Abstract
[Objective] The purpose was to study the effects of different concentration of Ca2+ and Cu2+ on seed germination of 03132-6,a new winter wheat variety,and provide a theoretical basis for physiological research on salt resistance of wheat and its application.[Method] The concentration of Ca2+ and Cu2+ were 0.05%,0.10% 0.15%,0.20%,0.25%,0.30% respectively.[Result] The results showed that under the same ion,its different concentrations had different effects on wheat seeds germination,and under the same concentrations,different ions also had different effects on wheat seeds germination.The Cu2+ had significant influences on wheat seeds germination and that the effects of Ca2+ was lower than Cu2+.When the concentration of Ca2+ was less than or equal to 0.15%,the germination energy,germination percentage and amylase activity all increased,while when its concentration was more than or equal to 0.20%,those all decreased.The germination energy,germination percentage and amylase activity decreased significantly when the concentration of Cu2+ was higher than or equal to 0.05%.[Conclusion] 0.05%-0.30% Cu2+ the germination of wheat seed;0.05%-0.10% promotes the germination of wheat seed,while 0.15%-0.30% Ca2+ restrains the germination of wheat seed.
