seed reserves are controlled by genetic and environmental condition such as nutrition, temperature, drought stress and light intensity. strong seedling will produce from seeds with high reserves. therefore, in this work that conducted in pot, field(in tabriz university) and lab(in shahrood university of technology) experiments, effect of pre-anthesis nitrogen application and a drought stress du...

There are obvious analogies between disorders of intestinal amino-acid absorption and the more familiar anomalies of carbohydrate absorption. Both monosaccharides and free amino acids are important water-soluble nutrients which must be transported across the lipid-containing intestinal cell membrane by specific active transport processes involving concentration of the compounds within the cell ...

1. Gel filtration of the water-soluble radioactive mucus produced three radioactive fractions, fraction A excluded on Sepharose 4B, fraction B included on Sepharose 4B but excluded on Sephadex G-200, and fraction C included on Sephadex G-200. 2. The specific radioactivities of fractions A and B were the same, with fraction C a little lower, whether the material was labelled with (14)C-labelled ...
