TL;DR: Zhang et al. as discussed by the authors used a novel method to detect the survival rate of rape seedlings at multiple growth stages in the plant factory, which can not only improve the space utilization of plant factories, but also help increase crop yields.

TL;DR: Turkey poult starting rations stimulated weight gain from 1 day to 6 weeks of age and improved efficiency of feed utilization, but the addition of rapeseed oil to the ration depressed weight gain as compared to the basal (low-fat) ration.
Abstract: The effects of including soybean oil, sunflower oil, rapeseed oil, or animal tallow in turkey poult starting rations were studied. Male, broad-breasted Bronze poults were used and the fat sources were tested at 5% and 10% of the ration.The inclusion of soybean oil, sunflower oil, or animal tallow in the starting rations stimulated weight gain from 1 day to 6 weeks of age and improved efficiency of feed utilization. However, the addition of rapeseed oil to the ration depressed weight gain as compared to the basal (low-fat) ration. The magnitude of growth depression was directly related to the rapeseed oil content of the ration. The comparative ration metabolizable energy data indicate that dietary energy supplied by rapeseed oil was as available to poults as energy supplied by other fat sources. Poults consuming rations containing 5% or 10% rapeseed oil consumed less feed than did poults consuming all other rations. Decreased feed consumption was apparently responsible for the depressed weight gains of the...

TL;DR: The genotype Siren is recommended for general cultivation in the area and further use in breeding programmes for Brassica napus because of its high yield and oil quality.
Abstract: Five rapeseed genotypes were evaluated for agronomic parameters, yield, oil quantity and quality. Significant differences were observed for all the parameters except oil and protein percentage. The genotype Siren outperformed the rest of genotypes in yield potential (1104 kg/ha), followed by MRS-1 (866.67 kg/ha). For yield contributing characters like length of inflorescence and pods per plant, genotype Siren again showed good results that are, 51.3 cm and 136.5 pods/plant, respectively. The genotype Siren also showed low glucosinolate (44.82 imol/g), erucic acid (23.67 imol/g) and higher amounts of oleic acid (59.01%). Due to its high yield and oil quality, the genotype Siren is recommended for general cultivation in the area and further use in breeding programmes for Brassica napus.

TL;DR: In this paper , three kinds of natural oil bodies (OBs) with different components and surface membrane structure were extracted from rapeseed, camellia and flaxseed, respectively, and their compositions and structural characteristics had been fully characterized by SDS-PAGE, low field nuclear magnetic resonance (NMR), the cryo-Scanning Electron Microscope etc.

TL;DR: The introduction of the hrf2 gene into rapeseed can be an effective strategy for enhancing resistance to S. sclerotiorum, according to a comparison between agronomic characters of transgenic and control lines.
Abstract: hrf2 gene is a member of the harpin-encoding gene family of rice-pathogenic bacterium Xanthomonas oryzae pv. oryzicola. In our previous studies, we observed that harpinXooc could elicit hypersensitive cell death in non-host plants, induce disease and insect resistance in plants, and enhance plant growth. In this study, the rapeseed cultivar, Yangyou 4, was genetically engineered via Agrobacterium-mediated transformation to express the hrf2 gene. Polymerase chain reaction (PCR) and southern blot analyses of T1 generation of transgenic rapeseed revealed stable integration and expression of the inserted gene hrf2. In addition, the resistance to Sclerotinia sclerotiorum was greatly enhanced. A comparison between agronomic characters of transgenic and control lines displayed significant differences in terms of plant height, stem width, number of pods per plant, number of seeds per pod, 1,000-seed weight, and seed yield per plant. Among lines with resistance to S. sclerotiorum, T11 had improved agronomic traits compared with controls with a 22.7% seed yield increase. These results suggest that the introduction of the hrf2 gene into rapeseed can be an effective strategy for enhancing resistance to S. sclerotiorum.
