将辽粳294水稻种子和不同浓度的碳纳米管共培养，对水稻种子萌发和幼苗生长情况进行观察，研究碳纳米管对水稻种子萌发和幼苗生长的影响。结果表明，适当浓度的碳纳米管(50~100滋g/mL)促进了水稻种子发芽、根系生长和根系活力。当碳纳米管浓度增加到150滋g/mL时，根系活力较100滋g/mL时降低，但仍略高于对照。说明较低浓度的碳纳米管可以促进水稻种子发芽、根系生长和根系活力，而高浓度的碳纳米管则可能产生毒害作用。

Rice seeds were co-cultured with carbon nanotubes of different concentrations. To explore the effects of carbon nanotubes on rice seed germination and root growth, the rice seeding growth was germination percentage rate, length of seed-ing stem and root observed including. The results showed that the rice seed germination and root growth were promoted by carbon nanotubes with appropriate concentrations (50~100μg/mL). When the concentration increased to 150μg/mL, the root length, root activity and stem length decreased in comparison with the value of 100μg/mL, slightly higher than that of the control. The root and stem lengths were shorter than that of the control. It is indicated that carbon nanotubes can promote the rice seed germination and root growth at low concentrations, and may have toxic effects at high concentrations.
