Bioeffects of Low Energy Ion-Beam Implantation and Vacuum Treatment on M1 Arabidopsis Thaliana

Vacuum treatment and ion-beam bombardment are two major processes in the low energy ion-beam implantation. To accurately study the contributions of these two major factors to the bioeffects separately, the M1 generation variation of Arabidopsis thaliana with ion-beam implantation and vacuum treatment were compared through a series of key plant development parameters including morphological observation, biochemical assay and RAPD （random amplified polymorphic DNA） analysis. The results showed that ion-beam implantation had obvious effect on almost all of these parameters, and the vacuum treatment had some impacts on several morphological parameters such as the bolting time and the length of the primary stem. Taking the results together, the indication is that vacuum treatment has some slight contributions to the bioeffects of ion-beam implantation while ion-beam bombardment itself is the major creator of the bioeffects.     

等离子电视机的基础知识问与答

什么是等离子电视?它和我们普遍使用 的CRT电视机有何异同? 等离子电视的英文些缩写为PDP,台 湾又叫“电浆电视”。简单地说,PDP 是利用气体电离后产生的紫外线来 激发红、绿、蓝三种颜色的荧光粉,使其发光形成影像的一种新型电视机/显示设备。
