Five hundred and ninety two Siberian sturgeon fingerlings (average weight, 11.1±0.9 g) were randomly distributed in 16 tanks (150 L) at a density of 35 fish per tank and fed different treatments (Control, degrading bacteria, 2% PHB, degrading bacteria + 2%PHB) for 60 days. At the end of the experiment, no significant difference was observed in case of final weight in fingerlings but fish fed PH...

Drought is one of the major factors limiting crop production in Iran. Twenty Iranian wheat cultivars with wide range of sensitivity to drought, including 18 varieties of bread wheat and two varieties of durum wheat were used in two separate field experiments in 2009-2010 at the Experimental Station of College of Agricultural in Shiraz University. Each experiment was conducted as a randomized co...

This research was conducted to investigate the changes of GA3-like substances in the stratified (0, 10, 20, 30 days at 10oC) and non-stratified seeds of two olive cultivars, namely ‘Arbequina’ and ‘Zard’. In the first experiment stratified seeds of these cultivars (10 g) were extracted with ethanol (80%), purified by ethyl acetate, and then separated by thin layer chromatography (TLC). To compa...

Considering low vigor of Stevia (Stevia rebaudiana Bertoni) seeds and difficulty of its germination, the purpose of this experiment was to evaluating the effect of different priming types on germination and seedling growth of Stevia in the presence of gibberellic acid. A factorial experiment was carried out based on a completely randomized design with three replications. Treatments consisted of...
