The highestyielding cultivar was CF Momotaro J, which gave 20kg m^-2 under year-round cultivation. High-yielding environmental controls must be introduced into Japan to give the high tomato yields seen as in the Netherlands. Under low-truss nutrient film technique (short-term cultivation), root activity was significantly higher under high-yielding conditions than that under conventional conditions, but the correlation between yield and bleeding rate on each cultivars was not so high. These results suggest that the contribution of root activity to yield in short-term cultivation was lower than in long-term cultivation on the previous report. Therefore, this suggests that an increase in the amount of matter assimilated is the primary factor associated with high yield in shortterm cultivation.}, pages = {75--80}, title = {多収環境における NFT 低段栽培トマトの収量と根系の比較解析}, volume = {12}, year = {2013}, yomi = {ナカノ, アキマサ and カネコ, ソウ and ヤスバ, ケンイチロウ and ヒガシデ, タダヒサ and スズキ, カツミ and キムラ, サトル and タムラ, ショウゴ} }
