世界黄麻,红麻纤维与制品的生产和贸易

１００多年以来，世界黄麻生产久兴不衰，但近１０多年以来，由于合成纤维和集装箱运输取代了部分麻袋，国际市场上稻米价格高，农民将部分麻田改种水稻；以及世界市场上黄麻供需形势的变化，价格不稳定，导致黄麻种植面积、纤维和制品的产量均有所下降，本文报道近１０年来世界黄麻、红麻种植面积、纤维和制品的生产、进出口和价格等情况。

稻麦双晚对病虫草发生的影响及解决措施

随着早熟晚粳、中熟晚粳广泛种植,水稻轻型省力栽培方式旱直播的推广,病虫也发生了变化,成熟期显著推迟,下茬无法在适宜播期种植,影响粮食丰产稳产。提出筛选早熟当家品种、大力推广机插秧、加大粮食烘干设备的投入、合理施肥、精准植保等对策。     

Sorghum and millet phenols and antioxidants

Sorghum is a good source of phenolic compounds with a variety of genetically dependent types and levels including phenolic acids, flavonoids, and condensed tannins. Most sorghums do not contain condensed tannins, but all contain phenolic acids. Pigmented sorghums contain unique anthocyanins that could be potential food colorants. Some sorghums have a prominent pigmented testa that contains condensed tannins composed of flavan-3-ols with variable length. Flavan-3-ols of up to 8–10 units have been separated and quantitatively analyzed. These tannin sorghums are excellent antioxidants, which slow hydrolysis in foods, produce naturally dark-colored products and increase the dietary fiber levels of food products. Sorghums have high concentration of 3-deoxyanthocyanins (i.e. luteolinidin and apigenidin) that give stable pigments at high pH. Pigmented and tannin sorghum varieties have high antioxidant levels that are comparable to fruits and vegetables. Finger millet has tannins in some varieties that contain a red testa. There are limited data on the phenolic compounds in millets; only phenolic acids and flavones have been identified.

加强闽台科技合作交流发展我省甘蔗业

概述了海峡两岸农业交流与合作的现状,提出了应该共同呼吁尽快实现两岸“三通”,开放农业生物技术图书期刊资料交流以及开放生物学科方面网络的思路,以便为农业交流与合作的顺畅开展打好基础,并寄希望能够就糖蔗、果蔗以及甘蔗笋等方面的研究与开发到台湾学习取经,开展学术交流或与台湾同行共同开展研究,为我省甘蔗业的发展作出贡献。     

种子加工、检验理论与技术现状及思考

种子加工及检验是种子向市场流通的关键，是商业化育种中赋予种子商品属性不可或缺的环节。种子加工、检验理论与技术的研究是完善种业产业链、实现规模化商业育种、夯实“育繁推一体化”种业科学的重要一环。中国的种业科学技术体系正在形成与完善之中，受制于行业发展水平，种子加工及检验理论与技术相对薄弱。本文回顾了种子加工及检验理论与技术研究发展历程，提出了完善中国种业科学发展的策略与建议。围绕种业发展的需要，在做好品种优质化繁育的基础上，分析种子加工及检验理论与技术的新方向和新需求，加强种业应用性研究，建立先进的种子质量检验体系，研制适合现代种业发展需求的种子加工设备，打造种子加工产业标准化生产体系，完善种业科学技术学科建设，促进种业产业持续健康发展。     

大豆几种常见病虫草害的诊断与防治

1大豆花叶病毒病 大豆病毒病（Soybean Mosaic Virus,SMV）是世界性病害之一。我国东北地区已鉴定的有5种,即大豆花叶病、顶枯病、蚕豆萎蔫病、南方菜豆花叶病、花生条纹病毒。其中大豆花叶病在全国大豆主要产区都有发生,十分常见。

Tuber and starch quality of wild and cultivated potato species and cultivars

Summary Between 1993 and 1998 205 different potato cultivars and 1220 accessions/genotypes of wild and cultivated potato species from the IPK Genebank Gatersleben were evaluated. Parameters interesting for starch isolation and especially for the use of starch were determined. Altogether, there was a higher variability in wild potato species than in cultivated potatoes for all characteristics investigated: dry matter content, starch content, protein content, amylose content and mean particle diameter of starch granules.     

Yield and quality of winter and spring triticales for forage and grain

In field experiments conducted over 2 years in Mediterranean conditions, five winter and five spring triticales were evaluated for forage and grain production in the same cropping season. The experiments had two treatments, namely harvesting for grain only, and dual-purpose forage and grain production. In the latter treatment, forage was cut when the first node was detectable (Zadoks' stage 31), without removing the apical meristems. Grain was harvested when ripe (Zadoks' stage 92) in both cut and uncut plots.
Environmental conditions affected grain production and protein content more than forage yield and quality. Winter triticales yielded about 43% more forage than spring types, but after forage removal the spring types yielded about 36% more grain than winter triticales.
Reductions in grain yield after clipping were more pronounced in winter (32%) than in spring (19%) types. Forage crude protein content was significantly higher in the spring types studied (24.6%) than in the winter types (23.5%), the opposite being true for fibre content (20.7 and 21.6% respectively). Grain crude protein content did not differ between grain and dual-purpose treatments, but was higher in the spring triticales (12.8%) than in the winter types (11.9%). There was more variability for the measured traits within the winter triticales studied than within the spring types.
