in order to study the role of photosynthetic tissues on grain filling and remobilization of stem reserves under terminal drought, a pot experiment as semi-field was conducted as two-factor factorial in complete randomized design with three replicates at research farm of agriculture college of vali – e – asr university of rafsanjan during january to june 2012 . first factor was source strength r...

Until recently methods of amino-acid analysis had been applicable only to purified proteins. In a few instances the effects of impurities have been partly ascertained, noteworthy being the work of Chibnall and his colleagues (Chibnall, 1939) and of Lugg (1938a) on the crude proteins of grasses. The development of the microbiological method in recent years has led to an extension of analysis to ...

The water-soluble fractions of three crude and two refined oils reduced the growth rate and maximum cell density of the marine bacterium Serratia marinorubra grown in batch culture. The weathering of a crude and a refined oil was simulated in the laboratory. The water-soluble fractions remaining from this process were more toxic to S. marinorubra than were the parent unweathered oils. Increases...

Modern feed additives based on natural plant components are increasingly used as an alternative to synthetic antibiotics in animal nutrition. Phytobiotics that gaining demand for use ready-to-eat and provide proper health microflora of the body. A scientific economic experiment was conducted order determine their effect productivity young pigs. We composed three groups analogues each comprising...

Fructans, storage carbohydrates with beta-fructofuranosyl linkages, are found in approximately 15% of higher plants. The metabolic flexibility of those molecules allows them easily to polymerize and depolymerize to soluble carbohydrates according to plant development stage and environmental conditions. In this work, water-soluble carbohydrates, including fructan structure patterns, were compare...

to evaluate the quantitative and qualitative of forage in intercropping of sorghum and chickling pea under limited irrigation systems, an experiment was conducted in research farm, college of agriculture, university of tehran, during 2009 and 2010. the treatments were arranged as split plots consisted of three levels of irrigation regimes including control (irrigation after 70mm evaporation fro...
