In rat and some other species a diet with a high caloric per cent of rapeseed oil induces the rapid accumulation in their heart muscles of fat droplets, consisting mainly of triglycerides [ 1, 21. Macroscopically the hearts grow pale and the contractile force of the heart muscles decreases markedly after 2-3 days, The adverse effect of rapeseed oil is mainly caused by erucic acid (cis13-docosen...

Seed weight is a very important and complex trait in rapeseed (Brassica napus L.). The seed weight of rapeseed shows great variation in its natural germplasm resources; however, the morphological, cytological and genetic causes of this variation have remained unclear. In the present study, nine highly pure inbred rapeseed lines with large seed weight variation and different genetic backgrounds ...

A longitudinal cross-over feeding design was used to investigate the relationship of dietary lipid composition to the membrane lipid environment and activity of mitochondrial ATPase in vivo. Rats were fed a polyunsaturated fatty-acid-rich oil (soya-bean oil) for 12 days, crossed-over to a monounsaturated fatty-acid-rich oil (rapeseed oil) for the next 11 days, then returned to soya-bean oil for...

The effects of cover crops on the biology soybean cyst nematode (SCN; Heterodera glycines) are not well established. It is possible that may reduce SCN population densities by acting as trap crops. Cover with potential to serve stimulate hatching and/or attract hatched juveniles and also be penetrated large numbers nematodes cannot feed. Experiments were conducted determine whether root exudate...

in order to evaluate the effects of atmospheric co2 concentration increment on rapeseed salinity tolerance, four levels of salinity(0, 5, 10 and 15 ds.m-1) on  three cultivars of rapeseed (okapi, zarfam, and rgs) at three levels of atmospheric co2 concentration(350, 700 and 1050 ppm) were studied. the experiment was conducted at the greenhouse of tarbiat modares university at 2010 and 2011 crop...

The objective of this work is to study the effect of the rapeseed oil content on the physical properties of whey protein emulsion films. For this purpose, whey protein films with the addition of 0, 1, 2 and 3% of rapeseed oil, and glycerol as a plasticizer were obtained by the casting method. Film-forming emulsions were evaluated and compared using light scattering granulometry. The Sauter mean...

In this study, performed in the western part of the state of Paraná, Brazil, two self-fertile hybrid commercial rapeseed genotypes were evaluated for yield components and physiological quality using three pollination tests and spanning two sowing dates. The treatments consisted of combinations of two rapeseed genotypes (Hyola 61 and Hyola 433), three pollination tests (uncovered area, covered a...

Crop rotations that include tap-rooted species of cover crops may help alleviate the deleterious effects of soil compaction on plant growth by modifying soil physical properties. We studied the effects of compaction and cover crops on the least limiting water range (LLWR) and air permeability in the surface layers of a loamy (Exp. 1) and a sandy soil (Exp. 2). There were three compaction treatm...

To identify cultivars quickly and accurately, DNA fingerprinting of 10 broccoli varieties was performed by using simple sequence repeat (SSR) marker technology. Highly informative polymorphic SSR markers were screened rapeseed. Out the 93 pairs, 21 pairs selected found to have good polymorphism. Each pair generated 1 bands with an average 4.29. The polymorphism information content (PIC) 0.41 a ...

in order to evaluate the influence of different sowing dates on quantitative and qualitative yield in four winter rapeseed cultivars (brassica napus l.), two field experiments were carried out as split plot arrangement in complete block design with four replications. this research was performed in agricultural experimental station of agricultural and natural resources research center of markazi...
