treatment of mulberry charcoal, however, mitigated those growth and physiological responses associated with NaCl stress, regardless of the concentrations of charcoal solution. Furthermore, it was observed that higher K ion concentration by mulberry charcoal pre-treatment reduced Na ion in shoot. This research suggests to be a possibility of planting turf grasses in reclaimed land or higher salt accumulated area using a mulberry charcoal treatment.

  • Isolation, indentification, bioassay and distribution of ice nucleation active(INA) bacteria were done on branch rot of mulberry which was severely developed after harvest of mulberry branches in autumn. Twelve isolates and two isolates out of thirty-six isolates had ice nucleation activity from -5$^{\circ}C$ to -1$0^{\circ}C$, and over -5$^{\circ}C$, respercively. Isolates which formed ice nucleation from -5$^{\circ}C$ to -1$0^{\circ}C$ were not inclined to injure tomato and corn seedlings. However, Two isolates, SE9316 and SE9338 which formed ice nucleation over -5$^{\circ}C$ injured mulberry, tomato and corn seedlings. SE9316 and SE9338 were identified as Pseudomonas syringae based on the morphological, cultural and biochemical characteristics. Populations of ice nucleation active bacteria, fluorecent pseudomonads, were higer in February and April, but they decreased in May. Populations decreased as they become distant from the center of the symptom. The bacterial populations of all sampling times and sites were higer than 105 cfu/g which was enough to induce frost injury.

  • Ethanol extract of barks, roots, stems, leaves and seeds of 49 species of plants were examined their growth inhibition by disk method on Listeria monocytogenes ATCC 19111, ATCC 19112, ATCC 19113, ATCC 19114 and ATCC 15313. The extracts exhibited comparatively strong growth inhibition were compared their activity with broth culture containing different concentration of the extracts. L. monocytogenes ATCC 19111 was inhibited by Siegesbeckia pubescens Makino and Morus alba Linne (Ma) extracts. L. monocytogenes ATCC 19112 and ATCC 19114 were inhibited by Ma extract. ATCC 19113 was inhibited by Sophora flavescens AITON and Ma extract. ATCC 15313 was inhibited by Foeniculum vulgare Gaertner, Prunella vulgaris Var lilacina Nakai and Ma extract. Ma extract showed comparatively good inhibition effect for 5 strains of L. monoytogenes. 500 ppm of Ma extract almost inhibited the growth of all L. monocytogenes tested.

  • Single-strand conformation polymorphism (SSCP) analysis of MD and JWB phytopalsma isolates which amplified PCR products using the R16F2n/R2 phytoplamsa universal primer pair were compared for variations of their nucleotide sequence. The MD and JWB phytoplasmas were clearly distinct each of the band patterns from about 1.2 kb PCR products. To clearly distinct of close SSCP band patterns, the MD and JWB phytoplasma PCR products were mixed and performed to detect their polymorphism. The SSCP band patterns show all of bands of MD and JWB on single lane and easily distinct their each band patterns. The PCR-SSCP analysis was possible to detect of 1.2 kb nucleotide sequence and near close band patterns were easily distinct by mixing two samples.

  • To study the cultural characteristics and wood rotting ability of the secondary mycellia of Armillaria mellea, it was cultivated on the various media. The optimal mycelial growth condition was 20~27 and pH 5.0~6.5 on PDB. A. mellea grew well on MEA, PDA and GP. Lactose and mannitol as carbon sources and glutamic acid as nitrogen sources were found to be effective as additives. A. mellea employed in this study have the characteristics of white rot types. Pine and oak wood were selected as candidates for sawdust substrate.

  • 1. This experiment was made for a comparable test of five different chemicals on control effects of mulberry die back disease from the autum of 1967 to that of 1968. These chemicals were EMP, PMF, lime sulfur, chlon, and PMA. 2. The experiment showed the EMP and PMF were the best chemicals among those for controling it, and the others no significance comparing with the control. 3. The best way was a twice sprang of 150$\ell$ EMP(1/1500 con.) per 10ar to the base of branches to the full extent through september and october.

  • On the purpose of exploiting cellulose resourse which is needed for artificial diet of silkworms, mulberry branch, eastern cotton wood branch, pitch pine pulp, poplar pulp, chaff, sawdust and rice straw were examined. Among the matters above mentioned. mulberry branch and pitch pine pulp were found to be replaceable as cellulose component in the artificial diet. By means of some chemical treatments, it is found that one of the extracted cellulose powder from mulberry branches is more useful in the larval growth.
