‘Ogi’ was produced from yellow variety of maize to obtain a fermented gruel from ogi and the effect of moringa leaves fortification on the nutritional value and the sensory properties of yellow maize-ogi was investigated. The moringa leaf powder was substituted into yellow maize-ogi in these formulations; 100:0, 90:10 and 85:15. The effects of the moringa leaves powder substitution on the proxi...

A randomized complete block (RCBD) study was designed to investigate the effects of cadmium (Cd) and copper (Cu) on the growth, bioaccumulation of the two heavy metals, metabolite content and antibacterial activities in Gyanura procumbens (Lour.) Merr. Nine treatments including (1) control (no Cd and Cu); (2) Cd 2 = cadmium 2 mg/L; (3) Cd 4 = cadmium 4 mg/L; (4) Cu 70 = copper 70 mg/L; (5) Cu 1...

AIM This study was designed to determine the proximate composition and mineral content of Costus afer leaf and stem, as well as to identify the most active antioxidant fraction. MATERIALS AND METHODS The proximate composition and mineral analysis of C. afer leaf and stem were performed using the standard methods described by Pearson and Association of Official Analytical Chemist while the 1,1...

Wounding of tomato (Lycopersicon esculentum L.) leaves causes systemic induction of a serine-type carboxypeptidase activity. We find this activity to be present in several isoforms. Antibodies raised against the leaf carboxypeptidase inhibited the enzyme activity and the immunoprecipitates were resolved into a 69-kDa polypeptide and a doublet of 35/37-kDa proteins on SDS-PAGE. Immunoblot analys...

The absorption of Cu(2+), Zn(2+), and Mn(2+) by leaf tissue of 4-month old sugarcane plants (Saccharum officinarum L., var. H53-263) has been investigated. After the "apparent free space" fraction was desorbed, the absorption of Cu(2+), Mn(2+), and Zn(2+) yielded a curve typical of many ion uptake processes when measured as a function of the external concentration. However, only 1 absorption me...

heavy metals found in urban air with its toxic effects have a direct impact on human health. selection of appropriate tree species and shrub refining capacity of heavy metals in urban areas can greatly reduce the toxic effects of these materials. this study aimed to identify the most suitable tree and shrub species of broadleaf evergreen, deciduous and coniferous refinement of heavy metals lead...

The bacterial spot of tomato, caused by Xanthomonas spp., is a very important disease, especially in the hot and humid periods of the year. The chemical control of the disease has not been very effective for a number of reasons. This study aimed to evaluate, under greenhouse conditions, the efficacy of leaf-spraying chemicals (acibenzolar-S-methyl (ASM) (0.025 g.L(-1)), fluazinam (0.25 g.L(-1))...

Private vegetable gardens are often contaminated with elevated levels of heavy metals (HM). Bioindication, using the visible symptoms developing in leaves, can provide simple, cost-effective and reliable detection of soil pollution. In this experiment five species of vegetables from different families were exposed to soil contaminated with HM dust given as copper / zinc / cadmium/ lead = 640 /3...

Arbuscular mycorrhizal (AM) fungi establish a mutualistic symbiosis with the roots of most plant species. While receiving photosynthates, they improve the mineral nutrition of the plant and can also increase its tolerance towards some pollutants, like heavy metals. Although the fungal symbionts exclusively colonize the plant roots, some plant responses can be systemic. Therefore, in this work a...
