The embryo oil content, size, and weight of seeds from the two yellowhorn lines at different developmental stages. a Seeds and embryos of yellowhorn at four development stages. (Picture cited from Wang et al. [12]). b Embryo oil contents in seeds from the two yellowhorn lines at four development stages. (Data from Wang et al. [12]). c Transverse diameter of HO and LO seeds at four developmental stages. d Longitudinal diameter of HO and LO seeds at four developmental stages. e Lateral diameter of HO and LO seeds at four developmental stages. f Hundred-grain weight of HO and LO seeds at four developmental stages. Error bars indicate standard deviations for three biological replicates. ** and * indicate significant differences between the lines at the same developmental stage based on a Student’s T-test at P < 0.01 and P < 0.05, respectively
