摘要：A cultivation behavior in high density cultivation of mung bean sprouts was investigated from the engineering viewpoint. The effect oxygen concentration on the growth rate was evaluated, because heterotrophic growth and secondary metabolism reactions were related to oxygen. The cart with controllable circuit for gas phase was used for high density cultivation. In a growing test of mung bean in high density and individual cultivations under various oxygen concentrations, courses of fresh weight, and whiteness index of seedling of mung bean sprouts were measured, and specific growth rate based on fresh weight were investigated. In high density cultivation, specific growth rate was faster than in individual cultivation, and differences in growth rate according to growth stage were observed with oxygen concentration. On low oxygen concentration whiteness index of the seedling raised. Therefore, it is assumed that oxygen concentration was so low that secondary metabolism reaction of brown substances in root of seedling was limited. These results suggest that growth and secondary metabolism reactions in high density cultivation could be regulated by controlling oxygen concentration in gas phase. In this study, we proposed that the concept of Controlled Atmosphere (CA) might be applied in plant cultivation as well as CA storage.
其他摘要：高密度栽培系における緑豆発芽野菜の栽培プロセス確立のため，酸素制御による緑豆の従属栄養生長反応および二次代謝反応への影響を評価した．高密度栽培系の試験には気相制御可能な台車を用いた．高密度栽培系および一個体栽培試験を実施し，酸素濃度条件の異なる栽培環境の重量およびもやしの根と茎の白度の測定と，一個体の重量基準の比生長速度を求めた．高密度栽培系では一個体栽培よりも，低酸素濃度における比生長速度が速い傾向があり，生産効率性が高くなった．また，酸素の低濃度制御により，根と茎の白度比が高くなったため，根の褐色物質生成反応が抑制されたと考えられた．以上の結果から，高密度栽培系において，酸素濃度の気相制御による生長反応と二次代謝反応の制御が可能であることが示された．本研究により，青果の鮮度保持に気相制御技術が利用されているControlled Atmosphere（CA）貯蔵のように，植物栽培でもCAの概念が応用できる可能性が示唆された．
