this study was carried out on olive trees cv. amygdalifolia, to investigate the effect of spraying potassium nitrate, kno3, and zinc sulfate, znso4, on the fruit weight, dimension and volume. the plants were sprayed with 0, 0.5, 1.0 and 1.5% kno3 and 0, 0.25, 0.50 and 0.75% znso4 and their combinations in august about halfway through the fruit growth period. the highest fruit weight was observe...

Depriving homing pigeons of olfactory information by spraying an 18% zinc sulphate solution onto their olfactory ephithelium results in anosmia that persists for at least 5 days (tested using the ‘orienting response’). To study whether anosmic zinc-sulphate-treated pigeons (ZnSO4-pigeons) were able to compensate for their loss of olfactory information by using familiar landmarks, we made releas...

excessive vegetative growth may bring about improper pollination and consequently lead to reduced fruit set and misshapen fruits. paclobutrazol (pp333) reduces vegetative growth. on the other hand, balanced nutrient uptake at all developmental stages increases fruit quality and yield. an experiment was conducted with the aim of reducing vegetative growth and improving yield of strawberry, selva...

Escherichia coli strains from sewage sample were screened for the presence and expression of heavy metal-translocating zntA gene by PCR and RT-PCR analysis with type culture of K-12 as standard strain. The strain which showed high level of gene expression (SBVP1) was chosen to further study the growth and heavy metal translocation. This superior strain was grown in the presence of ZnSO4, Pb (CH...

We have previously observed that UCB binds to ZnSO4 in vitro, and suppressed the biliary bilirubin secretion in the hamster. The aim of this study was designed to investigate whether Zn salts might inhibit the enterohepatic cycling of UCB in subjects with Gilbert s syndrome. Fifteen patients with Gilbert s syndrome and 5 normal healthy volunteers were included in this study according to the fol...

Background: Several treatment modalities have been used for cutaneous leishmaniasis (CL) with various results. In vitro and in vivo studies have shown inhibitory effects of zinc sulfate (ZnSO4) on Leishmania parasites. Objective: To compare the efficacy of intralesional injections of 2% ZnSO4 solution with meglumine antimonate (Glucantime) in the treatment of acute Old World CL. Patients ...

The toxic implications of fresh water contamination with zinc in the catfish, Clarias albopunctatus (Lamonte and Nicole, 1927), and the effect of a co-contamination with a sub-lethal dose of glyphosate (Roundup) was studied using the static bioassay model. Thirty six fish were divided into 3 equal groups. Fish in Group 1 were placed in normal tap water, and served as the control group, while fi...
