From two to five-year-old hybrids of Q. serrate ${\times}$ Q. dentate; Q. dentata ${\times}$ Q. serrata, Q. dentate ${\times}$ Q. mongolica var. crispula, and Q. dentata ${\times}$ Q. aliena, intermediate-size of stellate hairs or both types of their parents have been observed. Especially the hybrids between Q. serrate and Q. aliena and Q. aliena and Q. serrate had both types of their parents. The trichomes of the hybrids between Q. fabri and Q. serrate was the characteristics of Q. serrate. It was possible to identify two to five-year-old of interspecific hybrids based on trichome characteristics.
