摘要
利用兰州重离子加速器国家实验室(HIANLL)提供的100MeV/u碳离子束对甜高粱品种BJ0601和BJ0602进行了不同剂量的辐照处理,并用SPSS13.0软件分析了碳离子束辐照剂量和甜高粱主要性状节间数、株高、茎粗、含糖量及单秆重的相关性,试验结果表明:不同的辐照剂量对甜高粱节间数、株高、茎粗、含糖量及单秆重产生了明显的影响,表现出不同程度的相关性。另外,早熟突变株BJ0601-1M2代各节的平均含糖量高于BJ0601,说明碳离子束辐照可能引起甜高粱含糖量的提高。
To investigate the influence of carbon ion irradiation on important agronomic characters of sweet sorghum, dry seeds of Sweet Sorghum BJ0601 and BJ0602 were irradiated by 100 MeV/u ^12C^+6 ion beam to different doses at Heavy Ion Accelerator National Laboratory in Lanzhou (HIANLL). When matured, the main traits of sweet sorghum were measured. The correlation coefficient of five main agronomic characters, i.e. number of node, plant height, stalk diameter, sugar content and stem weight per plant, were analyzed using the SPSS13.0 software. The results indicated that the obvious influence of sweet sorghum irradiated by carbon ion beam was observed. In addition, the correlation of main traits was studied. This study may provide rudimental data to select novel variety of sweet sorghum suited for fuel ethanol production. In addition, the average of sugar content of early mutant BJ0601-1 is higher than BJ0601 in M2, and the sugar content of sweet sorghum may be improved by carbon ion beam irradiation.
