정우규(Woo Gyu Jeong),김정석(Chung Suk Kim) 한국식물학회 1987 Journal of Plant Biology Vol.30 No.1

The epidermal structure and stomatal types in vegetative and reproductive organs of three species of Bryophyllum(B. crenatum, B. diagremontian, B. tubiflorum) were described. The epidermal cells were polygonal, isodiametric, and rectangular in the leaves and stems, and elongated cells in the stamens, styles, and ovaries. These cells were commonly thick, and arched or sinuous in the leavas, epiphylous buds, petals and ovaries. They were straight in the stems, petioles, pedicels, and peduncles. In both vegetative and reproductive ogans, the subsidiary cell walls were commonly thin and mostly arched in all the organs. The great majority of the mature stomata in all the organs were helicocytic type with a helix of four to six subsidiary cells. The mature stomata varied from organ to organ with regrad to the number and arrangement of subsidiary cells. The ontogenetic type of stomata in all the organs was mostly helico-eumesogenous type. This type was subdivided into three subtypes such as parahelico-eumesogenous, anomohelico-eumesogenous, and diahelico-eumesogenous stomata on the basis of the division angle of the guard mother cell. Sometimes, the aniso-eumesogenous type was found in various organs. This type was subdivided into three subtypes such as paraniso-eumasogenous, anomoaniso-eumesogenous, and dianiso-eummesogenous stomata. The tetra-eumasogenous and duplotetra-eumesogenous types were rarely found;the former in the leaf of B. crenatum and the latter in the leaf of B. diagremontiana. Anomomeristic patterns in the mesogenous categorry of stomatal types was observed in a few organs of all the materials. A new stomatal type with tetra-eumesogenous stoma within a girdle of three subsidiary cells of aniso-eumesogenous in the leaf of B. diagremontiana was firstly observed in the vascular plants. This stoma was termed the cotetra-aniso-cumesogenous type. Anormal stomata such as aborted stomata, single guard cells, stoma with a constricted part in the middle of large guard cells, and arrested stomata were found in the various organs of all the materials.

정우규(Woo Gyu Jeong),김진성(Jin Sung Kim),김정석(Chung Suk Kim),성민웅(Min Wung Sung) 한국식물학회 1987 Journal of Plant Biology Vol.30 No.2

This study was carried out to investigate the epidermal structure, the stomatal types, the ontogeny of stomata in various parts of each organ of K. blossfeldiana, K. kewensis, and K. tometosa belonging to Kalanchoe. The epidermal cells were polygonal or isodiametric ones in the leaves, and mostly rectangular, tetragonal, and elongated ones in the other organs. The candelabrum-like, triradiate stellete trichomes in the aerial parts of all organs of K. tomentosa were found. The cuticular striations and square crystals of calcium oxalate in the epidermal cells of petals of K. blossfeldiana were observed. The great majority of the mature stomata in various parts of all the organs were commonly helicocytic types. This type was subdivided into three subtypes such as parahelicocytic, anomohelicocytic, and dianisocytic stomata on the basis of the division angle of the guard mother cells. Sometimes, the anisocytic type was found in most organs. This type was subdivided into three subtyes such as paranisocytic, anomoanisocytic, and dianisocytic stomata in the same way as the helicocytic type. A new stomataltype with anisocytic stoma within a girdle of four subsidiary cells of tetracytic type in the leaf of K. kewensis was firstly observed in the vascular plants. This type was termed the coaniso-tetracytic type. The anomomeristic pattern in the mesogenous category of stomatal types was found in various organs of all the material plants. Developmental mode of stomata was constant in all the parts of each organ within the same plant. The stomata was observed to be a few similar stomatal types in various parts of each organ within the same plant. The ontogeny of all the types is eumesogenous or mesogenous type. The ontogenetic type of stomata was mostly helico-eumesogenous type in all the organs of all the material plants. The mature stomata varied from organ to organ in regard of the number and arrangement of subsidiary cells.

김정석,정우규,안중극,정미정,한창숙 ( Chung Suk Kim,Woo Kyu Chung,Joong Kug Ahn,Mee Jeong Jeong,Chang Sook Han ) 한국산림과학회 1986 한국산림과학회지 Vol.73 No.1

Karyotypes are described for Juniperus rigida Sieb. et Zucc. in two provenances of Gyeong-nam and Choong-puk. Chromosome numbers of two provenances, are 2n=22. The most common feature of mitotic chromosomes was shown at the chromosome 7, which has secondary constriction on the short arm. And the most differential chromosome was shown at chromosome 9 from Gyeong-nam and chromosome 5 from Choong-puk provenance, which bore secondary constriction. The karyotype formulae are as follows; Gyeong-nam, Jinyang pravenance race is K(2n) = 22 = 2 A^m + 2B^m + 2C^m + 2D^(sm) + 2E^(st) + 2F^m + 2^(sc)G^m + 2H^m + 2^(sc)I^t + 2J^(st) + 2K^m Choong-puk, Jechun provenance race is K(2n) = 22 = 2A^(rn) + 2B^m + 2C^m + 2D^(st) + 2^(sc)E^(sm) + 2F^m + 2^(sc)G^m + 2H^m + 2I^m + 2J^(st) + 2K^(sm)

김정석,김영두,정우규 ( Chung Suk Kim,Yeung Du Kim,Woo Kyu Chung ) 한국산림과학회 1985 한국산림과학회지 Vol.71 No.1

Cytological observations in the seven varieties of Juniperus chinensis L. showed three varieties (J. chinensis var. procumbens, J. chinensis var. kaizuka and J. chinensi.s var. aureo-variegata) were tetraploid with chromosome number, 2n=44, and rest of four varieties (J. chinensis var. horizontalis, J. chinensis var. sargentii, J. chinensis var. gtobosa and J. chinensis var. aureo-globosa) to be diploid, 2n=22. Chromosome configuration and behavior in the meiosis of P.M.C. of three tetraploids appeared to be slightly irregular. These results suggest that triploid tree can be artificially produced with these specific clones.

In this study the relationship among Juniperus chinensis and its seven varieties-J. chinensis var. procumbens, J. chinensis var. horizontalis, J. chinensis var sargentii, J. chinensis var, kaizuka, J. chinensis var. aureo-variegata, J. chinensis var. globosa, J. chinensis var. aureo-globosa-and J. rigida was studied by using the karyological methods. The results obtained from this study were as follows : In the karyotype analysis, J. chinensis, J. chinensis var. horizontalis, J. chinensis var. sargentii, J. chinensis var. globosa, J. chinensis var. aureo-globosa, and J. rigida were diploid with 2n=22, although J. chinensis var. procumbens, J. chinensis var. kaizuka and J. chinensis var. aureo-variegata were tetraploid with 2n=44. According to descending order of the total length of the chromosomes and the length of short and long arms, from the arrangement order of chromosomes and the position of centromeres, J. chinensis var. procumbens and J. chinensis var. horizontalis were categorized into the first group J. chinensis var. kaizuka and J. chinensis var. aureo-variegata were into the second group, and J. chinensis var, globosa and J. chinensis var. aureo-globosa were into the third group, respectively. Aneuploid(2n=26) in the C-band staining of J. chinensis var. aureo-variegata was identified, although it normally showed 2n=44 as karyotype. Because light was emitted from all chromatids of the samples by fluorescent light staining with DAPI, A-T rich regions would be located all over the chromatids.

김정석,정우규 慶尙大學校 1989 論文集 Vol.28 No.2

This study was carried out to investigate the epidermal structure and stomatal types on the upper and lower surfaces of leaves and stems in P. oleracea, P. glandiflora, and P. afra belonging to Portulaca. The shape of epidermal cells was tetragonal in the leaves of P. afra and polyponal in the leaves of P. oleracea and P. glandflora. The cell walls were straight in the leaves of P. afra, sinuous in the leaves of P. oleracea, and P. glandiflora. The size of the cells in the leaves of P. afra was smaller than that of the cells in the leaves of P. oleracea and P. glandiflora.Epidermal cells of stems were commonly small and tetragonal. The subsidiary cell walls were arched in P. afra and sinuous in P. olerdcea and P. glandiflora. The nature of sinuosity was more pronounced in the leaves of P. glandiflora. The number of stomata in the leaves of all materials was smaller than common thin-leaved dicots and higher on the upper surface in the leaves of all species. The stomatal types were paracytic in the leaves of P. afra and allelocytic in the leaves of P. oleracea and P. glandiflora. The compound allelocytic type was observed in the leaves of P. oleracea. The coallelo-anisocytic, coallelo-tetracytic and copara-helicocytic type in P. oleracea were found for the first in the vascular plants. The ontogenetic types of stomata were mesogenous of eumesogenous.

Kalanchoe속에 속하는 3種을 대상으로 잎과 꽃잎의 表皮構造와 氣孔의 發生類型을 조사한 結果는 다음과 같다. 잎의 表皮細胞는 主로 多角形이고 꽃잎의 표피세포는 主로 伸長形이었다. 이들의 細胞壁은 肥厚되었고, 直線形이거나 弓形이었다. 副細胞壁은 얇고 弓形이었다. K. tomenlosa의 잎에서 三方射星狀毛가 K. blossfediana의 꽃잎에서 角皮條紋과 옥살산컬슘의 結晶體가 발견되었다. 잎에서 氣孔의 數는 얇은 잎으로 된 일반식물에서 보다 적었고 잎의 양면에서 氣孔數의 차이도 일반식물에 비해 적었다. 성숙한 기공의 主類型은 螺旋型이었다. 기공의 發生學的 類型은 全中位形成 螺旋型이었고, 이 유형은 孔邊母細胞의 分裂角에 따라 全中位形成平行螺旋形과 全中位形成不規則螺旋形의 두 종류의 亞型으로 나눌 수 있었다. 全中位形成四副細胞型內不均等型 및 全中位形成對生型과 全中位形成不均等型의 中間型 기공의 부세포들 중앙에 全中位形成四副細胞型이 管束植物에서는 최초로 발견되었다. The epidermal structure and ontogeny of stomata in the leaves and petals Kalanchoe were described. The epidermal cells were mainly polygonal cells. These cell walls were thick and straight or arched. The subsidiary cell walls were thin and arched. The triradiate stellete hairs in the leaves of K. tomentosa, and the cuticular striation and square crystals of calcium oxalate in the petals of K. blossfeldiana were observed. The stomatal number in the leaves had relatively fewer stomata than thin-leaved common dicots with only one lower surface. The difference of stomata number on te both surfaces of leaves in each species was relatively lower than that of common plants. the main type of mature stomata was helicocytic type. the ontogenetic type of stomata was mainly helico-eumesogenous type. This type was subdivided into parahelico-eumesogenous and anomohelico-eumesogenous stomata on the base of the division angle of the guard mother cells. The coaniso-tetra-eumesogenous type and tetra-eumesogenous type in the center of the intermediate stoma between the allelo-eumesogenous and aniso-eumesogenous stomata in the leaf of K. kewensis were first observed in vascular plants.
