| During a 35-day growth cycle, N, P, and K uptake was determined by measuring changes in their contents in culture solutions. At harvest, plants were separated into the roots, base organs and shoot, and dried for tissue analysis for N, P, and K. The uptake rates of N, P, and K followed cyclical patterns that was related to shoot development and harvest, but were independent of the transpiration rate. Uptake of N declined from 5.6 mmol $plant^{-1}$ $day^{-1}$ just prior to the cycle initiation to 4.0 mmol $plant^{-1}$ $day^{-1}$ at day 15. Uptake rate steadily increased as flower stems reached maturity up to 10.3 mmol $plant^{-1}$ $day^{-1}$ day 35. Uptakes rates of P and K followed similar patterns of N uptake. Tissue concentrations of N and P steadily decreased since day 15. Content of K was the lowest at day 20 and steadily increased thereafter. In the root tissue, N and K contents were the lowest at day 15, increased to day 30, and then decreased at day 35. Tissue P content was just a reverse of those of N and K. |
