紫鸭跖草细胞中铜的分配和化学形态特征研究(英文)

[Objective] The aim of this study was to reveal the mechanism of Cu2+ hyper-accumulator in Setcreasea purpurea Boom from the angle of distribution characteristics and binding form of Cu2+ in tissue cells.[Method]The distribution characteristics of Cu2+ in subcells of Setcreasea purpurea Boom was studied by the technique of differential centrifugation,and the binding form of Cu2+ in roots and leaves of Setcreasea purpurea Boom was also investigated by the sequential chemical extraction method and the enzymolysis method.[Result]Cu2+ in roots mainly distributed in the cell wall which is accounting for one third of the Total Cu2+ in roots,while Cu2+ in leaves mainly distributed in the chloroplast which is accounting for a quarter to the Total Cu2+ in leaves.Under the high concentration of Cu2+ or the extended treatment duration,the translocation of Cu2+ in root cells into the cell wall increased but the translocation of Cu2+ in root cells into the plastid decreased,while the translocation of Cu2+ in leaf cells into the chloroplast increased but the translocation of Cu2+ in leaf cells into the cell wall decreased.Cu2+ in leaves was mainly combined with amino acid,small molecular polymeric pigments,protein and polysaccharide,while Cu2+ in roots was mainly combined with cell wall substances such as cellulose and membrane-bound protein.[Conclusion]The distribution characteristics and binding form of Cu2+ in cells is possibly one of the dominant mechanisms for Cu2+ hyper-accumulator in Setcreasea purpurea Boom.     

怒江野生铁核桃树改造技术

怒江州历史上就有核桃种植,野生核桃资源十分丰富,据2005年调查,怒江州核桃树超过了400万株,且大部分为野生铁核桃,主要分布在贡山、福贡、泸水、兰坪4县。由于铁核桃利用价值低,难以让人们接受,因此没有形成商品,其经济价值较低。利用这些自然资源,我们通过引进外地优良核桃品种接穗,将其嫁接改造成具有较高经济价值的优质泡核桃,结合后期管理,3～5年即可开花结实。     

养猪户购用饲料的几个误区

误区一:饲喂后猪体皮毛光亮就是上等饲料.一些饲料厂家为了迎合养猪户这种需求,超大剂量使用有机砷制剂,猪采食后皮肤光亮发红.砷制剂有致癌作用,滥用会造成环境污染和给人体健康带来不良影响.
