摘要:
采用室内水培法研究不同粒径、不同质量浓度纳米氧化锌(ZnO NPs)对水稻种子发芽和幼苗生物量的影响。结果表明,在500 mg/L质量浓度下,Zn2+和不同粒径ZnO NPs处理的水稻种子发芽率均在93%以上,与空白对照之间无显著差异;水稻幼苗的生物量生长受到抑制,地上部鲜质量减少幅度为14.29%~33.48%,根鲜质量减少幅度为35.81%~57.29%,根鲜质量均显著低于空白对照,Zn2+处理的地上部鲜质量、根鲜质量较低。由此可见,Zn2+比ZnO NPs对水稻幼苗生长具有更强的毒性。在不同质量浓度下,10 mg/L ZnO NPs处理的水稻苗长、根长分别提高了10.56%、32.26%,在100~500 mg/L ZnO NPs处理下,水稻根长、苗长分别下降了10.73%~16.83%、27.89%~4592%,且质量浓度越高,抑制作用越强。ZnO NPs对水稻根部的抑制作用大于苗部,ZnO NPs的粒径和质量浓度对水稻种子发芽无显著影响,低质量浓度能促进水稻幼苗的生长,而高质量浓度则会产生抑制作用。
