in order to investigate the effect of different levels of biological fertilizers on potato performance (cv. marfona), an experiment was carried out as strip plot based on rcb design with 3 replications in 2011 at isfahan. treatments included nitrocara at 4 levels (0: control, 220, 330 and 440 ml.ha-1) as a first factor and nitroxin+ phosphate at 4 levels (0+0: control, 20+100, 30+150 and 50+200...

Effect of gallium nitrate on the pharmacokinetics and tissue accumulation of 67Ga was investigated in rats bearing turpentine oil-induced abscess. Gallium nitrate accelerated the blood disappearance of 67Ga, but this effect was less potent than that of ferric nitrate. The accumulation of 67Ga in liver was significantly lowered by gallium nitrate, but no significant decrease of 67Ga accumulation...

A study was done to relate the in vivo reduction of nitrate to nitrate uptake, nitrate accumulation, and induction of nitrate reductase activity in intact barley seedlings (Hordeum vulgare L. var. ;Numar'). The characteristics of nitrate uptake in response to both time and ambient concentration of nitrate regulated reduction and accumulation. Uptake, accumulation, and in vivo reduction achieved...

Present studies show that nitrate accumulation is the major factor influencing the water uptake by vegetables, but there is lack of knowledge on how the relationship between nitrate and water concentrations in different vegetable tissues. We determined nitrate accumulation and water content in vegetables of rape, Chinese cabbage, and spinach under different nitrogen levels (experiment I), 29 sp...

Two maize hybrids were grown under growth chamber conditions on solution or vermiculite medium that contained 2.5, 7.5, or 15 millimolar nitrate. The objectives were to determine: (a) the effect of nitrate supply on N metabolism and growth and (b) the interrelationship between nitrate uptake, flux, and reduction on the accumulation of reduced N and nitrate by the various plant parts and for the...

KAYMAK, H. C., 2013. Effect of nitrogen forms on growth, yield and nitrate accumulation of cultivated purslane (portulaca oleracea l.). Bulg. J. Agric. Sci., 19: 444-449 The present investigation was carried out to determine not only the most appropriate nitrogen form but also the effect of these forms on growth, yield, element content and nitrate accumulation of cultivated purslane (portulaca ...

As natural plant growth stimulators, amino acids are widely used to improve the yield and quality of crops. Change in enzymes activities of N assimilation (NR, NiR and GS), residual nitrate (NO3-), soluble protein content, and yield of spinach and lettuce plants were investigated under replacing 20% nitrate-N in the nutrient solution by L-glycine and blood meal amino acids. Seeds of the mention...
