Use impacts on environmental deteriorations of trail and campsite were studied in Chirisan National Park in 1991. The entire width, bare width and maximum depth of trail as the trail condition were significantly greater on the more heavily used trail. Trail conditions, especially altitude, entire width and maximum depth of deteriorated points which were surveyed at the total of 82 were significantly different from those of non-deteriorated points. On the ridge trail, the damaged are more severe than Class 4 reaches about 34,000$m^2$ and use impacts on campsite and deterioration were also accelerated. The dominant trees of the upper layer in trail edge vegetation are changed from Carpinus tschonoskii to Quercus serrata, Carpinus laxiflora and to Quercus mongolica, Carpins laxiflora at Hwaeomsa trail, and from Quercus serrata to Quercus mongolica at Piagol trail. Also Lespedoza maximowiczii, Symplocos chinensis, Deutzia prunifolia, Weigela Subsessilis appear as the dominant lower species at Hwaeomsa trail, L. maximowiczii, S. chinensis, Stephanandra incisa, Rhododendron schlippenbachii for Piagol trail.

Inter simple sequence repeat (ISSR) markers were performed in order to analyse the phylogenetic relationships of four taxa of Castor-aralia (Kalopanax pictus): K. pictus, K. pictus var. magnificus, K. pictus var. maximowiczii, and thornless K. pictus. The 11 primers were produced 64 reproducible ISSR bands. Analysis of ISSR from individual plants of Korean K. pictus resulted in 41 polymorphic bands with 64.1%. When species were grouped by four taxa, within group diversity was 0.115 $(H_S)$, while among group diversity was 0.467 $(G_{ST})$ on a per locus basis. The estimated gene flow (Nm) for K. pictus var. maximowiczii and K. pictus var. magnificus were very higher than K. pictus. It is suggested that the isolation of geographical distance and reproductive isolation among K. pictus populations may have played roles in shaping the population structure of this species. In phenetic tree, ISSR markers are very effective in classifying natural populations as well as taxon levels of genus Kalopanax in Korea.

In this study, uptake and toxicity of disel (TPH) by poplar specie, $P.\;nigra{\times}P.\;maximowiczii$ were assessed in laboratory soil column experiments. Poplar cuttings were grown for 2 months and exposed to various concentration (0, 200, 500, 1000, 2000 mg/kg) of disel for a period of 60 days. For disel removal experiments, disel was effectively removed in the range of lower concentration. but, the removal rate of disel was rapidly decreased as increasing initial disel concentrations. For the this reason, toxicity effetcs were evaluated by measuring in poplar cutting mass variation and monitoring transpiration. Exposure on higher disel concentration resulted in decrease of biomass and transpiration accompanied by chlorosis and abscission, indicating toxic effect of disel on the poplar tree. And also, we have observed that both removal efficiency of disel and the microbial activity were higher at the bottom of the soil column. It was suggested that the plant formed the root zone at contaminated soil, stimulated microbial activity by plant root exudates, and played an important role in enhanced biodegradation of disel.

Molecular characterization of different genotypes reveals accurate information about the degree of genetic diversity that helps to develop a proper breeding program. In this study, a total of 30 EST-based simple sequence repeat (EST-SSR) markers derived from trumpet lily (Lilium longiflorum) were used across 11 native lily species for their genetic relationship. Among these 30 markers, 24 SSR markers that showed polymorphism were used for evaluation of diversity spectrum. The allelic number at per locus ranged from 1 at SSR2 locus to 34 alleles at SSR15 locus, with an average of 11.25 alleles across 24 loci observed. The polymorphic information content, PIC, values ranged from 0.0523 for SSR9 to 0.9919 for SSR2 in all 24 loci with an average of 0.3827. The allelic frequency at every locus ranged from 0.81% at SSR2 locus to 99.6% at SSR14 locus. The pairwise genetic dissimilarity coefficient revealed the highest genetic distance with a value of 81.7% was in between L. dauricum and L. amabile. A relatively closer genetic distance was found between L. lancifolium and L. dauricum, L. maximowiczii and L. concolor, L. maximowiczii and L. distichum (Jeju), L. tsingtauense and L. callosum, L. cernuum and L. distichum (Jeju ecotype), of which dissimilarity coefficient was 50.0%. The molecular fingerprinting based on microsatellite marker could serve boldly to recognize genetically distant accessions and to sort morphologically close as well as duplicate accessions.

In order to investigate the variation of nutritive value, fertilizer value, productivity and growth performance by the number of cutting times in Lespedeza bicolor, Lespedeza maximowiczii and Lespedeza japonica var. intermedia, the plots of one, two and four cutting times in a year had been made through 1972 to 1973. The results are summarized as follows. 1. Lespedeza bicolor, Lespedeza maximowiczii and Lespedeza japonicavar. var. intermedia showed increase of growth and productivity in two plots excluding the plots of four time cuttings. 2. Significant differences at 1% level were shown among the species and the number of cutting times in total grass yield. Lespedeza bicolor showed the greatest production, and followed by Lespedeza maximowiczii and Lespedeza japonica var. intermedia. The plots of one cutting time a year produced more dry weight than that of two and four cutting times. The production in plots of fourth cutting showed less growth and yield. 3. The ratios of dry weight to fresh weight and of leaf weight to stem weight were decreased when the number of cutting times increased in Lespedeza bicolor, Lespedeza maximowiczii and Lespedeza japonica var. intermedia. 4. Crude protein was decreased, though crude fiber content was increased when the grasses were growing more and more. Conent of crude fat showed great variation by the number of cutting times and cutting period seoson. 5. Early cut tings of Lespedeza showed higer fertizer value than late cuttings in all the species. 6. It is suggested that two and three time cutting through a year in Lespedeza bicolor and Lespedeza japonica var. intermedia having high nutritive and fertilizer value is good when using the Lespedeza species as a fodder or manuers, and one time cutting a year will be good when using the Lespedeza species as a fuel.
