  • The effects of salt are studied on control of weeds and growth of Korean turfgrass(Zoysia japon-ica Steud.). And the mobility of salt were determined in a lawn field. At post-emergence stage, the growth of the 13 weeds such as Trifolium repens, Erigeron canadensis, Artemisia prieceps, Equi-setum arvense, etc were controlled by treatment of salt and salt water, Pea-annua and Equisetum arvense were tolerant to salt compared with the other 11 weeds. At pre-emergence stage, the salt controlled the germination of the weeds in soil. 300~500 kg /10a salt and 20~30 % salt waterwere enough for the control of weeds, However, salt water injuried the lawngrass except the dormancy stage. The mobility of salt in soil was increased by rainfall. After 160mm of rainfall, the salinity in the soil treated with salt 500kg /l0a was below 0.3 ms/cm in surface soil and about 0.1 ms /cm in soil 30 cm depth. Key words: Soil environmental survey, Korean turfgrass, Salt, Salt water.

  • Laboratory and greenhouse studies were conducted to evaluate effects of spray volumes and surfactants, L-77 and Triton CS-7 on leaf retention of glyphosate in Zea mays, Hordeum vulgare, Artemisia princeps, Trifolium repens and Equisetum arvense. Leaf retention was increased when glyphosate with L-77 or Triton CS-7 was applied in a spray volumes of 10-20 l/10a in Zea mays and 40 l/10a in Artemisia princeps but decreased when spray volumes were higher than above volumes and 40-80 l/10a in Trifolium repens. Hordeum vulgare leaves retained more spray when glyphosate with L-77 or Triton CS-7 was applied in all spray volumes tested. Equisetum arvense retained higher amount of spray by application of glyphosate with L-77 compared with Triton CS-7 and no surfactant treatments.

  • The anti-proliferating effects of some plants on hepatoma cell lines were studied by the 3-[4,5-dim-ethylthiazol-2yl]-2,5-diphenyl-tetrazolium bromide (MTT assay), to investigate the anticancer effect with some plants around here. As the result, we saw that the anti-prolferating effect to the plants. Among the plants, Equisetum arvense L. and Lactuca dentata Makino. var, flaviflora Makino of them relatively showed a good ant-proliferating effect. Capsicum annuum L. var. angulosum Mill (Leaf) was the best among them. We also examined morphological changes on the hepatoma cells in this process. In case of Capxicum annuum L. var. angulosum Mill, the tells become vague after 2 days, and then destroyed faster than others. We can fee also the condensated chromosome on the treated cells with Capxicum annuum L. var. angulosum Mill. And we also observed condensation through using a fluorescent microscope by PI staining, and observed DNA fragmentation.

  • This study was analyzed to photosynthetic pigment concentrations and changes of SOD activities on seven species of liana of A. heterophylla, P. scandens, V. thunbergii, P. tricuspidata, C. trilobus, L. japonica and T. kirilowii, and two species of E. arvense and A. princeps of non climbing plants. Concentrations of chlorophyll a and b, total chlorophylls and total carotenoids of P. tricuspidata in 100 ppb ozone site were the most increased. It was the most increased to P. scandens in ratio of chlorophylls and carotenoids, and E. arvense in ratio of chlorophyll a and b. There was difference to ratio of chlorophyll a and b of liana and non liana. At ratio of chlorophyll a and b of 100 ppb ozone site and the control it was more sensitive to chlorophyll a than chlorophyll b, and P. tricuspidata was the most sensitive at comparing with species, and it was more sensitive to liana than non liana. In SOD activities A. princeps was the most increased to 3535.7 unit/g, and P. scandens was the fewest increased to 109.3 unit/g, and A. heterophylla was only decreased to 131.7 unit/g in comparing to 100 ppb ozone sites and the control.

  • Crabgrass (Digitaria sanguinalis L.), Dandelion (Taraxacum platycarpum H. DAHLST.), Annual bluegrass (Poa annua L.), Gree kyllinga (Kyllinga brevifolia var.), Red clover (Trifolium pratense L.), Annual lespedeza (Kummerowia striata (Thunb.)Schindl.), Mugwort (Artemisia capillaris Thunb.), Horseweed (Erigeron canadensis L.), Field horsetail (Equisetum arvense L.) are major weeds in turf. In this study, 23 medicinal plant extracts were tested for herbicidal activities against crabgrass and dandelion in the course of major weed in turf. In pot experiment, we implemented pre-emergence application used medicinal plant extracts showed herbicidal activity in petridish experiment. In effect, inhibition rates of germination were 61.0% at Curcuma longa extract and 62.5% at Cnidium officinale extract in crabgrass pot experiment, and 77.8% at Ailanthus altissima extract in dandelion pot experiment.

  • Field and greenhouse trials were conducted to evaluate application variables including spray volume, surfactant, and simulated rain affecting phytotoxicity of glyphosate for enhancing efficacy of postemergence herbicides. Glyphosate phytotoxicity was increased by addition of surfactants, L-77 and Triton CS-7 to glyphosate solution in Artmesia princeps and Equisetum arvense and addition of Triton CS-7 to glyphosate solution enhanced control of Trifoliurn repens. Simulated rain within 4 or 8 hours after glyphosate application reduced glyphosate phytotoxicity. However, addition of L-77 and Triton CS-7 to glyphosate solution increased glyphosate phytotoxicity reduced by simulated rain in Artmesia princeps and Trifolium repens.

  • The aim of this study was to provide basic informations for restoring a habitat of Nannophy pygmaea Rambur. Environments and flora of the habitats were investigated in Youngdong, Sanbuk, and Nongam South Korea. The habitats were abandoned paddy fields with tree-unshaded space and with the water depths of about 2 - 10 cm all the year round. The water quality was recorded 5.44 - 7.33 in pH, 0.017 - 0.480 dS/m in EC, 1.34 - 4.94 mg/L in T-N and 0.06 - 0.46 mg/L in T-P. The pH and EC showed a wide range values, and T-N and T-P showed a high values comparatively. This result implies that a water quality does not important as the condition for a habitat of the species. A total of 86 vascular plant taxa belonging to 35 families, 60 genera, 67 species, 2 subspecies, 14 varieties and 3 forma were recognized in the habitats. Twenty two species (25.6%) overlapped among the habitats; Equisetum arvense, Salix koreensis, Persicaria thunbergii, Stellaria alsine var. undulata, Hypericum laxum, Kummerowia striata, Epilobium pyrricholophum, Oenanthe javanica, Mosla dianthera, Utricularia vulgaris var. japonica, Plantago asiatica, Eupatorium lindleyanum, Juncus diastrophanthus, J. effusus var. decipiens, J. papillosus, Aneilema keisak, Alopecurus aequalis, Arthraxon hispidus, Carex dickinsii, Cyperus sanguinolentus, Eleocharis acicularis for. longiseta and E. congesta. Biological type was determined to be HH-R5-D4-e(t) type; HH 39 taxa (45.3%), R5 42 taxa (48.8%), D4 59 taxa (68.6%) and e (or t) 23 taxa (26.7%).
