Abstract The genus Echinochloa constitutes some of the most prominent weed species found in rice ( Oryza sativa L.) production worldwide. taxonomy is complex due to its morphological variations. morpho-physiological diversity and taxonomic characteristics ecotypes infesting fields Texas are unknown. A total 54 collected during late-season field surveys 2015 2016 were characterized a common gard...

During plant-transpiration, water molecules having the lighter stable isotopes of oxygen and hydrogen evaporate and diffuse at a faster rate through the stomata than molecules having the heavier isotopes, which cause isotopic enrichment of leaf water. Although previous models have assumed that leaf water is well-mixed and isotopically uniform, non-uniform stomatal closure, promoting different e...

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% (co...
