Abstract

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.

Key words: rice, nano zinc oxide, nano silicon dioxide, seed germination, germination rate
