Description
<1>酸化剤を含んでなるダイコンの青変症の発症リスク評価剤である。
<2>酸化剤が過酸化水素であることを特徴とする上記<1>に記載のダイコンの青変症の発症リスク評価剤である。
<3>ダイコン種子、またはダイコン根部の切断切片、粉砕物、粉砕液もしくはそのろ液から選択される1つまたは2つ以上の評価対象に対して、酸化剤濃度が0.0001 wt%乃至10 wt%であることを特徴とする上記<1>または<2>に記載のダイコンの青変症の発症リスク評価剤である。
<4>(A)上記<1>乃至<3>のいずれか1つに記載のダイコンの青変症の発症リスク評価剤と、(B)該評価剤とダイコン種子、またはダイコン根部の切断切片、粉砕物、粉砕液もしくはそのろ液から選択される1つまたは2つ以上の評価対象とを混合し、該発症リスクを判別するための保持部と、を備えることを特徴とするダイコンの青変症の発症リスク評価キットである。
<5>ダイコン種子、またはダイコン根部の切断切片、粉砕物、粉砕液もしくはそのろ液から選択される1つまたは2つ以上の評価対象に、上記<1>乃至<3>のいずれか1つに記載のダイコンの青変症の発症リスク評価剤を添加することを特徴とするダイコンの青変症の発症リスク評価方法である。
ダイコンの青変症の発症頻度が高い品種(図1左)と青変症の発症頻度が低いまたは無い品種(図1右)の種子を8時間吸水させて膨潤させた後、種皮を除去し、20℃で3 wt%過酸化水素水を1.0 mL添加し、2時間反応後の青色の呈色を評価した。青変症の発症頻度が高い品種のみが青色に呈色したことから、本発明による、ダイコン種子を用いた青変症の発症リスク評価ができた。
ダイコンの青変症の発症頻度が高い品種(図2左)と青変症の発症頻度が低いまたは無い品種(図2右)の根部切片に、0℃から室温で0.1 wt%過酸化水素水を4 mL添加し、ダイコン切片表面を均一に過酸化水素溶液で覆い、5分後の青色の呈色を評価した。青変症の発症頻度が高い品種のみが青色に呈色したことから、本発明による、ダイコンの根部切片を用いた青変症の発症リスク評価ができた。
ダイコンの青変症の発症頻度が高い品種(図3左)と青変症の発症頻度が低いまたは無い品種(図3右)の根部の粉砕液1 mLに、0℃で1 wt%過酸化水素水を0.1 mL添加し、5分後の青色の呈色を評価した。青変症の発症頻度が高い品種のみが青色に呈色したことから、本発明による、ダイコンの根部の粉砕液を用いた青変症の発症リスク評価ができた。
ダイコンの青変症の発症頻度が高い品種(図4左)と青変症の発症頻度が低いまたは無い品種(図4右)の根部の粉砕液のろ液1 mLに、0℃で0.1 wt%過酸化水素水を0.1 mL添加し、5分後の青色の呈色を評価した。青変症の発症頻度が高い品種のみが青色に呈色したことから、本発明による、ダイコンの根部の粉砕液のろ液を用いた青変症の発症リスク評価ができた。
