摘要: 以水稻品种葛68优623、武大优1号、稻花香二号、空育131的种子为供试材料,对比了添加10、100、200、500、1 000 mg·L-1的纳米氧化锌(nZnO)或纳米氧化硅(nSiO2)与不加纳米材料的对照下水稻种子吸水率、发芽率、发芽势、萌发时间、发芽指数、根长、芽长、鲜重的变化。结果表明:添加适宜质量浓度的nZnO和nSiO2可以增加水稻种子的吸水率、发芽率、发芽势、发芽指数、地上部鲜重、根鲜重、芽长和根长,缩短其萌发时间,但是过高浓度的nZnO和nSiO2可能会产生反作用。添加相同质量浓度的纳米材料对不同品种水稻种子萌发的影响并不完全相同,综合对比发现,武大优1号对两种纳米材料的响应较为明显。100~200 mg·L-1的nZnO和nSiO2处理对供试水稻品种的种子萌发较为有利。

Abstract:

In the present study, the seeds of rice cultivars Ge68you623, Wudayou No. 1, Daohuaxiang No. 2 and Kongyu131 were used as test materials, and the effects of addition of 10, 100, 200, 500, 1 000 mg·L-1 nano zinc oxide (nZnO) or nano silicon dioxide (nSiO2) on water absorption rate, germination rate, germination vigor, germination time, germination index, root length, shoot length and fresh weight of rice seeds were explored by comparison with the control without addition of nano materials. It was shown that the addition of appropriate mass concentrations of nZnO and nSiO2 could increase the water absorption rate, germination rate, germination vigor, germination index, fresh weight of shoot and root, shoot length and root length of rice seeds, and shorten the germination time, but excessive concentrations of nZnO and nSiO2 may cause a countereffect. The effect of adding the same mass concentration of nanomaterials on the seed germination varied within rice varieties. By comprehensive comparison, it was found that the response of rice variety Wudayou No 1 was obvious to the two nanomaterials. Addition of 100-200 mg·L-1 nZnO or nSiO2 was more favorable for seed germination of the tested rice varieties.
