Thirteen-day-old maize (Zea mays L.) plants were exposed hydroponically to sulfur (S)-deprivation and their nutritional status was monitored for ten days. Sulfur (S) -deprivation altered the allocation of nutrients between roots and shoots in a differential manner and the effect was approached in terms of a power function. The experimental curvature was analyzed through the value of the exponent of the function and two formulations of the approach were tested through regression analysis. In the shoot, the impact of the S-deprivation relative to that on dry mass was: calcium (Ca) (45.3%) > nitrate (NO3) (18.9%) > magnesium (Mg) (17.2%) > manganese (Mn) (14.1%) > water (W) = phosphorus (P) = potassium (K) = iron (Fe) = copper (Cu) > nitrogen (N) (-4.3%) > ammonium (NH4) (-4.7%) > zinc (Zn) (-12%) > boron (B) (-21.4%) > S (-75.2%). In the root, the relative impact was: N = K = Ca = Zn = B > P (-12.7%) > NO3 (-14.7%) > NH4 (-18.4%) > W (-27.8%) > Mn (-34.4%) > Mg (-37.5%) > Fe = Cu (-40.5%) > S (-126.6%). Both models produced the same conclusions.© Taylor & Francis Group, LLC. |
