摘要

In greenhouse trials, Portulaca oleracea plants (a source of livestock fodder and a vegetable crop for human consumption) were irrigated with water at 3 salinity levels (ECi of 2.1, 15.2 or 28.5 dS m-1), and 0 or 2.3 mg Se litre-1, to assess the suitability of this crop for drainage water reuse systems. In the initial cuts, when plants were cut at ground level, shoot dry matter was reduced by 15-30% at 15.2 dS m-1 and by 80-90% at 28.5 dS m-1. Regrowth after cutting above the first node was vigorous and biomass from plants irrigated with 15.2 dS m-1 water was nearly double that from the 2 dS m-1 treatment. Se had a stimulatory effect on plant growth in some treatments but results were not consistent. No visual symptoms of Se toxicity were observed. It was concluded that P. oleracea is a good candidate for inclusion in saline drainage water reuse systems.
