纳米氧化锌和纳米氧化硅对水稻种子萌发的影响
Effects of nano zinc oxide and nano silicon dioxide on rice seed germination
摘要
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,germi-nation 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 ex-cessive concentrations of nZnO and nSiO2 may cause a countereffect.The effect of adding the same mass concentra-tion 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 nZ-nO or nSiO2 was more favorable for seed germination of the tested rice varieties.关键词
