A practical and efficient synthesis of 1,4-dideoxy-1,4-imino-D-arabinol and its partially protected derivatives has been described via the key intermediate with
Amphiphilic block copolymers composed of D,L-lactide, trimethylene carbonate and the methoxy poly (ethylene glycol) (PETLA) were synthesized with ring-opening c
本研究利用亲本Jagger与2174通过重组自交构建的96份RILs群体,并设计不同温度和贮藏时间处理,对小麦穗发芽抗性进行了整穗发芽率、籽粒发芽率、α-淀粉酶活性三个指标的鉴定,结合皮色对小麦穗发芽抗性及α-淀粉酶活性进行分析,并在全基因组范围内检测小麦种子抗穗发芽相关QTLs,以期为小麦抗穗发芽育种与栽培提供理论依据。试验主要结果如下:1、穗发芽抗性的三个指标鉴定结果表明,整穗发芽率、籽粒发芽

水稻是世界重要的粮食作物之一,由子囊菌(Magnaporthe oryzae)引起的稻瘟病是世界性的水稻病害,广泛分布于水稻栽培的国家和地区,严重影响水稻的产量和稻米的品质。发掘水稻
在朱新礼看来,上游是一个商业蓝海,而且将大有作为,这对企业、对果农、对农村的贡献将远远大于汇源这个品牌本身.rn朱新礼认为这正是汇源的机会所在, “没有上游怎么保证下游
马铃薯(Solarium tuberosum L.)是全球仅次于小麦、玉米和水稻的第四大栽培作物;我国于上世纪90年代中期马铃薯栽培面积和总产量超越欧盟成为马铃薯第一生产大国。作为今后我国最具增产和发展潜力的栽培作物之一,近年来马铃薯生产与产业化发展受到国家和各级地方政府高度重视。干旱是一个世界性的问题,导致的减产可超过其它因素所造成减产的总和。因此研究马铃薯对干旱胁迫的响应、揭示其耐旱性的生理遗
After preparing the precursor by a liquid precipitation method,a series of tin-zinc composite oxides with different components and structures were synthesized a
