herbaceous stem-tip cuttings, the concentration declines resulting from leaching of nutrients and the dilution effect, whereas mineral nutrient content in tissues decline from leaching ( Blazich, 1988 ; Svenson and Davies, 1995 ). As a result, the mineral
Mills, 2014 ). However, if more plants or leaf tissue were sampled, then a dilution effect may have occurred, indicating that leaf tissue Fe concentrations are actually lower and within a narrower range than the ranges reported here. However, Fe toxicity

cultivars had larger fruit weight ( Table 4 ) and perhaps higher fruit water content than many other cultivars, leading to a lower SSC value due to a dilution effect. However, ‘PF24–007’ peach had large size and low SSC but had good flavor. Also, cultivars

plants grown in the net houses may be ascribed to a dilution effect mainly due to the biomass increase as reported by Marschner (1995) . The Na and Cl concentrations were unchanged under different types of shelter, suggesting that Cl and Na uptake were
