申東永,李榮萬,金鶴鎭 韓國作物學會 1994 Korean journal of crop science Vol.39 No.2
본 연구는 항암식물로 효능이 인정되는 와송에 대한 기초적인 연구로 와송의 해부형태적 관찰, 대량증식을 위한 발아실험, 자생지의 토양분석 및 토양적응실험을 실시하였다. 와송의 잎은 끝에 가시가 있는 건생형이며, 엽세포엽록체는 유관속주위에 집중분포하고, 크고 엽록체를 갖지 않는 저수조직을 갖고 있으며 기공이 양면에 있는 양면기공엽이다. 줄기는 외사포위형유관속이며 중심주는 원기둥상이고 원생중심주이다. 뿌리는 다원형이며, 원생목부가 후생목부주위에 환상으로 배열되어 있고 외원형이다. 꽃의 구조는 꽃잎이 5개, 수술은 10개, 자방은 5개이며, 자방상위이고, 2심피 중축태좌이다. 와송종자 발아적온는 명상태 25℃ 에서 22.5%로 가장 좋았고, 휴면타파는 5℃ 에서 6~8일, GA3 100 ppm처리에서 가장 효과가 좋았다. 와송 자생지 토양분석결과 적정수준의 밭토양보다 유기물, 유효인산 석회 등은 높았고, 보비력, 치환성가리는 차이가 없었으며, 고토는 낮았다. 토양적응실험에서 돌가루 조합과 기와가루 조합에서 돌가루와 기와가루가 많이 첨가될수록 생육상태가 불량하였고, 배수가 양호한 처리구에서는 생육상태가 양호하였다. Wasong(Orostachys japonicus A. Berger) has been used as anti-cancer medicinal plants from ancient time. This experiment was conducted to obtain some fundamental informations concerning anatomical study, germination test, soil analysis of indigenious districks, adaptaion of soil for wasong. The leaf of wasong was xerotype with spine, mesophyl chloroplast is dense surrounded vascular bundle, with a many large water storage tissue without chloroplast, and was bifacial stomata leaf type. The stem of wasong was amphicribral vascular bundle, central cylinder was cylinder type and protostele. Root was polarch type, potoxylem of it's was arranged in ring shape of annulation and metaxylem. The structure of flower was cymose, was caylyx of 5 sepals, corolla of 5 petals, roecium of 10 stames, ovules of five, placentation parietal, ovary superior, axile placenta. The optimum temperature for seed germination was 25~circC under light and germination percentage was 22.5%. Dormancy breaking was effective for 6-8 days at 5~circC and at 100 ppm level of GA3 The soil analysis of wasong local districks, content of available P2O5 , Ca were higer than optimal level of upland and C.E.C., exchangeable k was not significantly different of that, but exchangeable magnesium was very low. The growth of wasong was affected draining regardless soil combination treatment.

Eight F_1 hybrids of pepper(Capsicum annuum L.) in combination with their eight parents were estimated for the degree of heterosis in fourteen characters. The high degree of heterosis over mean parents in F_1 hybrids was found in most of the characters such as days to flowering, fruit length, fruit width, fruit index, dried ratio. Especially plant length, number of branches, number of fruits, total yield were showed high degree of heterosis.
도라지(Platycodon grandiflorum DC.)의 種子 發芽에 미치는 水分과 ph, 播種用土 및 生長調節劑의 影響에 關한 硏究

This experiment was designed to examine the effects of water, pH, soil texture and growth hormone on the physiology of germination and superior sapling of bell flower plant (Platycodon grandiflorum DC). The results are summarized as follow. The soil water potential for the germination was in the range of 2.2 to 4.8bar with optimum at 2.2bar. Aerated water column(AWC), a device to promote the germination, greatly enhanced the rate and speed of germination. The preconditioning of seeds with low pH solution also promoted the germination. Approximately equal amount of clay and sand with additional 10% humus tended to promote germination. The effect of growth hormone on the rate and speed of germination showed that the GA was effective from 10 to 40ppm while 2.4-D at low concentration(0.05ppm). The combination of Gibberric acid and aerated water column system greatly enhanced germination.

Genetic differentiation of Trialeurodes vaporariorum (Westwood 1856) populations was examined using biochemical and allozyme analysis. For biochemical analysis, general esterase and glutathion‐S‐transferase were tested. Allozyme genetic variability in 11 populations of T. vaporariorum was investigated using five loci from four enzyme systems. Although there are large variations between populations, T. vaporariorum is grouped into two populations with geographic barriers, based on Nei's genetic distance in the Baekdudaegan Mountains. Within these two groups, low migration and linkage disequilibrium reveal that populations tend to be influenced by gene drift rather than uniform selection pressures. The effect of genetic drift is greater than the effect of uniform selection by insecticides or host plant resistance, which is suggested by the FST estimates in this study. Based on this basic research, more effective whitefly control programs could be built in the future.

- In order to find out the optimum fertilizer level and planting density of high yielding variety, Okayma#2, thisexperiment was conducted with 3 compositions of fertilizer levels and a different plant density at the experiment paddyfield of mat rush in Mokpo Experiment Station, National Institute of Crop Science, RDA. Okayma#2, mat rush varietywas grown under different fertilizer level and planting density with the highest yielding. Yield components such as stemlength, number of stem were highest at the plots with fertilizer level (㎏/10a), 80-20-40 and planting density, 20× 10㎝.Judging from the results reported above, at optimum fertilizer level and planting density of mat rush seemed to be 80-20-40㎏/10a fertilizer and 20㎝ row spacing and 10㎝ or 15㎝ planting spacing.Key words - Mat rush, Fertilizer Level, Plant Density, Yield, Quality골풀 시비량과 재식밀도 차이가 건경 수량과 품질에 미치는 영향- 305 -모든 처리에서 5월 20일에 경선단을 15㎝ 정도 절단하여 주었고, 도복방지망은 6월 25일에 설치하였다. 기타 재배법과 조사는 작물과학원 목포시험장 골풀 표준 재배법과 조사기준에 준하였고 이염토로서는 해남 백토를 사용하였다(임 등, 2006). 때에 골풀의 수량과 품질을 높이는 적합한시비량은 N-P 2O5-K 2O(㎏/10a)=80-20-40(㎏/10a), 재식밀도는 20×10㎝라고 생각되어지며 견제성 분석에서도 Table 8과같이 수익성이 높았다.경제성분석
도라지(Platycodon grandiflorum DC.)의 種子 發芽에 미치는 溫度, 光의 影響에 關한 硏究

The effects of tempterature, light on the physiology of germination of bell flower plant (Platycodon grandiflorum DC) were studied. The results are summarized as follow. The lower and upper temperature limit for germination was 10 and 35℃ within which the optimum was 20℃ . Germination rate was dependent on the presence or absence of light in relation to temperature applied. Germination was accerelated in the presence of light in the temperature was below the temperature. Light quality also affected germination rate in that the treatment with red and oranged cellophane film promoted when the temperature was below 20℃ . If the seeds were kept at 25℃ , the effective daylength was 14 hour while at 30℃ 24 hour.
