-temperature treatment (356 vs. 256 μmol/root for JR and 428 vs. 369 μmol/root for SQ) suggesting that the increase in GSL concentrations resulting from high temperatures was not strictly the result of a dilution effect. Cultivars and tissues varied in individual

concentrations in new stems of 16.8-UF and 33.6-UF is a dilution effect of biomass on the amount of N in the stem. Green ash trees fertilized with higher N rates from UF in 2005 were more active and had a higher demand for C from reserves in old stems earlier in

( Römheld, 2012 ). In addition, the decreased foliar concentrations of N and Ca with increasing organic fertilization rates suggest the presence of a dilution effect associated with the increased plant growth ( Fig. 2A and B ). Foliar concentrations of N, K

:1:2, the elevated foliar P concentration at 4:1:2 may be indicating luxury consumption. As N concentration increased in the nutrient solution, foliar K, Ca, and Mg concentrations decreased most likely as a result of a dilution effect because plants were

result in a discrepancy in the calculated pigment concentrations based on either the FM or DM calculations and has been attributed to a dilution effect ( Lefsrud et al., 2006 , 2007 ). Karathanos (1999) and Stegen et al. (1998) reported decreases

-Pérez, 2013 ). The decline in SSC with increased shade level may be a result of dilution effect caused by a possible increased fruit and whole-plant water status as a result of decreased plant and fruit transpiration under shaded conditions. Red bell pepper

a dilution of the nutrient concentration due to the greater SDM observed under both LED and HPS SL. This dilution effect was suggested by Kuehny et al. (1991) after observing decreased foliar concentrations of nutrients under increased irradiance

of both phosphorus and boron in leaves ( Fig. 3C–D ), although both are still within the satisfactory range considered for the cultivar. This might have resulted from dilution effect resulting from increased tree growth at higher N supply, but clearly

by ≈5% to 8% with increasing shade density, solely as a result of the dilution effect of starch on dry matter. Only in the case of leaf nitrogen in 2004 was the increase greater than expected as a result of the effect of starch dilution. Petiole
