基于地理自然致灾和人工胁迫致灾试验、大田灾情调查、历史灾情反演、文献查阅等集成构建技术,分别建立了香蕉辐射型、平流型寒冻害等级指标及灾害损失指标,并规范了香蕉寒冻害等级下受害表观症状。这一结果对开展香蕉寒冻害动态监测预警与灾损量化评估等专项气象服务,以及开展香蕉寒冻害灾情调查和实施防寒减灾措施等均有积极的指导意义。
研究了4个水稻品种返回式卫星搭载和60Co-γ射线辐照两种条件下SP2(M2)和SP3(M3)的稻米品质差异性。研究结果表明,空间诱变后代稻米品质性状发生不同程度的变异,其变异幅度和方向因品种或性状不同而异;空间诱变后代的胶稠度、垩白粒率和垩白度主要为正向变异,而直链淀粉含量多为负向变异,其变化趋势与γ射线辐照后代相似,但前者更有利于创造米粒长宽比大、糊化温度低和垩白小的变异株系。稳定性分析显示,...

辐照对卷烟中烟草特有亚硝胺含量的影响
卷烟 辐照 烟草特有亚硝胺 液相色谱/质谱联用
2013/9/5
以3种市售卷烟为材料,采用0、5、10、20和30kGy 5个剂量对其进行辐照处理,研究了辐照对卷烟中TSNAs含量的影响,主要采用液相色谱/质谱联用的方法,检测了N'-亚硝基降烟碱(NNN)、N'-亚硝基新烟碱(NAT)、N'-亚硝基假木贼碱(NAB)和4-(N-甲基亚硝胺基)-1-(3-吡啶基)-1-丁酮(NNK) 4项指标的含量。研究发现:辐照可以降低卷烟主流烟气和烟丝中TSNAs的含量,但...
