Gold Mine Wastewater Induced Morpho-physiological Alteration of Four Biodiesel Producing Species

This experiment aimed to determine the adaptability of four biodiesel-producing plants gold mine wastewater based on morpho-physiological properties. Four species namely jatropha (Jatropha curcas), castor bean (Ricinus communis), wild candlenut (Reutealis trisperma) and bead tree (Melia azedarach) were grown in water culture using Hoagland solution for 2 weeks then treated with mining at 0% (control), 25%, 50%, 75% (v/v) 3 weeks. Growth, anatomical physiological characteristics observed during treatment. The results showed that significantly decreased growth despite varied among species. Wastewater had significant effect leaves anatomy Jatropha but not others. It also induced increase malondialdehyde (MDA) content bean, bead-tree. Meanwhile, treatment chlorophyll all most bead-tree plant, relative (RWC) particularly plants. There was strong negative correlation between MDA decrease leaf RWC. Among species, (R. resistant morphological
