The Inhibitory Effect of Grasshopper's Cyperus (Cyperus iria L.) on the Seedling Growth of Five Malaysian Rice Varieties.
Experiments were carried out in the laboratory and greenhouse to determine the growth inhibitory effects of Grassohopper's cyperus (Cyperus iria L.) on the seedlings of 5 Malaysian rice varieties namely MR211, MRQ74, MR220, MR84 and MR232. Three concentrations of the aqueous extract of the weed (12.5, 25.0 and 50.0 g/l) and weed debris (5, 10 and 20 g dry debris/1000 g soil) were used to test t...
متن کاملThe lethal effects of Cyperus iria on Aedes aegypti.
The sedge Cyperus iria, a common weed in rice, contains large amounts of the insect hormone (10R) juvenile hormone III (JH III). Given its widespread distribution in Asia and Africa, we examined the possibility that C. iria could be used as a safe, inexpensive, and readily available mosquito larvicide. Plants of varying ages were harvested and leaves tested for lethal effects on larvae of the y...
متن کاملPhytoremediation Potentiality of Cyperus Articulatus L
The phytoremediation potentiality of Cyperus articulatus naturally growing in industrial wastewater was tested. Nine heavy metals were selected for this purpose; As, Cd, Cr, Cu, Fe, Hg, Mn, Ni and Pb. Metal concentrations were measured using the atomic absorption. The accumulation rates of the studied heavy metals showed considerable variations in the accumulation abilities according to the pla...
متن کاملBiosynthetic pathway of insect juvenile hormone III in cell suspension cultures of the sedge Cyperus iria.
In most insect species, juvenile hormones regulate critical physiological processes such as metamorphosis and reproduction. In insects, these sesquiterpenoids are synthesized by retrocerebral endocrine organs, the corpora allata, via the classical mevalonate (MVA) pathway. One of these compounds, juvenile hormone III (JH III), has also been identified in the sedge Cyperus iria. In higher plants...
متن کاملPhytochemical observation and antibacterial activity of Cyperus esculentus L.
In the present study various extracts of Cyperus esculentus L. such as acetone, 50% ethanol, chloroform and petroleum ether were evaluated for their antibacterial activity against several human pathogens such as Escherichia coli, Staphylococcus aureus, Salmonella sp, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa and Citrobacter freundii, by using disc diffusion method. The act...
