To reveal the physiological and biochemical mechanism underlying graft union formation in pecan (Carya illinoinensis), dynamic changes content of nutrients, tannin, phytohormones together with key enzyme activities were investigated 0, 3, 5, 7, 10, 14, 18, 22, 31, 40 d after grafting (DAG), homograft unions. During formation, peroxidase (POD) activity increased at 7 - 10 DAG compared that 0 DAG...

Pure oxygen at 1 atm exerts two opposite effects on Pseudomonas saccharophila: it inhibits sucrose uptake and lipid synthesis, but it enhances the formation of polysaccharides.

Landscape groundcover plants are a diverse group of trailing or spreading species that naturally form continuous soil coverage.Ground cover plants that were used in this study consisted of vegetative propagules of: Vinca minor L. ٬Variegatum’, Vinca minor L. ٬Green’, Oxalis brasiliensis G. Lodd, Trifolium repens L., Phyla nodiflora L. and Frankenia thymifolia Desf. The aim of this study was to ...

chlorpyrifos, an organophosphate pesticide, is widely used to control pests in agriculture farms and orchards of fruit trees. in this study, the fish were exposed to sub-lethal concentrations of chlorpyrifos which were determined based on numerical value of 96 h lc 50 . blood was sampled after 10, 20 and 30 days and biochemical parameters including glucose, total protein, albumin, globulin, tri...

background: milk fever in cattle, sheep and goats occurs  around the time of parturition and is caused by hypocalcemia. objectives: the aim of this study was to investigate the physiological effects of experimental hypocalcemia on electrocardiography, hematology and serum biochemical changes in markhoz goat breed. methods: ethylene diamine tetra- acetate solution 4.6% was intravenously infused ...
