단풍나무속 수종의 (數種) 엽병 유관속지 (維管束枝) 변화형에 관한 연구
박광우,김삼식 ( Kwang Woo Park,Sam Shik Kim ) 한국산림과학회 1986 한국산림과학회지 Vol.73 No.1
This study was done to classify 15 species in the genus Acer through tracking of the changing shape of the vascular branch from the base part to the terminal part of petiole by the anatomical method. The basic vascular branches were 3 ea, except A. mandshuricum 3-4 ea. The vascular bundle was separated, moved and connected from the base part to the terminal part of petiol, the number of separated vascular branch was 11-32 ea., the number of connected vascular branch was 0-17 ea.., and the ratio of the separated vascular branch to the connected was 0.00-8.00. The maximum number of vascular branch in No, 39 of cross section part was observed in 12 species; A. ginnala and A. buergerianum were No. 11, A. truncatum and A. platanoides were No. 13, A. saccharium was No. 26. The number of the connected vascular branches with the main vascular branch were 0-6, while the number of the separated vascular branch were 0-7. On the ratio of separation to connection of the base vascular branch; $quot;A$quot;, $quot;B$quot; and $quot;C$quot;, the symmetrical shapes on the basis of $quot;B$quot; were A$gt;B$lt;C and A=B=C shape, the asymmetrical shape were A$lt;B$gt;C, A$lt;B$lt;C and A$gt;B$gt;C shape. The classical groups by the development of main vascular branch formation were obtained 7 groups of $quot;a$quot; through $quot;g$quot; shape. Especially, A. negundo and A. saccharinum were shown to have central vascular branches with unique changing patterns.

This study was intended to identify 17 taxa. (5 varieties and 12 species) of the genus Acer in Korea on the basis of the shapes of stomata, the type of trichome on the different part of leaves, the shapes, arrangement and number of stele in cross section of petiole. The results obtained were summarized as follows; 11 The shape of guard cells of stomata in the genus Acer was anomcytical, and the size of the cells ranged from 10.25 to 21.00 μ in length and from 7.57 to 11.83 μ in width. 2) Eleven types of trichome on the leaf in the genus Acer were found; pilose, sericeous, velutinous, woolly, glabrate, puberulent, bladder hair, hispid, hirsute and uncinate. This characteristics also established a good criterion for identification of species. 3) The stele of petiole in the genus Acer was characterized by eustele and atactostele with polybranch, and the six groups of the shape of numerical change of stele; B$gt;M=T, B$lt;M=T, B=M=T, B$gt;M$lt;T, B$lt;M$lt;T, B=M$lt;T were found at Three parts of petiole, where, B : the number of ramified stele at the base part of petiole, M : the number of ramified stele at the middle part of petiole, T : the number of ramified stele at the terminal part of petiole. 4) The shapes of petiole in cross section of the genus Acer were a, b, c, d, e, f and g shape. The $quot;b$quot; shape appeared in 7 species and had the hightest appearance frequency. The $quot;a$quot; and $quot;c$quot; shape appeared both in 4 species. The $quot;g$quot; shape appeared in 3 species. And the $quot;d$quot;, $quot;e$quot; and $quot;f$quot; shape appeared in 2 species. In conclusion, it was possible to identify 17 taxa. of the genus Acer in Korea by the shape of stomata, trichome and the shape, arrangement, and number of stele in cross section at three parts of petiole.

This study was identified 6 species of the genus Acer in Korea by the method of thin layer chromatography on lipids in heart wood, and researched affinity among the species for the characteristics of color reaction. The results were summarized as follows; 1) Total-lipid in heart wood of the six species was 4.39%, mean free-lipid was 2.85% and mean bound-lipid was 1.54%. 2) All the six species; A. ginnala, A. mono, A. negundo, A. palmatum, A. saccharinum and A, triflorum were identified by the characteristics of color reaction. Judging from the color reactions, A. palmatum and A. triflorum seem to be closer than other species.
