The Effect of Graphene on Seed Germination of Annual Herbaceous Plants under Salt and Drought Environments
摘要
Abstract
In order to study the effect of graphene on seed germination of annual herbaceous plants in salt-drought environment of Haloxylon ammodendron plantation,this study took 5 typical annual herbaceous plants(3 species of chenopodium,Grubovia dasyphylla,Halogeton arachnoideus,Agriophyllum squarrosum and 2 species of gramineous plants,Setaria viridis and Chloris virgata)under Haloxylon ammodendron plantation in desert oasis transitional zone of Hexi Corridor as re-search subjects,and the effects of different concentrations of graphene on seed germination of annual herbaceous plants under salt stress,drought stress and combined salt and drought stress.The results showed that for salt stress treatment,the application of 10 mg/L and 20 mg/L graphene had the best effect on seed germination of Halogeton arachnoideus and Chloris virgata,and the application of 20 mg/L and 30 mg/L graphene had the best effect on seed germination of Grubovia dasyphylla,Agrio-phyllum squarrosum and Setaria viridis.For drought stress treatment,20 mg/L and 30 mg/L gra-phene could basically alleviate the effects of drought stress on 5 annual herbs.For the combined salt and drought stress treatment,10 mg/L and 20 mg/L graphene had the best effect on the seed germi-nation of Grubovia dasyphylla,Halogeton arachnoideus and Agriophyllum squarrosum.The results of normalization analysis showed that graphene had the best seed germination effect on the annual grasses of the gramineae family under salt stress and combined salt and drought stress,and the best seed germination effect on the annual grasses of the chenopodium family under drought stress.In summary,the application of 20 mg/L graphene had the best effect,and was generally conducive to promoting seed germination of annual herbs under salt and drought environment.关键词
