Implication

Methodological review demonstrates precise regulation of growth in solution-cultured plants, suggesting dynamic nutrient addition enables steady-state experimental control.

Key Points

To review the theoretical background and methodological techniques of using the relative addition rate of nutrients to achieve steady-state plant nutrition and growth.
Evaluated the shift from static nutrient concentrations to using culture solutions as dynamic carriers for repeated quantitative nutrient additions.
Assessed experimental variables including addition frequency tailored to plant growth rate, root-solution contact, and solution light exclusion.
Treating the relative addition rate as the driving variable allows quantitative control of nutrient delivery to sustain a steady-state relative uptake rate.
Achieving high experimental accuracy requires accounting for all essential nutrients, providing very frequent additions, maintaining darkness in the culture solution, and ensuring robust physical contact with roots.
