Abstract
[Objective] The study was to research the effect of Cu2+ and Zn2+ on seed germination and seedling growth of wheat.[Method] With wheat variety Boai 7422 as the material and culture with complete nutrient solution as CK.,the effects of Cu2+ and Zn2+ pollution with different concn.(5,10,25,50,125,250,500 mg/L)on seed germination,seedling growth and chlorophyll content in wheat were studied.[Result] Cu2+ with low conn(≤50 mg/L)and Zn2+ with low concn.(≤10 mg/L)could promote seed germination and seedling growth of wheat,Cu2+ with high concn.(50 mg/L)and Zn2+ with high concn.(10 mg/L)had inhibition on seed germination of wheat.Cu2+ and Zn2+ with low conn had no obvious effects on chlorophyll content in wheat seedlings.Cu2+ and Zn2+ with high concn.could decrease chlorophyll content in wheat seedlings,when Cu2+ and Zn2+ were 25 mg/L,the chlorophyll contents in wheat seedlings were lower 44.51% and 23.02% than that of CK resp,and when Cu2+ and Zn2+ reached 500 mg/L,the chlorophyll contents in wheat seedlings were 31.35% and 47.15% of that of CK resp.[Conclusion] Cu2+ and Zn2+ with low conn had no obvious effects on seed germination and seedling growth of wheat,but Cu2+ and Zn2+ with high concn.had inhibition on them.
