 note = {汁液分析法を用いて, 各生育段階における, 硝酸態窒素濃度の異なる(2,4,8,12meq/ℓ)培養液で栽培したトマト2品種'桃太郎'と'TVR-2'の栄養生長及び各節位の葉身と葉柄内無機養分濃度の分析を行った。両品種ともに, 培養液硝酸態窒素濃度の違いによる第1花房果実緑熟期の地上部茎葉重の差異は, 第1花房着果期の第1花房下の葉の葉柄内硝酸態窒素濃度の差異と関連があった。各生育段階におけるカリウム, カルシウム, マグネシウム濃度の汁液分析値は, 培養液硝酸態窒素濃度の影響を大きく受けないことがわかった。ただし, 第1花房果実緑熟期のカルシウム濃度は, 葉身, 葉柄ともに, 培養液硝酸態窒素濃度の高い区で低くなる傾向が認められた。葉身に比べ, 葉柄内の硝酸態窒素濃度は, 早い生育段階から培養液の硝酸態窒素濃度の影響を受け, 差異が現れた。培養液硝酸態窒素濃度の変化に対する反応が大きいのは, トマト植物体の先端から7-9節位目の葉柄であると認められた。ただし, 第1花房果実緑熟期では, 上位葉の各花房間で葉柄内硝酸態窒素濃度の変動が大きいことが認められた。, The growth and concentration of elements in leaf blades and petioles of different leaf position and at different growth stage of two tomato varieties (MOMOTARO and TVR-2) cultured in the nutrient solution of four different nitrate concentration (2,4,8,12meq/ℓ) were determined by sap analysis. In both varieties, the top weight at mature-green fruit stage of the 1st cluster was related to nitrate concentration of the petiole directly under the 1st cluster at fruit setting stage of the 1st cluster. In all the growth stage, there were no large effect of nitrate concentration in the nutrient solution on the concentration of K, Ca and Mg in the leaf. High nitrate concentration in the nutrient solution tended to decrease the concentration of Ca in leaf blade and petiole at mature-green fruit stage of the 1st cluster. Nitrate concentration of petiole was influenced by nitrate concentration in the nutrient solution more quickly than that of leaf blade, the difference being noticeable at the early stage of growth. Compared with the nitrate concentration of petiole of lower leaves (below 1st cluster), that of young mature leaves (7-9 nodes from tip) were susceptible to the concentration of nitrate in nitrient solution. At the mature-green fruit stage of the 1st cluster, however, nitrate concentration in young leaves fluctuated.},
