Abstract:

？通过温室盆栽试验,研究了低钾(0.01mmol·L-1)和正常钾(2.5mmol·L-1)水平对NaCl胁迫下罗布麻(Apocynumvenetum)生长和离子吸收分配的影响。结果表明,随着介质中NaCl浓度的增加,罗布麻的根、茎、叶的生物量和株高呈下降趋势;但相同浓度NaCl处理下,低钾和正常钾之间无显著差异(P>0.05)。罗布麻各器官中Na+含量随介质NaCl浓度的增加显著上升(P<0.05),叶中上升幅度明显大于根和茎;叶和茎中K+随介质NaCl浓度的增加显著下降,但仍维持较高水平,根中K+浓度能保持稳定;低钾和正常钾水平下,与无盐胁迫(对照)相比,50mmol·L-1NaCl处理植株叶中K+浓度无显著变化。在对照条件下,罗布麻体内积累大量K+,其叶中K+浓度是Na+的15倍多。可见,增强K+的选择性吸收和运输,保持叶部较高的K+含量和K+/Na+比是罗布麻适应盐逆境的重要生理机制。
