Interactive effect of water deficiency, gibberellic acid and proline on maize

Research article of Journal of Plant and Environmental Research The interactive effect of the water deficiency, gibberellic acid and proline on the growth of maize MUSTAFA. R. AL-SHAHEEN1,2 Muaiad Hadi Ismael1 1Department of Field Crop, College of Agriculture, University of Anbar, Anbar, Iraq 2School of Bioprocess Engineering, University Malaysia Perlis, Perlis, Malaysia A field experiment was conducted in Padang Besar, Perlis, Malaysia from 15/2/2014 and 15/2/2015 two seasons. In each year, the experiments have been implemented in order to study the effect of three levels of irrigation water (25% (no stress), 50% (moderate deficit), 75% (water deficit) of field capacity), and five concentrations of GA3(0, 50, 100, 200, 300 ppm) and five concentrations of proline (0, 100, 200, 300, 400 ppm) on the yield and productivity of maize.The results showed a significant influence of sprayed GA3on the maize leaves, where excellence sprayed 300ppm GA3 with a high rate of all the study characteristics with sprayed 300ppm of gibberellic acid except cobs per plant. The results of the interaction between GA3and water deficit showed the clear influence of water deficit in reducing all characteristics of study where excelled the interactions (300ppm GA3 and 25% from field capacity) with a high rate of majority study characteristics, but these increases were not sufficient. Concluded from the results of the study great positive impact of sprayed proline on the all of the growth characteristics, it characterizes the concentration of 400ppm with the highest rate of majority study characteristics. The study results showed into increased the rate of protein, chlorophyll content, and oil, with sprayed 400ppm of proline.

Heavy metal levels in soils and three herbaceous species in phytoremediation

Research article of Journal of Plant and Environmental Research Assessment of Heavy Metal Levels in the Soils of Ohyia Kaolin Mining Site and Screening of Three Local Herbaceous Species for Use in Phytoremediation C.E.

Okafor4 1Lecturer, Environmental Management and Toxicology, Michael Okpara University of Agriculture, Umudike, 2Senior Lecturer, Environmental Management, Michael Okpara University of Agriculture, Umudike, 3PhD Student, Michael Okpara University of Agriculture, Umudike, 4Lecturer, Environmental Management and Toxicology, Michael Okpara University of Agriculture, Umudike The study assessed three local plant species Chromolaena odorata, Ipomoea involucrata and Mariscus alternifolius commonly found at abandoned kaolin mining site at Ohiya, Umuahia Abia state for their efficacy in phyto-remediation of heavy metals contaminated soil using a pot experiment. Soils from Ohiya kaolin mining site were used as medium for growing the species. Pre-experiment assessments of the concentrations of six heavy metals (Cr, Pb, Ni, Cd, Co and Se) were carried out in the soil and plant tissues to be used for the experiment. The experiment was laid out in a Randomized Complete Block Design (RCBD) with 6 replicate pots each. The physico-chemical properties of the experimental soil showed high content of lead (Pb) and cobalt (Co) contamination which were (2.40mg/kg) and (9.84mg/kg) respectively. Post-trial plant analysis revealed that the three plant species used for the study accumulated appreciable quantities of the heavy metals. The ranges of Pb in the species were as follows C. odorata (0.80-1.00mg/kg), I. involucrata (1.00-2.00mg/kg), M. alternifolius (0.40-0.70mg/kg). The ranges of Cr were: C. odorata from (0.00-0.07mg/kg), I. involucrata (0.30-0.42mg/kg), M. alternifolius (0.01-0.10mg/kg). The ranges of Cd in the species were: C. odorata (0.02-0.30mg/kg), I. involucrata (0.10-0.70mg/kg), M. alternifolius (0.10-0.60mg/kg) and Co concentrations were: C. odorata (2.00-3.07mg/kg), I. involucrata (2.01-4.01mg/kg), M. alternifolius (2.01-2.10mg/k). Ipomoea involucrata had significantly higher accumulation of Pb and Co ...

Toxicological effects of Ambrosia maritima in Nubian goats

Research article of Journal of Plant and Environmental Research Toxicological effects of Ambrosia maritima in Nubian goats Ilham, M.O. Ahmed1, Mohammed, A.S.1, Halima, M. O.1 and Ibtehal, M.A. Ahmed2 1 Veterinary Research Institute, P.O. Box: 8067 (Al Amarat), Khartoum/Sudan 2 Faculty of Medicine University of Khartoum/ Sudan Toxicity of Indigenous plant Ambrosia maritima was investigated. Twenty fore, 6-8 month old, 12 female and 12 male of Sudanese Nubian goats were used. Dried Leaves powder of Ambrosia maritima was mixed with water and given orally by drench to the animals at a dose of 1000 or 2000mg/kg/day for 126 days. Two females drenched the plant at a dose of 1000mg/kg/day, were died at day 8 and 9 post treatment and one female drenched the plant at a dose of 2000/kg/day died at day 13. The results revealed that goats drenched the plant for 126 days, showed chronic toxicity evident by clinical symptoms, pathological and biochemical changes. The main symptoms were watery diarrhea, inappetance, respiratory distress and depression. Later these symptoms disappeared and the animals appeared healthy. The most evident pathological features were hydrothorax, hydropretonium, hydropericardium, and enlargement of the liver. Histopathological changes were exemplified by degeneration and necrosis of the hepatic cells. Focal necrosis, congestion and haemorrhag of proximal convoluted tubules. Necrosis of intestinal vili with severe infelteration of inflammatory cells. Congestion of alveolar capillaries and pancreatic hyperplasia. These changes were correlated to the activity of Asparate Aminotransferase (AST), Alkaline phosphate (ALP), the concentration of cholesterol, sodium and potassium in the serum, and with the hematological values. The effect of the plant on males was less marked compared to that on female goats. There was gradual increase in mean body-weight of both sexes.
