Effects of mycorrhizal infection on the growth of bell pepper (Capsicum annuum) and corn (Zea mays) seedlings have been studied by comparing plants grown in sterilized soil/sand mixtures to plants grown in sterilized soil/sand mixtures with topping the original non-sterile field soil. The original nonsterile field soil, which were taken from the bell pepper field, contained a high level of endmycorrhizal spores. After seven weeks, the shoot height of inoculated plants was increased by 110% in bell pepper, and 90% in corn compared with the control plants. The average above-ground biomass of inoculated plant was increased by 88% in bell pepper and 71% in corn compared with the control plants. The shoot-root ratios in bell pepper and corn were 2.7 and 1.8 for the control plants, and 4.3 and 2.7 for the treatment plants, respectively. Phosphorus level in inoculated plant was higher than that of the control plant. However, nitrogen contents were similar between the control and the treatment plants. The control plants didi not form vesicular-arbuscular mycorrhizae during the experimental period.

Response of two ploidy levels to cool temperature and short day treatment were investigated under controlled conditione of Phytotron. The haploid and diploid of seven genotypes were started and grown to the 8- leaf stage in the greenhouse. They were treated during 15 and 20 days to 8- hour photoperiods at 18$^{\circ}C$ in controlled - environmental room to induce premature flowering, respectively. Diploid plants of seven genotypes flower later than their haploid plants at 20 days treatment. But under 15 days treatment, diploid plants of NC82, Hicks, BY4, NC2326 and Coker86 were not different from their haploid plants for days to flower. Diploid plants of seven genotypes developed the same number of leaves as their haploid plants at 20 days treatment. Under 15 days treatment, diploid plants of Coker347 and NC95 developed more leaves per plant than their haploid plants. Correlation coefficient between the ranks of leaves per plant of seven genotypes at two ploidy levels was 0.964 and 0.929 at 15 and 20 days treatment, respectively.

Objective : For the purpose of making use the wild edible plants of Ulleung island smoothly, this study was designed. Method : For the first time, I searched the wild edible plants of Ulleung island from various data. And I examined herbological books and research papers on the wild edible plants of Ulleung island. Result : The herbaceous plants in Ulleung island were 12 family and 22 species, Compositae and Liliaceae plants take the highest number of them. The woody plants in Ulleung island were 1 family(Araliaceae) and 2 species. The herbal medicines that originated from the wild edible greens of Ulleung island were 25 species. The herbal medicines that have the effects of clearing away heat(淸熱), eliminating toxin(解毒), subduing swelling(消腫) and promoting blood circulation to remove blood stasis(活血祛瘀) take the highest number of the effects of these herbal medicines. Conclusion : For the purpose of making use the wild edible plants of Ulleung island smoothly, we should recognize not only medical benefits but also matters that pay special attention.

In order to understand the biological role of calmodulin in plants, transgenic tobacco plants expressing a calmodulin mutant (VU-4 calmodulin, lys to ile-115) gene have been analyzed. SDS-PAGE and Western-blot analyses showed that the foreign calmodulin mutant is stably and highly expressed in the transgenic tobacco plants. The levels of $H_2O_2$were elevated approximately 2-fold in the transgenic plants. Furthermore, the transgenic tobacco plants have more than 6-fold higher levels of NADPH compared to control tobacco plants. The present findings, combined with previous data showing differences in the susceptibility of the transgenic tobacco seeds and normal tobacco seeds to fungal contamination (Oh and Yang, 1996), suggest that the expression of the calmodulin derivative gene in tobacco plants could increase resistance to infection by fungal pathogens.

Geographical distribution of diploid plant with AA genome (2n=16) and allotetraploid with AABB genome (2n=34) of Scilla scilloides Complex from Korea has been studied. The composition and frequencies of B chromosomes ere also investigated. Plants with AABB genome were predominant over AA genome plants. A mixed population of AA and AABB genome plants was found for the first time. Aneuploid plants have not been found. Chromosomes of AA genome were composed of three pairs of metacentric, two pairs of submetacentric, two pairs of subtlocentric and one pair of telocentric chromosomes, whereas BB genome was four pairs of metacentric and five pairs of subtelocentric chromosomes. B chromosomes were classified into two categories, isochromosome (F) and chromosome fragment (f). The frequencies of B chromosomes were 43% in AA genome plants and 44% in AABB genome plants. The number of B chromosome ranged from 1 to 3 and 1 to 7 in AA and AABB genome plants, respectively. B chromosome combinations were F and F+f in AA genome plants and F, F+f and f in AABB genome plants.

This study was to estimate and complete the flora of herbaceous plants found in Mt. Kyeryong National Park, Mt. Bomoon, and Mt. Shikjang in Taejon Korea. This research was conducted from April 1995 to August 1998. Herbaceous vascular plants were composed of 76 families,336 genera,574 species,4 subspecies, 105 varieties and 9 forms, totaling 691 taxa. The useful resource plants were categorized as edible plants (45.4%), medical plants (31.1%), pasture plants (28.7%), ornamental plants (16.4%) and industrial plants (1.6%).

Because of very little information available regarding the poisonous plants distributed in Jeju-Island, the author made a survey of such plants from March, 1974 to Dec., 1977. The results obtained were as follows: 1. If not all, 68 families, 137 genera and 190 species of poisonous plants distributed in Jeju-island were classified. And 190 species were divided into 137 spp. of herbs, 45 spp. of shrubs, 3 spp. of molds and 5 spp. of toadstools. 2. Relatively, a large number of poisonous plants were distributed in wild field. Jungle area, inhabited region, seashore and high mountainous area took next place gradually by the number of plants. 3. And according to their toxic chemical components or poisoning types, they were classified as 16 spp. of cyanogenetic plants, 14 spp. of oxalate-producing plants, 14 spp. of nitrate. producing plants, 10 spp. of photosensitization and 136 spp. of the other activities.

The presence of saponin, terpenoid, steroid, anthraquinone and flavonoid were screened with the usual test methods in forty five(sixty four parts) Korean plants belonging to Urticaceae, Celastraceae, Rhamnaceae, Sterculiceae and Rubiaceae. Plants were extracted with methanol and fractionated with hexane, chloroform, ethyl acetate and butanol. Each fraction was tested for the components. The result showed that in saponin test, 21 plants were positive and 11 plants were weak positive; in terpenoid and steroid test, 26 plants were strong positive; in anthraquinone test, 20 plants strong positive; in flavonoid test, 31 plants were positive and 9 plants were weak positive.

This study intens to provide available guideline of useful plants in interior and be used by designer. It focuses on evaluating the character of plants, the method of installation and the form of composition for suitable design of using plants. The study finds out that using plants in interior are necessary positively by 94% respondents. And results of factor analysis are that plants are needed for emothional stability(factor 1), visual charming(factor 2), and educational effection(factor 3). According to job, the group of students is visual charming (P=0.0037), the public servants and housewives is educational effection(p=0.0029). The most available space of plants as follows : Department(30.5%), Hotell(26.3%), House and Restuarant(12.7%). It has been identified that the public institution and commercial space are much indused plants. The most indused plants in house is ordered that the veranda, the living room, the entrance. This result is concerned about relation of natural light plants. The repondants reply that the favorite arrangement style is the corner form(63%), the center garden form(52.1%), the large planter(19.7%), the planter box(11.3%). They respond that they are more favorite light green color than dark, and mono color than mixture color. Finally, interior Designers should be understood the functional and aesthetic elements and the special interest about plants for developing desigv.
