摘要： 利用离子注入技术,将不同能量、不同剂量的铁离子和铝离子分别注入一串白种子,通过分析萌发率、突变率及株高、冠幅、花序长、叶绿素相对含量等指标,探讨不同离子注入处理对一串白生物学效应的影响。结果表明,对一串白种子萌发率表现出抑制作用,对叶色改变的影响均为正向突变;虽然6个处理对一串白植株冠幅影响差异不显著,但对株高、花序长和叶绿素相对含量的影响差异极显著,其中Ⅱ号处理(70keV-Fe³⁺-5×10¹⁵ions⁄ cm²)的株高均值最小为15.85cm、Ⅰ号处理(70keV-Fe3+-1×10¹⁶ions⁄cm²)花序长和叶绿素相对含量均值最高,分别为8.78cm和45.19。

Abstract: Using the technology of ion implantation,the Fe³⁺ions and Al³⁺ ions with different energy and dose were implanted to Salvia splendens var. alba seeds. By analysing the indexes including germination rate,mutation rate,plant height, crown width, verticillaster length and chlorophyll relative content,the influence of different ion implantation treatments about biological effect of Salvia splendens var. alba was discussed. The results revealed that the six treatments inhibited the germination rate of Salvia splendens var. alba seeds while caused forward mutation on the leaf colour. Although the crown width of Salvia splendens var. alba was not significantly affected by the six treatmenu, the plant height, verticillaster length and chlorophyll relative content were markedly affected. Among these treatments, the highest average minimum average plant height of treatment (70 keV-Fe³⁺-5×10¹⁵ions/cm²) was 15.85 cm,the verticillaster length and chlorophyll relative content of I treatment (70 keV Fe³⁺-1×10¹⁶ ions/cm²) were 8.78 cm and 45.19 respectively and 45. 19 respectively.
