高等植物に吸収された無機栄養素の行動(第3報) : なたね幼植物に吸収された燐の分布におよぼす日長処理の影響

The distribution of radiophosphorus absorbed in the young rape plants, under the photoperiodic treatment, was investigated. In this experiment, the one group was cultured with normal solution and the other group, with low level phosphorus content solution. Under the long day treatment, formation of flower primordia was observed only in normal solution group, but the relation between the flower initiation and the phosphorus translocation was obscure. Under the long day treatment, in both groups, accumulation of phosphorus was observed at the tops of plant, but, under the short day treatment, disturbance of phosphorus distribution occured. In the low level phosphorus group, specific activity of roots was lower than that of stem. The details of results were shown in Table 2 and Fig. 1.
