| Popis: | 「目 的」 生産方法の違いが、農産物の持つ抗酸化力にどのような影響を及ぼすのか、特に土壌養分の質の違いに着目し実験を行った。「方 法」 慣行農法と有用微生物群（EM）を活用した有機農法で別々に育てられた、自家採種の自然種の野菜（ダイコン）の抗酸化力・糖度・電気伝導度・可給態窒素を圃場にて栽培測定した。測定機器はウイスマー社フリーラジカル評価システムF.R.E.E(Free Radical Elective Evaluator)、アタゴ社製Brix糖度計およびHORIBA社製コンパクト電気伝導率計B-173を使用し、測定を実施した。統計処理は、Studentのt検定を行った。「結 果」 ダイコンにおける抗酸化力の平均値は、EM農法が493.05μmol /mlに対して慣行農法は440.44μmol /ml、一方糖度の平均値はEM農法が7.5Ｂrix%に対して慣行農法は7.1Ｂrix%であった。抗酸化力（0.01 Purpose: This study was conducted to examine how different farming methods can influence the levels of anti-oxidation and sugar contents in vegetables, specifically focusing on differences in the nutritional content of soil.Methods: Seeds of Daikon (White Radish, Raphanus sativus var. longipinnatus) were prepared. They were organically harvested and self-seeded. The seeds were separately grown in different plots with two different farming methods: Organic and Conventional. The organic farming method used in this research specifically refers to that using EM (Effective Microorganism) technology (EM organic farming hereafter). Daikon were grown in the different plots, and their changes were measured in the anti-oxidization, sugar content, electrical conductivity, and available nitrogen. A device called FREE, Free Radical Elective Evaluator, manufactured by Wismerll Co. Ltd., was used. B-173 Electric Conductivity Meter, manufactured by Horiba Ltd., and Brix Meter by Atago Co. Ltd. were also available for measuring the soil and vegetable contents. Student’s t-test was used to assess significance.Results: Average levels of anti-oxidation in Daikon were 493.05 μmol/mL with the EM organic farming, and 440.44 μmol/mL with the conventional farming. Regarding the Brix average, EM organic farming yielded a 7.5 brix%, and that for conventional farming was 7.1 brix%. EM organic farming led to higher levels of anti-oxidation and sugar contents than conventional farming (p |
