영문 초록

Morphological characteristics of leaves, trichomes and acorns were investigated in 6-year-old artificial hybrids of Q. aliena × Q. mongolica var. crispula and Q. serrata × Q. mongolica var. crispula. Leaf shapes of Q. aliena × Q. mongolica var. crispula F₁ were obovate and resembled to that of Q. aliena. But several characters including the size of leaf and petiole and the shape of leaf base resembled to those of Q. mongolica var. crispula. In F1 hybrids, small stellate hairs distributed sparsely on the abaxial surface and their lay length was intermediate between both parents. There were no big differences on characters of nuts and cupules between both parents and F₁ hybrids. Leaf shapes of Q. serrata × Q. mongolica var. crispula F₁ were obovate-elliptic, and the leaf shape and leaf base and the length of petiole resembled to those of Q. mongolica var. crispula, but leaf size and serration resembled to those of Q. serrata. The number of serration in a leaf was intermediate between both parents. Small stellate hairs distributed sparsely and large single hairs were mixed on the reverse side of leaves. there were no big differences on the number and size of stellate hairs between F₁ hybrid and Q. serrata. It is able to distinguish F₁ hybrids from both parents by the size leaf size and shapes, leaf base and serration, petiole length and trichome type in the leaf.
