pre-planting exposure stress on two-year-old, bare-root Corsican pine (Pinus nigra Arnold. ssp. laricio var. Corsicana) seedlings. Seedlings were lifted from a nursery and exposed to ambient conditions for periods of up to 192 h before being planted in minirhizotrons. Exposure decreased seedling water potential, CO2 assimilation rate, leaf conductance and new root elongation, and increased mort...

1. Twenty-eight male rats of initial age 27 d were fed on fortified-barley diets for 3 weeks. In all experimental diets, both crude protein (nitrogen x 6.25) and methionine:cystine were constant at 120.0 g/kg dry matter (DM) and 2:1 respectively. The basal diet contained 4.5 g methionine plus cystine/kg DM with L-methionine plus L-cystine (2:1, w/w) added in increments of 0.5 g/kg DM to a final...

A greenhouse experiment and a 2-yr field trial were conducted to compare various S sources for soybean [Glycine max (L.) Merr.] grown on an acid Oxisol in Brazil. In the greenhouse, included ammonium sulfate (AMS), monoammonium phosphate with ratio = 50:50 of AMS/elemental (ES) – (AMS + ES), ES bentonite containing 90% ES. All surface-applied at 0, 5, 10, 20, 40 mg kg–1. Separately, all incorpo...
