Abstract

The aim of the present work has been to examine aspects of phosphate uptake during the day and the night under various conditions of culture solution. Phosphate uptake increased as the total salt concentration was raised from 25% to 100% strength of Enshishoho culture solution. Phosphate URN (rate of uptake at night to that in a whole day) was lowest with 25% strength of the solution and highest with 50% strength. Phosphate URN decreased, when phosphate concentration only was raised. It was also the case with calcium uptake and calcium concentration in the culture solution. Phosphate URN was not changed regardless of increase nor decrease in water or phosphate uptake, by feeding phosphate solution only, or addition of monovalent cations or NaCl to the culture solution. The present work has made it clear that phosphate URN is influenced solely by phosphate concentration, and not by water or phosphate uptake under various conditions of the culture solution.
