n order to investigate the effect of nitrogen fertilizer rates and top dressed on nitrogen remobilization in different rice cultivars, a field experiment was conducted in the rice research institute of iran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 factors were used in which fertilizer rates in 3 levels (including 46,...

A device has been developed for the direct in situ measurement of metal remobilization into solution from settling particles in water columns, based on the technique of diffusion gradients in thin films (DGT). The device comprises a hollow cylinder with a DGT assembly at its base and acts as a traditional sediment trap, except that any remobilization from settling particles is reflected in the ...

to investigate the effect of nitrogen rate and split form of application on dry matter remobilization among different rice cultivars, a field experiment was carried out in the rice research institute of iran (amol) – during 2005. a split–split experiment on the basis of a randomized complete block design with 3 replications involving 3 factors was employed in which fertilizer rates (100, 150 an...

Higher plants have to cope with fluctuating mineral resource availability. However, strategies such as stimulation of root growth, increased transporter activities, and nutrient storage and remobilization have been mostly studied for only a few macronutrients. Leaves of cultivated crops (Zea mays, Brassica napus, Pisum sativum, Triticum aestivum, Hordeum vulgare) and tree species (Quercus robur...

Studies of small trees growing in pots have established that individual amino acids or amides are translocated in the xylem sap of a range of tree species following bud burst, as a consequence of nitrogen (N) remobilization from storage. This paper reports the first study of N translocation in the xylem of large, deciduous, field-grown trees during N remobilization in the spring. We applied 15N...

BACKGROUND Muscle mass and function are perturbed by immobilization and remobilization. When muscle mass changes, the quality and quantity of the extracellular matrix protein, particularly the collagens, change with it. In this study, we investigated the temporal profile of three peptide biomarkers derived from turnover of collagen type III and type VI in a long-term immobilization and remobili...

dry matter remobilization, grain filling rate and duration has principle role on rice grain yield, and environment condition directly affect on them. for study the influence of climate factors a factorial field experiment in randomized complete blocks design with three replications conducted at haraz extention and technology development centre in spring 2013. treatments included rice cultivars ...

Bioturbation/bioirrigation can affect the remobilization of metals from sediments. In this study, experiments were performed to examine the effect of bioturbation/bioirrigation by different organisms on cadmium (Cd), copper (Cu), zinc (Zn) and lead (Pb) releasing from the spiked sediment. The diffusive gradient in thin films technique (DGT) revealed that at the end of exposure time, the labile ...
