Research Abstract

Water and elemental uptake movement was analyzed using radioisotopes. In the case of water, using O-15 labeled water, which half-life is only 2 min., tremendous amount of water leakage and re-entry from xylem vessels was demonstrated. A new imaging system to analyze real-time movement of nutrient elements was developed. The water storage mechanism of a cowpea plant was studied.
