摘要:
以黔威3号苦荞为试验材料,研究铝(Al)胁迫对苦荞种子萌发及幼苗生长特性的影响,以探讨苦荞对铝的耐受性。结果表明,与对照相比,低浓度的AlCl3溶液(100 μg/mL)促进了苦荞种子的萌发,而较高浓度的AlCl3溶液(1 600~6 400 μg/mL)则在一定程度上抑制了其种子的萌发,延缓了种子萌发进程,但是仅在6 400 μg/mL AlCl3浓度下对苦荞种子最终萌发率的抑制作用达到显著水平(P<0.05)。与对照相比,100 μg/mL AlCl3溶液对苦荞植株的株径、株高、根长、分枝数及叶面积产生促进作用,且对株高、叶面积的促进作用达到显著水平(P<0.05),而400~6 400 μg/mL AlCl3溶液则对相应指标产生抑制作用,且在6 400 μg/mL浓度下对株高及叶面积的抑制作用达显著水平(P<0.05)。与对照相比,除100 μg/mL浓度处理外,AlCl3溶液对苦荞的生物量积累和分配不产生显著影响。由以上结果可见,苦荞对铝胁迫具有一定的耐受性。
