Taxonomical studies of the genus Acer in Korea (8 species, 3 varieties and 1 forma) were studied by the morphological characteristics of stipules. The results obtained were summarized as follows; 1) The stipules of the genus Acer were arranged oppositely with 4 - 10 stipules consisting of simple leaf, compound leaf and unifoliate compound leaf. The venation of stipules were cladodromous, basal reticulate, fibrous and palmately netted vein. The trichoma of stipules were glandula hair, glandular pubescent, sericeous, pilous, vinous, velutinous, tomentose, ciliate and lanate. As the morphological characteristics of stipules in the genus Acer established a strong point in the identification of species. 2) The species in the genus Acer in Korea were classified into six groups; (1) ginnala group (A. ginnala), (2) koreanum group (A. koreanum, A. japonicum, A. pseudosieboldianum var. koreanum), (3) mono group (A. mono, A, palmatum var. sanguineum, A. palamtum var. dissectum, A. palmatum var. dissectum f. aosidare), (4) negundo group (A. negundo), (5) palmatum group (A. palmatum), (6) platanoides group (A. platanoides, A. truncatum) by the morphological characteristics of stipules, 3) The stipules of platanoides group and negundo group were the least evolved types among the species in the genus Acer. 4) The stipules in the genus Acer were made the inner buds that were metamorphosed to the protected functional aspect by the evolution of petiols.

Rubus palmatus Thunb. var. palmatus (Rosaceae) was first discovered in Anmyeon-do and Geoje-do, Korea, and the new Korean name 'Gin-yip-dan-pung-ttal-gi' was given. This taxon can be distinguished from var. coptophyllus by having 3-lobed or rarely undivided leaves. We, for the first time, report the distribution of R. palmatus var. coptophyllus (A. Gray) Kuntze from the island of Geoje-do in Korea and clarified the Korean vernacular name of 'Dan-pung-ttal-gi.' Finally, we designated the lectotype of R. palmatus using C. P. Thunberg's specimen (UPS-THUNB. 12282).

In order to observe the anatomical phenomena of root formation in the hypocotyl cuttings of maples, the hypocotyls of Acer palmatum. Acer micro-sieboldianum, and Acer saccharinum were used as the materials. The rooted portions were sectioned by a microtom and doubly stained by safranin and fast green. The results obtained are summarized as follows; 1. A cross section structure of hypocotyl cuttings of Acer sp. is consist of epidermis, cortex, vascular bundle and pith from the outside. The vascular bundle makes circular shape forming polyarch in A. saccharinum and tetrarch in both A. palmatum and A. micro-sieboldianum. 2. An adventitious root of A. saccharinum originated in phloem parenchyma, while that of A. palmatum and A. micro-sieboldianum originated in interfascicular parenchyma related with phloem cells. 3. The hypocotyl cuttings of Acer sp. is commonly composed of parenchyma tissue having vigorous differentiation capability. Therefore, the originated root grow easily through the cortex and epidermis breaking their tissues.

This study was carried out to develop new cultivars of Z. serrata showing yellow fall leaf. Z. serrata which had yellow fall leaves were selected and then examined for contents of leaf anthocyanin and chlorophyll. In addition, for the progeny test, selected trees were grafted. Of 21 trees having yellow autumn leaves, three individuals, 'S-4', 'S-14', and 'J-32' were finally selected. They contained high level of anthocyanin with higher level in the leaves. Once developed, the yellow color remained till late autumn. Grafted plants of the selected strains showed high grafting efficiency and vigorous growth. Yellow foliage color were found to be maintained in the grafted trees. The tree 'S-4' was 7 m tall and 6 m in crown width, whereas 'S-14' and 'J-32' were 6 m tall and 4m in crown width. The soil pH of the survey sites ranged from 5.9 to 7.24. However, other soil characteristics did not show much difference among the sites with regard to inorganic nutrients including $N,\;P_2O_5,\,CEC,\,K^+,\,Ca^{2+}$, and $Mg.^{2+}$ 'S-4', 'S-14', and 'J-32' clonal lines developing yellow fall leaf were selected as new cultivars and propagated by grafting.

The pollen morphology of 19 species and 1 variety of the genus Acer L. in Korea was investigated by light and scanning electron microscopy. The results are as follows ; 1. A. pollen key of the genus Acer L. in Korea was provided in four types. 2. Based on the aperture types and sculpture patterns, the four major pollen types of the genus Acer L. in Korea were recognized which included palmatum, barbinerve, negundo and saccharum types. 3. Pollen grains are tricolpate or tricolporate on the aperture, and striate, rugulate or reticulate on the sculpture pattern. 4. As the result of the correlation analysis between the five measured pollen parameters in pairs, a highly significant positive correlation was found between polar axis length(PL) and colpus length (CL).

The leaf persisting and seasonal leaf color characteristics of deciduous woody landscape plants were investigated through the field survey in Suwon region. The leaf period was about 270 days from March 20, 1992 when Prunus padus was leaf spreading to December 17, 1992 when Lonicera sempervirens was leaf falling. The plants of leaf period over 240 days were Elaegagnus umbellata var. coreana, Salix pseudo-lasiogyn, Ligustrum obtusi-folium, Rosa multiflora, Lonicera sempervirens and Clematis viticella. The woody landscape plants bearing the red leaf by KBS standard color number before fall foliage coloring were Prunus salicina, Berberis thunbergii 'Atropurpurea', Acer platanoides 'Red King', Acer palmatum var. Pendula 'Crimson Queen', Parthenocissus tricuspidata, Nyssa sylvatica, Acer palmatum var. sanguineum, and the yellow leaf, Berberis thunbergii Variegata 'Aurea', Physocarpus opulifolius 'Luteus', and Forsythia koreana 'Seoul Cold', Ligustrum X vicaryi which is variegation. The fall foliage color period was about 100 days from September 6, 1992 when Euonymus alatus was fall foliage coloring, to December 17, 1992 when Lonicera sempervirens was leaf falling. (Table 24) And in terms of color based on KBS standard color number, 60.7% of fall foliage were yellow, 37.4%, red, respectively.

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.

산채는 사람에 의하여 개량 육성되어 논밭에서 재배하고 있는 농작물과 달리 자연 그대로 산야에서 자생하는 식물 중 식용으로 가능한 것을 말한다. 우리나라 산야에는 480종의 식물이 식용으로 이용될 수 있다고 하나 현재 전국에서 재배하고 있는 작목은 36종으로 추정되며, 앞으로도 80여 종이 개배 가능한 작물로 추정된다. 산채류의 이용형태별 생산가능시기는 3~5월의 생채 생산과 6~7월의 건채 생산으로 소비자의 기호에 부합하는 신선 생채의 소비한계는 제한되어 있기 때문에 재배유형별 생채 수량검정을 통해 수확시기 연장 및 재배품목을 다양화 시킬 필요 있다. 이에 본 시험은 산채류 재배유형별 수확기간을 구명하고자 표고 500 m의 전북 남원시 허브산채시험장에서 2018년 5월 말 갯기름나물 등 15 종을 노지와 하우스에 정식하여 각 작물의 생육특성, 수확한계기 등을 조사하였다. 1년차 지상부 생육특성을 조사한 결과 참취, 개미취, 섬쑥부쟁이, 질경이, 갯기름나물, 두메부추, 돌단풍, 참당귀의 경우 초장, 엽장 등은 노지보다 하우스에서 높은 편이었고 생존율은 비슷하거나 하우스에서 더 높은 경향을 보였다. 우산나물, 단풍취의 생존율은 하우스에서 더 높았으나 생육 초기 엽소현상으로 인해 1년차 생육은 노지, 하우스에서 둘 다 저조하였고 곤달비, 어수리, 곰취, 눈개승마의 경우 노지에서는 7월 중순이후 지상부가 전부 고사하였으나 하우스에서는 생존율이 상대적으로 양호하여 11월 상순까지 후기 생육을 하였다. 2년차 산채류 출현기 조사한 결과 하우스 재배에서 산마늘이 2월 중순으로 가장 빨랐고 갯기름나물, 곤달비 등 10종이 2월 하순에 출현하였으며 참당귀 3월 상순, 단풍취 및 우산나물 3월 중순, 돌단풍이 가장 늦은 3월 하순에 출연하였다. 생체수확 시기는 갯기름나물, 눈개승마, 산마늘, 두메부추, 섬쑥부쟁이는 3월 중순부터 가능했고 곤달비 등 12개종은 3월 하순, 우산나물은 4월 상순, 돌단풍은 4월 중순으로 가장 늦게 생체수확이 가능했다. 노지 재배의 경우 산마늘과 눈개승마가 3월 중순으로 가장 빨랐고 갯기름나물 등 10종이 3월 하순에 출현하였으며 돌단풍, 참당귀, 단풍취가 4월 상순으로 가장 늦은 출연을 보였다. 생체수확 시기는 눈개승마와 산마늘이 4월 상순으로 가장 빨랐으며 갯기름나물 등 10종이 4월 중순부터 가능했고 돌단풍, 참당귀, 단풍취가 4월 하순으로 가장 늦었다. 수확한계기 조사 결과 눈개승마, 산마늘, 우산나물은 하우스 및 노지재배에서 20일정도로 가장 짧았으며 그 외 작물들은 계속적으로 수확이 가능하였으나 6월 상순 이후에는 품질이 나빠져 생체상품으로서 가치가 없었다.
