| Abstract: This study tested for effects of site preparation herbicides applied at high labeled rates 11 years earlier on plant species richness, diversity, and stand structure and composition. Four study sites in three physiographic provinces were established in central Georgia in 1984. Six herbicide treatments were included on each site: hexazinone liquid, hexazinone pellets, glyphosate, triclopyr, picloram, and a mixture of dicamba and 2,4-dichlorophenoxyacetic acid (2,4-D). Herbicide and untreated plots were prescribed-burned and planted to loblolly pine (Pinus taeda L.). Eleven years after treatment, 177 total species were identified in these dense pine plantations; 99 species were forbs and grasses-grasslikes. Treated and check plots did not differ in species richness or diversity. Structurally, the total basal area of the tree canopy was not significantly altered, but the proportion of pine to hardwoods and shrub stem density were influenced by treatment. Latent effects were detected in the abundance and frequency of Pinus taeda, Prunus serotina Ehrh., Quercus stellata Wangenh., Diospyros virginiana L., Vaccinium stamineum L., Vitis rotundifolia Michx., and Lespedeza bicolor Turcz. Most are potential mast producers for wildlife. Herbicide site preparation had little influence on total species numbers or their diversity 11 years after treatment but affected composition by altering perennial species abundance. |

| Abstract: This study was conducted to determine the effect of chemical properties of soil on the weeds development and plant coverage in pasture, 1988-1990. The total places of investigation in this survey were 567 pastures, and those were covered with all over the country, especially regions of Alpine, Northern, Middle-southern and Namwon except Cheju. The results obtained are summarized as follows: The coverages of Artemisia princeps, Ixeris dentata, Capsella bursa-pastoris and Lespedeza bicolor were increased with increment of soil pH, while those of Potentilla fragarioides and Rumex acetosella were increased with decrement of soil pH. The coverages of Capsella bursa-pastoris and Quercus dentata were increased as the organic matter of soil was increased, while those of Artemisia princeps, Rumex acetosella, Erigeron canadensis, Carex spp. and Polygonum persicaria were decreased. As the content of available phosphate increased, the coverages of Erigeron canadensis, Carex spp. and Pteridium aquilinum were increased, while those of Miscanthus sinensis, Quercus dentata and Quercus serrata were decreased. As the content of exchangeable cations(Ca2+, Mg2+, K+) increased, the coverages of Artemisia princeps, Capsella bursa-pastoris and Cocculus trilobus were increased, while those of Potentilla fragarioides, Rumex acetosella and Erigeron canadensis tended to decrease. |

| Abstract: Modes of recruitment of each regenerated species after fire were investigated quantitatively in a Pinus densiflora forest in central Japan. There was a continuum of regeneration modes from species with abundant seedling populations (more than one individual m super(-2)) to sprouters. The former included Erigeron canadensis, Eupatorium chinense var. simplicifolium, Rubus crataegifolius, Lespedeza bicolor forma acutifolia, Mallotus japonicus, Rhus javanica, Eurya japonica, Aralia elata and Weigela decora, whose seedlings accounted for 70% of total recruitment on the forest floor. Sprouts from stem bases which comprised much of the canopy prior to fire (e.g. Quercus serrata, Castanea crenata, Fraxinus sieboldiana and Prunus spp.), were vigorous and grew rapidly. Plants on both ends of the continuum dominated post-fire vegetation in the study sites. |

| Abstract: To investigate the procedure of natural plant succession on cutting slope in the forest roads, considered elapsed years and regional distribution, data were collected from natural and artificial treatment slope. And to elucidate the effective methods of revegetation on forest road slope, each seeding experiments carried out with 4 species (Themeda triandra, Lysimachia clethroides, Artemisia princeps and Lespedeza cyrtobotrya). The pioneer species on cutting slope in the forest road were Pinus densiflora, Lespedeza bicolor, Rhubus crataegiflora etc. in wood species, and Arundinella spp., Lysimachia barystachys, Artemisia spp. etc. in herb species. In process of year, plant coverage was increased and average of plant coverage was 30% in road slope which elapsed 5 years after construction. On short slope less than 3m, broadcast seeding method with straw mulch was more effective way than the other methods. Slope revegetation work should be adapted with forest road construction work and revegetation work with native species will be effective. |

| Abstract: The nitrogen fixation activity and environmental factors of Lespedeza bicolor Turcz, forming annual root nodules by symbiotic Rhizobium sp. were analyzed in the field conditions during the growing period. Seasonal changes of N-2-fixation activity showed the maximum value of 120 mu-M C-2H-4 cntdot nodule g fw-1 cntdot hr-1 during the active growing period (June) and varied significantly depending on the growth phase and environmental factors. The maximum activities were attained at the conditions of pH 7, 30 degree C of temperature, 18 Kpa of oxygen partial pressure and inhibited by water stress and nitrogen sources. The habitat soil was weak acidic and poor in nitrogen, phosphorus and organic matter contents. The leaf area ratios and chlorophyll contents were ranged from 442 to 483 cm-2 cntdot g dw-1 and from 33 to 38 mu-g chl cntdot cm-2. Nitrogen contents in each organ showed the maximum of 46, 19 and 11 mg cntdot g dw-1, respectively for leaf, root and stem in the early period. The highest phosphorus contents were 4.2, 1.2 and 0.6 mg cntdot g dw-1, respectively for leaf, root and stem in early growing period. The allocation ratios of nitrogen quantity showed 60% for leaves and 73% for roots during the active and late growth period, and 22% for stems in average. The allocation rates of phosphorus quantity showed 58% for leaves during the most productive period, 70% for roots in the pre-growth stage and 26% for stems in average. |
