Physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 MP) was studied on seed germination and plumule as well as radicule growth length in three species namely: Agropyron elongatum, Agropyron desertourm and Secale montanum. Polyethylene glycol (PEG) was used to provide appropriate water potentials. A total of 100 seeds in four replications (Petri dishes) were so...

Two experiments were carried out to determine the nutritive value and to evaluate the performance of growing rabbits fed on isoenergetic diets containing high moisture sorghum silage grain with low or high tannin levels. In the digestibility assay (experiment 1), the nutritive values of silages were determined with 30 New Zealand White rabbits, 15 males and 15 females, 55 days old, allotted in ...

Since twins weigh about 20% less than singletons at birth, maternal smoking may be a more severe risk for them than for singletons. Therefore, the effect of maternal smoking during pregnancy on birth weight was investigated in a group of 5376 twins. All necessary information was collected by a questionnaire filled out by the mother of the twins. Gestational age explains more than 75% of the var...
