abstract the aim of the present research was to isolate plant growth promoting rhizobacteria producing acc deaminase which was able to alleviate negative effects of salinity on plant growth. 21 composite soil samples and canola roots were collected from the saline and relatively saline soils of qom and qazvin provinces. 105 strains were selected from the soil rhizosphere of canola. according to...

Ethanol and biodiesel production have become important industries worldwide. For example, ethanol production in the United States has increased exponentially from 6.0 billion liters in 2000 to 49 billion liters in 2010, an increase of 800% (RFA, 2011). Similarly, biodiesel production increased in the U.S. from 424 million liters in 2005 to 1,191 million liters in 2010 (NBB, 2011). These booming...

The objective of this study was to evaluate the effect aluminum and mitigating potential H2O2 on stress antioxidant responses in canola (Brassica napus var. oleifera (Moench) Delile) affecting emergence initial growth plants. Canola seeds, cultivar Hyola 61, were treated with different concentrations solution (0.0, 0.075, 0.15 M), later sown under 10, 20, 30 mmolc dm-3). After 20 days plant eme...

Present study investigated the effects of dietary increasing levels of solventextracted canola meal (CM) as a substitute for soybean meal as an energy and amino acid source in finishing pigs. A total of 192 finishing pigs (Landrace × Yorkshire × Duroc; initial body weight of 48.62 ± 3 kg) were randomly allotted to 4 treatments on the basis of BW. There were 4 replicate pens in each treatment wi...

Allelopathy is one crop attribute that could be incorporated in an integrated weed management system as a supplement to synthetic herbicides. However, the underlying principles of crop allelopathy and secondary metabolite production are still poorly understood including in canola. In this study, an allelopathic bioassay and a metabolomic analysis were conducted to compare three non-allelopathic...

cold stress is considered as a restricting factor in plant production. recently, many different compounds were applied to minimize the harmful effects of stress. in this study, the effects of foliar application of salicylic acid was studied on some biochemical properties of two different cold resistant canola cultivars. salicylic acid was sprayed at four concentrations (0, 100, 200 and 400 µm) ...

in order to determine the critical period of weed control and investigation the effect of periodical control and interference of weeds natural population on yield and yield components of winter canola (brassica napus l. cv. okapi) in west region of tehran an experiment was carried out at research field of tarbiat modarres university, tehran, iran on 2004-5 growing season. fourteen experimental ...

The apparent digestibility coefficients (ADC) of unprocessed and processed pea, canola and flax products were determined on diets, in which 30% of a reference diet was replaced by each test ingredient. Celite was used as an indigestible marker for measuring apparent digestibility coefficients indirectly. The trial was conducted in a semi-closed recirculating system using 5 tanks per diet with 4...

The objective of this study was to examine the effects of dietary forage level and fat supplementation on the chemical composition of mixed ruminal bacteria (MRB). Six ruminally cannulated beef steers (354 kg +/- 18) were given ad libitum access to six diets (13.2% CP; DM basis) that were offered twice daily in a 6 x 6 Latin square design. Treatments were arranged as a 2 x 3 factorial with two ...
