摘　　要：N+ 离子注入甜菜种子后 ,观察 M2 代生物效应 ,在做鉴定抗病性试验时 ,发现产量均比 M1 代减产 ,含糖率均比对照提高 ,提高 0 .97～ 2 .76度 ;抗病性对照 (改 6 )褐斑病指数为 1级 ,4份参试材料的褐斑病指数为 0 .5级 ,比对照降低 0 .5级。在做早熟性试验时 ,产量同样比对照减产 ,但含糖率均比对照提高 ,提高 1.47～ 3.0 8度 ,观察试验结果 。bserving the biological effect 0n M 2 generation and appraising antivirus find that the output is reduced compared with M 1 generation ,whereas the sugar rate is enhanced compared with CK , After N + ion implantation into sugar beet seeds; The sugar enhancement rate is 0.97-2.76 degrees; The speckle index is classification 1 on antithesis (Improved 6). Test on four exponents is classification 0.5, equally reduced compared with CK. Test on prematurity also finds that yield is reduced , too, but sugar rate is enhanced , which is 1.47-3.08 degrees . The observation of test result shows a sign that there is trend of pre collectivity in sacchariferous accumulation.
