to evaluate general and specific combining ability for resistance to bolting and cercospora leaf spot, 36 hybrids derived from crosses between 9 sugar beet lines along with four checks were planted in safiabad agricultural research center (dezful) in 2008-2009. the experimental design was a triple lattice design with three replications. analysis of variance showed significant differences among ...

The effects of potassium fertilizer (K2SO4) levels K0, (0), K1,(150) and K2,(250 kg/ha) in two species of Brassica napus (Hyola 401 Hybrid) and Brassica juncea (landrace cultivar), under three irrigation regimes, control (irrigation after 50%,), moderate stress, (irrigation after 70%), and severe stress (irrigation after 90% soil water depletion) were studied in a factorial experiment laid out ...

A certain proportion of laboratory rats of various strains show spontaneous nonconvulsive ECoG seizures in the form of bursts of spike-and-wave discharges (SWD). Since in the majority of behavioural experiments the EEG is not controlled, the experimenter is usually unaware of this fact. The purpose of the present work was to find out whether the SWD trait is related to the rats behavioural perf...

OBJECTIVES To determine whether carbamazepine (CBZ) aggravates absence seizures in the low-dose pentylenetetrazol (PTZ) rat model in both male and female animals, and investigate for gender differences. METHODS Inbred Sprague-Dawley rats were implanted with EEG electrodes. Seven days later PTZ (20 mg/kg, i.p.) was administered following pre-treatment with vehicle or CBZ (20 mg/kg, i.p.) and t...

abstract in order to study the effects of irrigation regimes and plant spacing on bulb yield of two onion (allium cepa l.) genotypes, an experiment was conducted at kabootar abad research station of isfahan during two growing seasons (2005 and 2006). the experiment design was split-factorial with a randomized complete block arrangement with four replications. main plots included three irrigatio...
