Tropical spiderwort (Commelina benghalensis L.) increases growth under elevated atmospheric carbon dioxide.
Although considerable effort is being spent studying exotic plant pests, little consideration has been given as to how invasive plants might react to the increasing concentration of CO(2) in the atmosphere. Tropical spiderwort (Commelina benghalensis L.) is considered one the world's worst weeds and is becoming more of a problem in agricultural settings of the southeastern USA. Growth responses...
متن کاملInfluence of Seedling Age at Inoculation and Cultivar on the Pathogenicity of a Virus Causing Yellow Mosaic Disease of Commelina Benghalensis L. on Cowpea
A screenhouse experiment was conducted to evaluate the influence of seedling age at inoculation and cultivar on pathogenicity of the virus causing yellow mosaic disease of Commelina benghalensis L, a broad leaf weed, on cowpea. Three cowpea varieties namely Vita 5, IT84S2246D and Ife Brown were grown in pots and inoculated with sap extracted from leaves of C. benghalensis infected with yellow m...
متن کاملEffects of Bacillus thuringiensis on non-target herbivore and natural enemy assemblages in tropical irrigated rice.
Endotoxins from Bacillus thuringiensis (Bt) produced in transgenic pest-resistant Bt crops are generally not toxic to predatory and parasitic arthropods. However, elimination of Bt-susceptible prey and hosts in Bt crops could reduce predator and parasitoid abundance and thereby disrupt biological control of other herbivorous pests. Here we report results of a field study evaluating the effects ...

متن کاملSedative and anxiolytic effects of different fractions of the Commelina benghalensis Linn.
The present study was designed to investigate sedative and anxiolytic properties of the four different fractions (chloroform, pet ether, n-butanol and hydromethanol soluble fractions, coded as CFCB, PECB, NBCB and HMCB, respectively) of the aerial parts of Commelina benghalensis using rodent behavioral models, such as hole cross, open field and thiopental sodium induced sleeping time tests ...
