 note = {ホウレンソウ品種, 次郎丸およびキング・オブ・デンマークを水耕栽培し, 培養液濃度(園試処方の200∿12.5%)とpH(7.5∿5.0)が生育, 収量におよぼす影響を調査した。次郎丸では液濃度200∿50%, キング・オブ・デンマークでは100∿50%で収量および培養液からの養分吸収が多かった。両品種とも, 植物体のN, P, K含有率は液濃度の高い場合に高かった。Ca, Fe含有率は液濃度にあまり影響されず, Mg含有率は液濃度の高い場合に茎葉で高く, 根で低かった。収量の特に低かったpH5を除き, 液pHが生育, 収量, N, P, K吸収量におよぼす影響は小さかった。液pHが低い場合, Ca, Mg, Fe吸収量が少なかった。植物体の無機養分含有率は液pHによりほとんど影響されなかった。生体内硝酸塩含有率は液濃度50%以上の場合に著しく高くなった。液pH6.5前後の場合に最も低く, その他のpHではやや高かった。, Spinach cvs Jiromaru and King of Denmark were watercultured with the modified Hoagland soln of varying concn ranging 12.5 through 200%, or of varying pH ranging 5.0 through 7.5,and the growth and the yield were determined. Soln concns of 50-200 and 50-100% resulted in high yield and nutrient uptake of Jiromaru and King of Denmark, respectively. For both cvs, N, P and K contents of the plant parts were high with high soln concns. Ca and Fe contents did not respond to soln concn. Mg content was high in the top and low in the root, with high soln concns. Soln pH did not affect growth nor yield significantly, except for pH 5.0 with which yield was poor. While N, P and K uptake was not affected by soln pH, Ca, Mg and Fe uptake was restricted by low soln pH. It did not affect mineral contents of the plant parts appreciably. Nitrate content of the leaf was considerably high with soln concns above 50%, in contrast to the low content with soln concn below 25%. It was lowest with soln pH around 6.5,but higher with other soln pH.},
