【摘要】 报导了用扫描电子显微镜-能量色散X射线谱仪(SEM-EDS)测量了能量为20keV的Ti+注入干棉花和花生种子的深度-浓度分布。测量结果表明:该分布是带有长尾巴的非对称高斯分布,对于棉花和花生种子,Ti+的最大穿透深度分别达到21μm和36μm。最后讨论了低能离子注入使植物种子后代发生变异的机理.更多还原

【Abstract】 The paper presents the depth-concentration distribution of 20keV Titanium ions implanted into dry seeds of cotton and peanut measured by SEM-EDS. The measured results show that depth-concentration distribution is a non-symmetry Gaussian distribution with a long tail and maximum penetration depths of 20keV Titanium ions implanted into seeds of cotton and peanut are about 21 μm and 36μm .The mechanism of the induced mutation to the plant progeny is discussed.更多还原
