Soil in laboratory microcosm experiments was amended with dried and milled crop residue of onion (Allium cepa L. cv. Mission) or garlic (A. sativa L. cv. California Early). The amend ments, along with the additional factors of amendment concentration (0, 1 or 3% (w/w)) an soil temperature (23 or 39 8C), were evaluated with respect to germination of seeds of th weedy annual plants Echinochloa cr...

Background. Snails' species are associated with transmission parasitic disease as intermediate host. Biological control stands to be a better alternative to the chemical controls aimed against snails. The search of herbal preparations that do not produce any adverse effects in the non-target organisms and are easily biodegradable remains a top research issue for scientists associated with alter...

Solanum nigrum was found to proliferate in sediments with high levels of metal pollution. The effect of Zn on plant growth and tissue metal accumulation was assessed. The response of the plant to the inoculation with four different isolates of arbuscular mycorrhizal fungi (AMF) (Glomus sp. BEG140, Glomus claroideum, Glomus mosseae and Glomus intraradices) was studied. While the isolates of AMF ...

Liv.52 syrup, an Ayurvedic liver-tonic and extract of Solanum nigrum (one of the constituents of Liv.52) were orally administered (0.125 ml/kg b wt./day which is equal to human dose) to weaning rats for 11 weeks. Liv.52 treated rats exhibited better growth during 3rd to 8th week than those administered extract of S. nigrum or controls, after which period the body weight in all the groups gradua...

North East India is one of the mega biodiversity hot spot, also one of the richest reservoir of genetic variability and diversity of different crops. Here, natural distribution of non tuberous Solanum species is also found to be very rich. Despite the importance of Solanum species no information in the karyotype of the members of this taxa available in North East India is found. In the present ...

Aqueous (hydrophilic) and chloroform (Lipophilic) extracts of nine medicinal plants currently used in Egyptian traditional medicine to treat some gastrointestinal tract (GIT) disorders were tested for their gastro-protective effect against the incidence of peptic ulcer. Indomethacin-induced ulcer in a rat model was used for this testing. Mentha microphylla, Brassica oleracea Capitata (Cabbage),...

The 32-kDa photosystem II protein of the chloroplast is thought to be a target molecule for the herbicide atrazine. The psbA gene coding for this protein was cloned from Solanum nigrum atrazine-susceptible ('S') and atrazine-resistant ('R') biotypes. The 'S' and 'R' genes are identical in nucleotide sequence except for an A to G transition, predicting a Ser to Gly change at codon 264. The same ...

BACKGROUND All plants in nature harbor a diverse community of endophytic bacteria which can positively affect host plant growth. Changes in plant growth frequently reflect alterations in phytohormone homoeostasis by plant-growth-promoting (PGP) rhizobacteria which can decrease ethylene (ET) levels enzymatically by 1-aminocyclopropane-1-carboxylate (ACC) deaminase or produce indole acetic acid (...
