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 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...

The purpose of the research is increasing yield spring rape in Tatarstan pre-Kama zone. Soil pollution affects food safety both by reducing plant performance and class. Oil petrochemicals are common con-tamination sources environment. work devoted to assessment impact oil soil on rapeseed. study was conducted experimental field Department «Agro-chemistry Science» Kazan State Agrarian University...

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...

yield, harvest index and morphological characters of 13 spring cultivars of rapeseed were evaluated in 2007 growing season at agriculture and natural resources research station of torogh, mashhad. these cultivars were from three rapeseed species belonged to brassica napus, brassica rapa and brassica juncea. experimental design was randomized compelet block with four replication. result showed t...

in order to study of yield, yield component, plant height, total dry matter and radiation use efficiency with 13 spring varieties of rapeseed ,an experiment was carried out in 2007 growing season at agriculture and natural resources research station of torogh,mashhad. these cultivars were from three rapeseed species belonged to brassica napus, brassica rapa and brassica juncea. experimental des...

The present study was conducted to measure the flow of microbial and nonmicrobial N fractions entering the omasal canal of lactating dairy cows fed grass-red clover silage supplemented with barley and rapeseed meal. Four ruminally cannulated Finnish Ayrshire dairy cows were fed, in a 4 x 4 Latin square design, grass-red clover silage alone or supplemented with (on DM basis) 5.1 kg/d of barley, ...
