Abstract:Inbred line of maize plants of five genotypes were treated with five Zn solution to test their nutritional characters. The result indicated there was different sensitivity in five genotypes to different Zn concentration . When Zn concentration was 10^-7mol/L, the maize seedling grew very well, it is the most suitable Zn concentration to maize growth. The Zn concentration in which maize seedling grew worst was 10^-9mol/L. There is different effect to different solution Zn concentration among five inbred line of Maize . The solution Zn concentration has obvious effect on the growth of shoot , and no significant effect on root. SN-11 is Zn sensitive inbred line of maize. 178, XingK36, Chang7-2 are middle sensitivity genotypes. LuYuan92 is close to Zn efficient genotype.
