The Effect of Soil Conditioners on the Rutin Biosynthesis and the Yield of Buckwheat(Fagopyrum esculentum moench)

메밀의 rutin 생합성과 수량에 대한 토양개량제의 효과

This experiment was conducted to investigate the effects of soil conditioners, such as lime, borax, poultry waste sawdust manure (P.W.S.M) and mixed oil cakes (M.O.C), on the rutin biosynthesis and the yield of buckwheat. The content of phosphorus ($P_2O_5$) in buckwheat plants before flowering was higher at before flowering than that of flowering time at all plots. The content of nitrogen (N), potassium ($K_2O$), calcium (CaO) and magnesium (MgO) was lower at before flowering than those of flowering time at all plots. The contents of rutin in buckwheat plant at flowering time was higher than that at before flowering content of rutin in leaf was higher than that in stem. The contents of rutin in buckwheat plant was the highest at the plot treated with borax (B) compared to other plots. Correlation between rutin and amino acid was positive in buckwheat leaf, while it was negative in buckwheat stem. The yield of buckwheat was 21 percent higher at the plot treated with borax than the plot applied with the other three ingredients.

메밀의 rutin생합성과 수량에 대한 토양개량제의 효과를 구명 하기 위하여 전남농업기술원 시험포장에서 3요소, 3요소+석회, 3요소+붕사, 3요소+계분퇴비, 3요소+유박을 시용 하여 시험을 수행한 결과 메밀 식물체중의 인산 함량은 개화전 보다 개화기에 증가 하였고, 질소, 가리, 석회, 고토는 감소 하였다. 메밀중의 rutin은 줄기보다 잎에 다량함유되어 있으며 개화전보다 개화기에 많이 함유 하고 있었다. 잎중의 rutin과 아미노산 함량과는 정의 상관 이었으며, 줄기중의 아미노산 함량과는 부의 상관 이었다. 수량은 3요소+붕사 시용구에서 $1,092kg\;ha^{-1}$로 3요소 시용구 보다 21% 증수 하였다.
