1. A study was performed on the relative growth of cucumber seedlings, Cucumis sativus L. var. "Kurume-ochiai No.2," grown in continuous artificial illumination, ca 6000 lux at plant height, at 30℃ throughout experiments, in the Phytotron, Kyushu University. 2. Seedlings grew up quite well and dry matter production on top and on root was measured. 3. Relationships between the growth of the whole plant (X) and that of the top (Y_t) and of the root (Y_r), respectively, were reproduced as the following linear regression equations excepting the very beginning of the seedling growth. Y_t=0.897X－16.2 Y_r=0.103X+16.2 4. Therefore, the top-root ratio P(X) could be expressed as follows: P(X)=0.897X－16.2
0.103X+16.2
1. 九州大学生物環境調節研究センターの人工照明室においてキュウリ(Cucumis sativus L. var. “Kurume-ochiai No.2”を6000lux連続照明下で育苗し,地上部および地下部における乾物重の増加を調べ,幼苗の相対生長について検討した. 2. 乾物重によつてあらわされた個体の生長(X)と地上部の生長(Y_Top)との関係および地下部の生長(Y_Root)との関係は,次の回帰直線によつて与えられた. Y_Top=0.897X－16.2 Y_Root=0.103X+16.2 3. したがつて,T/R比(P)はP=0.897X－16.2
