Role of arbuscular mycorrhizae in development of salt-tolerance of Trifolium alexandrinum plants under salinity stress.

Abstract

Experiments were conducted to evaluate the effect of egg weight on egg quality traits. One hundred and fifty eggs of three grade sizes (small 48.937 g, medium 54.885 g and large 60.385 g) with 50 eggs for each size group were collected from the brown-egg layer strain of Nike and used to determine the egg quality traits. Egg weight (EW) significantly affected the shape index, shell thickness, yolk weight percentage, albumen weight percentage, albumen height and Haugh unit (P 0.05). In overall, although there were significant positive correlations between EW and shape index, EW and shell thickness and EW and albumen weight percentage, there were significant negative correlations between EW and shell weight percentage and EW and yolk weight percentage. It was concluded that it was feasible to assess some egg quality traits through the egg weight.
