Eugenia uniflora L. is an important fruit tree native to tropical South America that adapts different habitats, thanks its metabolic diversity and ability adjust the leaf antioxidant metabolism. We hypothesized this would also enable E. avoid oxidative damage tolerate enhanced ozone (O3) concentrations have been registered in (sub)tropics. investigated whether carbohydrates, polyphenols antioxi...

Abstract Plants engage in many processes and relationships that appear to be wasteful of the high-energy compounds they produce through carbon fixation photosynthesis. For example, living trees keep leafless tree stumps alive ( i.e. respiring) support shaded understory by sharing carbohydrates root grafts or mycorrhizal fungal networks. exude a diverse array organic from their roots leaves, whi...

the concentration of three metals, zinc, copper and chromium in roots, rhizomes, stems and leaves of phragmites australis (common reed) and scirpus maritimus, and in the corresponding sediment and water samples from lia industrial area (qazvin, iran) were investigated to determine difference in distribution among plant organs. data were collected at during 1-year period. results showed that met...
