  • 메밀(Fagopyrum esculentum Moench)은 마디풀과(Polygonaceae) 메밀속 (Fagopyrum)으로 약 20종이 있으며, 전 세계 인류 역사와 함께해 왔으며, 오랫동안 사랑을 받아 온 작물이다. 메밀 생태형 분류는 늦게 파종할수록 종실 수량이 떨어지는 여름메밀, 반대로 늦게 파종할수록 종실 수량이 증가하는 가을메밀과 중간형 메밀이 있다. 여름메밀 대표품종은 양절메밀, 양절메밀2호가 있다. '양절메밀'은 춘파·하파 재배가 가능한 여름메밀 품종으로, 1994년 육성되어 장려 품종으로 결정되었다. '양절메밀'의 특성은 유한생육 초형으로, 조숙·단간·다수성 이며, 꽃색은 흰색이며 종자는 흑색이다. 성숙일수는 60-64일로 짧으며, 성숙 후에도 탈립이 강하고, 경장은 단간으로, 도복에 강한 편이다. 그 후 수량성이 증가된 '양절메밀 2호'가 육성되었다. 양절메밀2호는 대립종자로 종자가 흑갈색이며 천립중도 29.5g으로 양절메밀보다 무겁다. 가을메밀로는 대산메밀, 다원 및 순백이 육성되었다. 싹용인 '대산메밀'은 줄기가 연홍색이고 종자가 갈색이었다. '대산메밀'은 가을메밀 품종으로 가을 재배에 적합하다. 경장은 중장간종이며, 생육 일수는 양절메밀보다 약간 늦은 중생종이다. 메밀싹 수율이 높아 새싹 재배에 적합한 것으로 나타났다.

  • 메밀은 마디풀과(polygonaceae)의 메밀속에 속하는 일년생 초본으로 야생종을 포함하여 20여 종이 확인되고 있다. 현재 재배되고 있는 메밀 재배종은 보통메밀(Fagopyrum esculentum Moench)과 쓴메밀(Fagopyrum tataricum Gaertn., 타타리메밀) 등 두 종이 주류를 이루고 있으며 우리나라에서는 보통메밀이 주로 재배되어 왔다. 본 연구는 농업유전자원센터에서 보유중인 보통메밀 341점과 쓴메밀 38점을 봄, 여름에 파종하여 특성조사를 수행하고 재배시기별 생육특성을 비교하기 위해 수행되었다. 봄, 여름 파종은 각각 2017년 4월 14일과 8월 17일에 전주 소재 농업유전자원센터 포장에 하였으며 줄기색, 엽색, 엽형, 개화기, 성숙기, 꽃색, 종피색, 종자모양, 주경절수, 총분지수, 백립중 등 11개 농업형질을 조사하였다. 봄 파종시 개화기는 대부분 5월 25일 전후였으며 성숙기는 6월 말부터 7월 중순까지 분포하였고 여름 파종시는 9월 15일 전후 개화하여 10월 말에 성숙하였다. 줄기색은 홍색의 비율이 높았고 엽색은 연녹색과 녹색이 대부분이었으며 엽형은 화살촉형이 90% 이상이었다. 꽃색은 흰색이 대부분이었지만 연녹색 자원도 40점 조사되었으며 종피색은 연갈색이 70%를 차지하였다. 종자 생산과 관련된 주경절수와 총분지수는 봄 파종과 여름 파종에서 많은 차이를 나타냈으며 봄 재배시 영양생장이 왕성하여 가을 재배보다 많은 주경절수와 총분지수가 조사되었다. 그러나 백립중에서는 여름 파종이 봄 파종보다 무거운 경향을 나타내어 주경절수, 총분지수와 백립중 간 부의 상관관계를 추론할 수 있었다. 일반메밀 유전자원을 국내 수집지별로 나누어 조사한 결과 주경절수와 총분지수는 봄, 여름 파종 모두에서 전남 수집자원이 가장 많았으며, 강원, 경남, 경북, 전북, 충북 수집자원과 유의성있는 차이를 나타내었다. 강원, 충북 수집자원은 제일 낮은 주경절수와 총분지수를 보였으나 백립중은 가장 높게 조사되었다.

  • In this study, the rutin contents in buckwheat and buckwheat foods were determined. Rutin in buckwheat and buckwheat foods was extracted with methanol and separated by High Performance Liquid Chromatography(HPLC) equipped with Lambda-Max Model 481 detector set at 355 nm using a ${\mu}$ Bondapak $C_{18}$ column and a 2.5% acetic acid:methanol:acetonitrile (35:5:10, v:v:v) solvent. There were differences in the rutin contents among the different species of buckwheat. The rutin contents in buckwheat groats were ranged from 8.84 mg to 24.77 mg/100g. The rutin contents in commercial buckwheat groats and flours were ranged from 15.04 mg to 20.92 mg/100g. The rutin contents in commercial dried buckwheat noodles, steamed buckwheat noodles, and buckwheat cookies were ranged from 1.76 mg to 10.84 mg/100g.

  • Buckwheat has been a popular favorite food crop in Korea for a long time. The objective of the study was to investigate the effects of climatic conditions and cultural methods on grain yields of summer buckwheat variety Sinnong 1 planted during the spring season in Suwon, Korea from 1989 to 1991. Frost minimum temperature of late April was -0.3$^{\circ}C$ in 1990 being very low as compared with 3.7$^{\circ}C$ of the normal year, and affected early growth of the seedlings emerging from the soil surface. In late May of 1990, the frost minimum temperature was 7.3$^{\circ}C$ being low as compared with 8.8$^{\circ}C$ of the normal year, and also induced cold injury to fertilization and grain filling. Total precipitation 374.5mm of mid and late June, 1990 provided serious damage to the grain filling and maturing buckwheat seeds and along with causing seed sprouting before harvest. However, the climates of 1989 and 1991 were very good for the growth and development of spring-sown buckwheats. When summer buckwheat cultivar Sinnong 1 was planted on April 20, 1989, its highest grain yields 268-292kg /10a were harvested from the plots of seeding rate 8kg /10a, drill seeding and polyethylene film mulching, and the mean grain yield of the plots was 238kg /10a in 1989, but 64.3kg in Suwon, and 40.2kg /10a in Muan in 1990. In 1991 maximum grain yield 277kg /10a was produced from the April 15 planted and vinyl-mulched plot, and 255kg /10a from the April 25 planted and non-mulched plot. Herbicide Alachlor-sprayed plots produced lower grain yields than no weed control and manual weeding plots. Mechanized drill-seeding saved 83~84% in planting hours as compared with manual broadcasting 21.6 hours /ha, and produced 9% more in grain yields from the two-season croppings of mechanized drill-seeding culture being 364kg /10a in total yields per year.

  • Fifty-five local collections of buck wheat, Fagopyrum esculentum, were investigated their ratios of long-styled (LS) and short-styled (SS) flowers, fertility, meiosis of megaspore and microspore mother cell, female and male gametogenesis, and egg apparatus in accordance with the sowing seasons (spring, summer), altitudes (20m, 50-100m, 300m), and parent style types (L, S). Also they were embryologically investigated the fertility, fertilizing phenomenon and proembryogenesis by the legitimate and illegitimate pollination. There were no differences in the ratios of long-styled and short-5tyled flowers along with altitudes, but more irregularness was observed in plain area than that in the mountaineous or coastal area. LS versus SS ratios by sowing seasons were significantly separated into 1 : 1 in the summer sowing (P 0.1), but they were irregularly separated in the spring sowing. The segregating ratios by parent style types showed more number of short-styled flower in the spring sowing, and were statistically seperated into 1 : 1 in the summer sowing (P 0.25), regardless to parent style types. In the artificial legitimate union, the seed setting rates of the summer sowing (59-61%) were much higher than those of the spring sowing (about 30%), but in the artificial illegitimate union the seed setting rates were only fructified about 0.8-1.8% in the spring sowing. The seed setting rates in accordance with flowering stages were larger in turn early, middle, late, in the summer sowing. The grain number and grain weight per plant of short-styled flower were more than those of long-styled one regardless to style types. The 1,000 grain weight of long-styled flower was heavier than that of short-styled one in large grain, but it was lighter than that of short-styled flower in small or medium grain. The percentage of normal female and male gametogenesis in the summer sowing were higher than those in the spring sowing. The ovule was atropous and two polar nuclei were a synkarion before flowering. The pollens germinated at 30 minuts after pollination and the pollen tube grew continually and penetrated into micropyle at 1.5-2 hours and the two male nuclei fertilized with egg nucleus at 3 -5 hours after pollination. Flertilizing times in summer were shorter than in autumn. The fertilized egg was divided in a small apical cell toward the interior of the embryo sac and a large basal cell toward the micropyle cell at 15-24 hours after pollination, and division times in summer were shorter than in autumn. The proembryo began the embryogenesis at 7-8 days and formed itself into the perfect embryo at 15 days after pollination.
