phytoextraction and phytostabilization potential of cadmium, chromium and nickel by populus alba and morus alba species
as a result of human activities, metal pollution has become one of the most serious environmental problems today. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. a pot experiment was conducted to compare the phytoextraction and phytostabilization potential of two plant species (populus alba and morus alba) for some eleme...
متن کاملCadmium phytoextraction potential of poplar clones (Populus spp.).
Biomass production, leaf number and area, photosynthetic and dark respiration rates, leaf concentration of photosynthetic pigments, nitrate reductase activity, as well as cadmium concentrations in leaves, stem, and roots were measured in poplar clones PE 4/68, B-229, 665, and 45/51. Plants were grown hydroponically under controlled conditions and treated with two different cadmium (Cd) concentr...
متن کاملMelia azedarach Extracts: A Potential Tool for Insect Pest Management
Plant derivatives possessing insect repellent and antifeedant properties could offer an alternative approach for managing crop pests and dealing with insect-transmitted diseases. This chapter summarizes results from studies on insecticidal effects of Melia azedarach extracts from Central Argentina. Extracts from different plant structures (green/ripe fruits, green/senescent leaves) and a variet...
متن کاملPotent limonoid insect antifeedant from Melia azedarach.
Systematic fractionation of a fruit extract from Argentine Melia azedarach L., which was monitored by an insect antifeedant bioassay, led to the isolation of meliartenin, a limonoid antifeedant, which existed as a mixture of two interchangeable isomers. At 4 microg/cm2 and 1 microg/cm2, the isomeric mixture was as active as azadirachtin in strongly inhibiting the larval feeding of Epilachna pae...
متن کاملphytoremediation potential of populus alba and morus alba for cadmium, chromuim and nickel absorption from polluted soil
metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 m...
