纤维亚麻秋播优化高产栽培技术

亚麻属于亚麻科、亚麻属、栽培亚麻种,是亚温带喜冷凉长日照、直根系作物.按其经济特征,可把有栽培价值的亚麻划分为纤用亚麻、油用亚麻和油纤兼用亚麻三大类型.纤用亚麻从原茎到种子都可以加工利用,具有较高的经济价值.实施冬季农业开发,发展秋播亚麻产业,是优化农业产业结构和促进农村经济发展,增加农民收入的有效途径.秋播亚麻产业已在大理州形成强劲的发展势头,由于在不同栽培条件下种植亚麻的产量和经济效益差异较大,要提高亚麻原茎产量和工艺质量的整体水平,促进增产、增收、增效,就必须坚持因地制宜、适时播种、合理密植、加强管理、适时收获,做到种好、管好、收好.

世界麻类原料生产与贸易概况(Ⅱ)

第二篇亚麻栽培亚麻(Linum usitatissim um L.)属亚麻科(Linaceac)亚麻属(Linum),简称亚麻。亚麻分纤用、油用和油纤兼用型三类。亚麻是最古老的栽培作物之一,亚麻纤维是人类最早开发利用的天然纤维。早在公元前4000-5000年,埃及人就开始种植亚麻,并以亚麻织物品质优良而驰名于世。早在新石器时期,亚麻就经埃及传入地中海沿岸地区,中世纪以后又传到法国、英国、比利时、荷兰、俄罗斯和罗马尼亚等国。我国河北、云南、黑龙江、西藏等省(自治区)虽有多年生野生亚麻的分布,但亚麻在我国古代一般作药用和油用,纤用亚麻种植和利用很晚,1906年才…

黑龙江省油用亚麻栽培技术

黑龙江省一直以栽培纤维型亚麻为主，进入21世纪后，国内外亚麻纤维市场需求发生较大变化，致使我省纤维亚麻种植面积逐步减少。为发挥我省亚麻产业资源优势，我省亚麻主产区用油用亚麻替代部分纤维亚麻种植，相继建设以亚麻籽为原料的加工企业，开发出亚麻油、阿尔法亚麻酸、亚麻胶、亚麻冲剂等多个新产品，销往日本、韩国等东南亚国家。本文主要阐述黑龙江省油用亚麻栽培需要的生态环境，土壤、品种、施肥、病虫害防治等技术要点。同时提出油用亚麻和纤维型亚麻不同的技术要求及对策。

栽培亚麻的遗传多样性研究

基于110份来源于世界各地的亚麻(Linum usitatissimum)资源(栽培品种和育种材料)和1个野生近缘种L.bienne,利用AFLP技术研究形态学上不同的亚麻,即纤维亚麻和油用亚麻的遗传多样性.聚类分析结果表明,L.bienne明显区别于其他样品,自展值高;纤维亚麻与油用亚麻和不明用途亚麻也能区别开来,但自展值偏低.主成份分析显示,纤维亚麻与油用亚麻区别明显,但L.bienne与油用亚麻之间难以区别,荷兰、法国的纤维亚麻与其他国家的纤维亚麻亦可明显区别,这说明亚麻基因库出现了类群结构.分子方差分析显示,纤维亚麻的变异度低于油用亚麻及不明用途亚麻,因此,油用亚麻和野生亚麻L.bienne是丰富纤维亚麻基因库的潜在种质资源.

Respiratory bacterial flora from healthy as well as respiratory symptoms' subjects

Respiratory system is the primary settlement place of opportunistic organisms and considered as chief carrier of common respiratory pathogens. The aim of the study was to know the opportunistic organisms present in the healthy subjects as well as subjects that were suffering from respiratory symptoms. The organisms were identified as per standard bacteriological protocol and pathogenicity tests of the identified organisms were performed in mouse model. Antibiotic sensitivity of the identified organisms was performed. The bacterial flora present in the throat swab of apparently healthy as well as subjects suffering from respiratory symptoms were: Staphylococcus spp. (39.44%) of which Coagulase positive Staphylococcus (21.13%) and Coagulase negative Staphylococcus (18.31%), Klebsiella spp. (19.72%), Pseudomonas spp. (15.49%), Proteus spp. (4.23%), E. coli (9.86%) and Bacillus spp. (11.27%). Among the isolates Staphylococcus, Klebsiella and Pseudomonas were the predominant species. Percentages of identified bacteria were higher in respiratory symptoms exhibiting individuals (53.52%) than apparently healthy individuals (46.48%). All coagulase positive Staphylococcus, Klebsiella spp. and Pseudomonas spp. isolated from respiratory symptoms' subjects were found to be pathogenic. The isolated bacteria were resistant to amoxicillin and ampicillin but sensitive to ciprofloxacin and norfloxacin. Isolated Pseudomonas spp. showed multidrugs resistant properties. The study provided information about the pathogenic organisms' present respiratory systems of apparently healthy as well as subjects suffering from respiratory symptoms. The pathogenic natures of the isolated organisms were determined to make aware of scientists as well as clinicians. Antibiotics sensitivity assays would provide information to the clinicians for the selection of appropriate antibiotics to treat their patients.     

小麦籽粒品质与基因型及环境条件的关系

小麦籽粒品质性状与加工特性具有密切的关系,是小麦品种的主要经济性状,也是国际贸易中评价小麦品质和制定价格的依据。本文综述了小麦籽粒品质与基因型以及温度、光照、降水、土壤类型、病虫害、播期、施肥等生态环境和栽培条件之间的关系。小麦籽粒品质主要受基因型控制,也受气候和土壤等环境条件的影响。在环境因素中,气温和降水量的变化对小麦籽粒品质影响尤为明显。在生产实践中,针对影响小麦籽粒品质变异的关键因素,在不同环境条件下,选育和种植适宜的品种,采取合理的施肥和灌溉等调控措施,小麦的籽粒品质将会得到不断改善。

Cyanobacterial toxins as allelochemicals with potential applications as algaecides, herbicides and insecticides

Cyanobacteria (“blue-green algae”) from marine and freshwater habitats are known to produce a diverse array of toxic or otherwise bioactive metabolites. However, the functional role of the vast majority of these compounds, particularly in terms of the physiology and ecology of the cyanobacteria that produce them, remains largely unknown. A limited number of studies have suggested that some of the compounds may have ecological roles as allelochemicals, specifically including compounds that may inhibit competing sympatric macrophytes, algae and microbes. These allelochemicals may also play a role in defense against potential predators and grazers, particularly aquatic invertebrates and their larvae. This review will discuss the existing evidence for the allelochemical roles of cyanobacterial toxins, as well as the potential for development and application of these compounds as algaecides, herbicides and insecticides, and specifically present relevant results from investigations into toxins of cyanobacteria from the Florida Everglades and associated waterways.

Microalgae as sources of carotenoids

Marine microalgae constitute a natural source of a variety of drugs for pharmaceutical, food and cosmetic applications-which encompass carotenoids, among others. A growing body of experimental evidence has confirmed that these compounds can play important roles in prevention (and even treatment) of human diseases and health conditions, e.g., cancer, cardiovascular problems, atherosclerosis, rheumatoid arthritis, muscular dystrophy, cataracts and some neurological disorders. The underlying features that may account for such favorable biological activities are their intrinsic antioxidant, anti-inflammatory and antitumoral features. In this invited review, the most important issues regarding synthesis of carotenoids by microalgae are described and discussed-from both physiological and processing points of view. Current gaps of knowledge, as well as technological opportunities in the near future relating to this growing field of interest, are also put forward in a critical manner.
