Effects of doses of gibberellic acid (GA3) were studied on the growth and performance of strawberry cultivar ‘Chandler’. GA3 was applied as foliar spray at three leaf stages @ 50, 75, 100 and 150 ppm. The applied GA3 @ 150 ppm significantly increased the plant height, leaf area index (LAI), crown size and fruit yield. However, this dose of GA3 (150 ppm) significantly decreased the shelf life an...

formalin is a common disinfectant and therapeutic agent in fisheries-related activities. considering large variation in susceptibility of different species to formalin toxicity, it is necessary to determine its toxicity and safety margins in different species, separately. therefore, to investigate formalin acute toxicity and safety margins on caspian roach, an experiment was conducted in 1g cas...

Two experiments were conducted to evaluate the responses to carbadox and Cu additions in the postweaning diet of swine. The first trial contained 470 pigs in five replicates in a 2 x 5 factorial arrangement in a randomized complete block design. Weanling pigs 4-wk of age were fed diets containing 0 or 55 ppm carbadox and 0, 125, 250, 375 or 500 ppm Cu for a 5-wk period. Copper levels of 125 and...

The present study was carried out to show the negative impact of different concentrations sodium chloride (100, 150, 200, 250 and 300 mM) on germination rate 7-day old maize seeds, according results by measuring growth criteria germinated seeds both mM Nacl these concs nearly lethal seed so, ignored in next experiments complete step with three only 150 200 Nacl.

The aim of the study was to evaluate the relevance of cations in different fluoride compounds for their effectiveness as anti-erosive agents. Human enamel samples underwent a de- and re-mineralisation procedure for 10 days. Erosive demineralisation was performed with 0.05 M citric acid (pH 2.3) 6 x 2 min daily followed by immersion in the test solution 6 x 2 min each. Test solutions were: SnCl2...

Two 28-d experiments were conducted to evaluate the efficacy of low dietary concentrations of Cu as Cu-proteinate compared with 250 ppm Cu as CuSO4 with growth performance, plasma Cu concentrations, and Cu balance of weanling swine as the criteria. In the production study (Exp. 1), 240 crossbred pigs that averaged 19.8 d of age and 6.31 kg BW initially were group-fed (two or three pigs per pen)...

Five bacterial strains for biodegradation study were initially isolated from quinalphos exposed soil cotton field of Indian Agricultural Research Institute, India by Serial dilution and enrichment technique. Amongst them, two Pantoea agglomerans Acinetobacter sp. dcm5A to different concentrations (50-250 ppm, parts per million) evaluate their tolerance the optimum concentration supported growth...
