| Abstract: | The contents of fructose,sucrose and total soluble sugar in stem and leaf during the stage from the embryo formation to the full filling grain were measured with five spring wheat cultivars(lines) divergent significantly in kernels per ear and grain degenerating ratio,reveal the influence of the change of sugar content in different organs to the degenerating ratio of the juvenile embryo during the embryo formation in spring wheat.The results showed that the variation range of sucrose and total soluble sugar in stem and leaf,that of fructose and sucrose in flag leaf were relevant to the juvenile embryo degenerating ratio during the stage from the embryo formation to the full filling grain.The variation range of those sugars was found to be larger in the cultivars with lower embryo degenerating ratio. |
| Keywords: | spring wheat juvenile embryo sucrose fructose total soluble sugar |
