Daily photosynthesis, water relations, and ion concentrations of euonymus irrigated with treated wastewater
Euonymus japonica Thunb. (euonymus) plants were submitted for 9 months to two irrigation treatments using water from different sources: a control (C) water with electrical conductivity (EC) less than 1.2 dS•m−1 and reclaimed wastewater (RW) with EC ≈4 dS•m−1. At the end of the experiment, no differe...
