摘要
以30~200keV的氮或磷离子束对玉米、小麦、水稻、黑麦等植物种子进行离子注入的处理。在处理的当代种子及以后几代种子中均出现显著的生物效应变异,如发芽率、生长速度、植物株型等,染色体行为也出现异常。为了解诱变机理,以RBS测量并以TRIM程序计算了注入离子在植物种子内的分布,同时还测量了注入和未注入植物样品的PAL谱.对离子注入引起植物生物效应的机理和应用前景进行了讨论.
Seed of maize,rice,wheat,rye,etc,were implanted by nitrogen of phosphorus ions with energy of 30~200keV.The effects on germination percentage, growth speed and plant type were investigated.The abnormal character of chromosomes were found.The distributions of implanted ions in seeds were measured by RBS and calculated with TRIM program.The PAL spectrums of implanted and non-implanted samples by nitrogen ion were measured.The mechanism of biological effects induced by ion implantation and prospect for application were discussed.
