The effect of temporarily increasing the oxygen supply was studied in relation to the following factors : oxygen concentration, pH and electric conductivity of the nutrient solution, NO_3-N, P, K, Ca, Mg, Fe and water absorption, plant weight and size, root appearance, mineral composition of plant parts, yield and length of time required for fruit development. Effect of increased oxygen supply to the nutrient solution at one of the growth stages on growth, nutrient and water absorption and yield of the tomato was little, if any. The length of time required for fruit development, that is, the number of days from anthesis to harvest-ripeness of the indivisual fruit, was shortened when the oxygen supply was increased at the later stage of plant growth.}, pages = {31--39}, title = {蔬菜水耕栽培の実用化に関する研究 XIV : 生育段階別の溶存酸素供給量の差異がトマトの生育と収量におよぼす影響(農学部門)}, volume = {28}, year = {1976}, yomi = {ナミキ, タカカズ and フクシマ, ミチヒロ and ニシ, シンヤ and タカシマ, シロウ} }
