Good growth could be get by a half strength of them, also. 2) Characteristic mineral deficiency symptoms were appeared in early stage of growth and the plants showed reduced growth obviously, when every one of N, P, K, Ca and minor elements (Fe, Mn, B) in the culture solution was absent. 3) Aeration was desirable for better growth of Japanese morning glory. But growth of non-aerated one under pot or container cultivation was also good. 4) The oxygen absorption of root decreased according as the concertration of nutrient solution became higher, so that of 10 strength solution was 60% as compared with that of standard solution. 5) The difference in oxygen absorption of root between standard solution and excess or deficit nutrient solution was not so significant except for NO_3-N absent solution in which oxygen absorption was rather decreased. 6) The absorption of oxygen by root, which was greatly affected by light condition increased in the afternoon and became highest at 4 p.m.. 7) The oxygen absorption of root was decreased by shading above-ground part and was particularly affected in the afternoon by the treatment of shading after morning."},
