棉花不同基因型品种棉仁含油量及其与纤维品质性状的关系   总被引：1，自引：0，他引：1  

陈姣  陈金湘  江曲 《作物研究》2014,(1):27-30

对41个棉花品种的棉仁油分含量测定表明，不同品种间的棉仁含油量差异较大，平均含油量为31．19%，变幅为27．77%~40．36%，含油量最高的品种为‘中棉所16’，最低的品种为‘豫棉11号’。对41个品种的纤维品质分析结果表明，纤维品质最好的为‘海7124’，最差的为‘晋棉11号’。相关分析表明，棉仁含油量与纤维品质之间无统计学相关性，即可在不降低纤维品质的基础上，开展棉仁高含油量育种研究。  相似文献   

Water in oil based PGPR formulation of Pseudomonas fluorescens (FP7) showed enhanced resistance against Colletotrichum musae     

《Crop Protection》2014

Banana anthracnose incited by Colletotrichum musae is a serious disease in post harvest marketing stage. It occurs in almost all the banana growing countries. In the current study, 5 isolates of C. musae infecting banana cv nendran were collected from various district of Tamil Nadu. C5 isolate collected from Tiruchirappalli showed maximum virulent with (66.60%) PDI. In vitro efficacy of six Pseudomonas fluorescens superior strains were tested for their inhibition on mycelial growth of C. musae. P. fluorescens (FP7) showed significantly higher inhibition of 41.12 per cent over control and with a mean mycelial growth of 52.10 mm. Water in oil emulsion was used in the present research for formulation of P. fluorescens (FP7). The emulsion contained the following ingredients (w/w), sterile deionized water (45.25%), glycerine (4.00%), water-soluble wax ((0.75%), Tween 20 (2.50%), and a mixture of 19.00% soybean oil + 28.50% castor oil. The application of water in oil emulsion formulation significantly increased the yield (68.12 t/ha) compared to control (66.49 t/ha), and also increase in the activity of defense related enzymes viz., phenyl alanine ammonia lyase, peroxidase, polyphenol oxidase, catalase and β-1, 3 glucanase was observed which was followed by talc based formulation of Pf1 and FP7.  相似文献   

FT-Raman and FT-IR studies of the gluten structure as a result of model dough supplementation with chosen oil pomaces     

《Journal of Cereal Science》2020

The pomaces obtained after cold pressing oil production from oil seeds can be regarded as a source of many valuable nutrients such as unsaturated fatty acids, dietary fibre and antioxidants. The aim of the research was to determine the effect of five oil pomaces from black seed, hemp, pumpkin, milk thistle and primrose on the structure of gluten proteins. The model dough was supplemented with 3%, 6%, and 9% of the pomaces. Structural changes in gluten proteins were studied using Fourier transform Raman spectroscopy (FT-Raman) and Fourier transform infrared spectroscopy (FT-IR). Additionally, chemical composition of the pomaces was determined. Changes observed in the gluten structure resulting from the model dough supplementation with oil pomaces allow the pomace to be divided into two groups depending on the type and amount of fatty acids present in the pomaces. If the pomace contains a low number of fatty acids (black seed and pumpkin), pseudo-β-sheets are formed from β-turns and antiparallel-β-sheets in the gluten network. If the pomace contains a high number of fatty acids, non-aggregated β-structures are observed. Although the pomaces contain considerable amount of dietary fibre and polyphenols, comparison of the observed structural changes in gluten network with pomaces’ chemical composition indicates that the changes are connected with presence of fatty acids.  相似文献   

中俄东线天然气管道焊接消磁技术试验     

谭笑  刘少柱  吴晓光  柳尚  田磊 《油气储运》2020,(1):79-85

长输管道在建设、改线或维抢修作业时,常会遇到管道对口处有磁偏吹现象,使得在焊接施工时,电弧发生偏离,导致焊接缺陷甚至无法焊接施工,严重影响了工程进度及管道的本质安全。中俄东线天然气管道工程采用1422 mm口径、X80钢级管道,以往所采用的消磁方法和消磁设备已无法满足其大口径、高钢级管道的消磁作业。通过分析管道剩磁的产生机理和影响因素,得到不同消磁方法对中俄东线管道的适用性。通过现场试验验证直流消磁法,分析直流消磁和直流焊机消磁的优缺点及工作参数,提出可行性建议。  相似文献   

Breaching the black box: The role of ramps in Thai sustainable palm oil certification     

Elena Degli Innocenti  Peter Oosterveer  Arthur Mol 《Asia Pacific viewpoint》2020,61(1):85-101

Certification of sustainable palm oil as organised through the Round Table on Sustainable Palm Oil is based on a simplified understanding of the global palm oil value chain – according to which instructions about production practices can be directly translated from the palm oil mill to the primary producer. The reality of palm oil provision is much more complex than this as is shown in the case of Thailand. On the basis of qualitative field study in Southern Thailand this paper clarifies that intermediary stages, such as the collection of oil palm fruit bunches at the ramp, play a key role in the organisation of the chain. The fluidity and complexity of the palm oil flow at the local level complicates the promotion of sustainability through certification. Global and national stakeholders, such as processing and trading firms, non‐governmental organisations and national governments, should therefore open this black box of local dynamics to more effectively contribute to sustainability in palm oil supply.  相似文献

The economic value of a soybean [Glycine max (L.) Merr.] crop depends on yield and quality. The objectives of this study were to evaluate soybean lines for protein and oil content and to examine the break-even (BE) analysis of these traits combined with yield. Forty lines of maturity group (MG) IV or V were grown at four Arkansas locations for two years. Yield, protein, and oil content of each line were determined and compared to the check average for a BE comparison of the total economic value of the line. Results showed six profitable lines ($8.40 to $54.96 per metric ton based on yield) in 2008 and six profitable lines ($0.49 to $61.19 per metric ton based on yield) in 2009. Overall, in both MG, high-protein lines needed to yield more to be profitable, whereas high-oil lines had competitive yield, protein and oil content; R00-764 (MG IV), R05-71 (MG V), and R02-6185F (MG V) were competitive without added premiums.  相似文献
