| 中文摘要: |
| 为研究金属型纳米颗粒对蔬菜种子发芽性能和幼苗生长的影响，于2017年7月采用种子发芽试验，探究了不同浓度（0、50、100、200、500、700、1 000 mg·L-1）下纳米氧化锌颗粒（ZnO NPs）和硫酸锌（ZnSO4）处理对樱桃萝卜（Raphanus sativus L.）和小白菜（Brassica chinensis L.）种子发芽性能及幼苗生长的影响。结果表明：不同浓度ZnO NPs或ZnSO4处理下两种蔬菜作物的发芽率与对照处理相比均无显著差异（P>0.05），而两种蔬菜的生物量则均受到抑制。ZnO NPs及ZnSO4处理对两种蔬菜根长的抑制作用强于芽长。ZnO NPs对两种蔬菜种子根长的抑制率比ZnSO4更大，且抑制率均随着处理浓度的升高而增加，在1 000 mg·L-1时最高，达到98%。而ZnSO4对两种蔬菜芽长的抑制作用强于ZnO NPs。研究表明，尽管ZnO NPs和ZnSO4对两种蔬菜发芽率无显著影响，但二者均在一定程度上抑制了两种蔬菜根长和芽长。 |

| To study the effects of metal-based nanoparticles on the germination and growth of vegetable seeds, an experiment was conducted in July 2017 to explore the effects of different zinc oxide nanoparticles(ZnO NPs)and zinc sulfate(ZnSO4)treatments(0, 50, 100, 200, 500, 700, and 1 000 mg·L-1)on germination performance and seedling growth of Raphanus sativus L. and Brassica chinensis L.. Results showed no significant difference in the germination rate between the two vegetable crops under different ZnO NPs and ZnSO 4 treatments(P>0.05)when compared with the control; while the biomass of both vegetables was inhibited. ZnO NPs and ZnSO4 inhibited the root length of both vegetables more than their shoot length. The inhibition rate of ZnO NPs on root elongation of both vegetables was greater than that of ZnSO4, while it increased with an increase in treatment concentration, reaching up to 98% at 1 000 mg L-1. However, ZnSO4 inhibited shoot growth of both vegetables much more than ZnO NPs. The results revealed that although ZnO NPs and ZnSO4 had no significant effect on the germination of both vegetables, they both inhibited the root length and shoot length to some extent. |
