Maesopsis eminii, known as ‘umbrella tree’ in English, occurs naturally between 6oS and 8oN in tropical Africa. It is a species of moist forests and an early succession species, adapt at colonizing grasslands and disturbed areas in the high forest. It is widely distributed in forest re-growth and remarkably long lived for a pioneer species, attaining over 150 years. M. eminii was introduced into Java, Indonesia in the 1920s and has been widely cultivated in Java, Sumatra and Kalimantan for timber plantations due to its timber value, fast growing and leave usage for fodder. Annual wood production potential is 30 m3/ha in Africa and 40 m3/ha in Indonesia. The final rotations for timber production are 20-30 years in Africa and 10-20 years in Indonesia, and rotations for fuel wood, poles and pulp production are about 8 years. Genetic resources (plus trees) of M. eminii growing in several populations from west Java were collected, and a progeny test of the 100 open-pollinated families was established in west Java, Indonesia. Early results from a field test of M. eminii are reported from the progeny test trial. Seedling height and diameter at root collar (DRC) were measured at 0, 10 and 15 months of ages. Age 0 means the measurement just before the planting. The averages of seedling height and DRC at age 15 months were 134.4 cm and 1.86 cm. Family survival rates were, on average, 65.6% and 62.8% at age 10 and 15 months, respectively. Family genetic variance and replication variance at age 15 months were higher than those at age 10 months. Seedling height was positively correlated with DRC growth and statistically significant at the same ages. The coefficients of genetic variation for seedling height and DRC were ranged from 0.01 to 12.69 and from 1.97 to 13.70. Heritability estimates obtained were 0.44, 0.04, 0.01, and 0.31, 0.01 and 0.02 for seedling height and DRC at age 0, 10 and 15 months, respectively. Family averages of the 10 best and the 10 poorest families for each trait indicated that there were large differences of seedling height and DRC growth among families and between ages. Genetic gain for DRC was expected to be substantial and higher than that for seedling height growth at age 15 months. Those results suggested that growth improvement through the superior family selection of M. eminii could be possible.

N/A Background : The function of the p53 protein is known to regulate cell proliferation by inhibiting cells entering S phase, so DNA damaged cell proliferation is inhibited by apoptosis. p21 is a cyclin dependent kinase inhibitor induced by wild type p53, not mutant p53. Thus p21 is thought to mediate the signal of p53 induced by DNA damaged agents to arrest the cell cycle in G1 phase. p53 and p21 are expressed in many malignant tumors, and its role in oncogenesis, tumor progression and prognosis are important. Objective : The purpose of this study was to analyze immunogistochemical expression of mutant p53 and p21 protein in melanocytic lesions. Method : 11 cases of intradermal nevus, 7 cases of junctional nevus and 6 cases of malignant melanoma were immunohistochemically stained with p53 and p21 monoclonal antibodies. Results : 1. In intradermal nevus, the p53 was negative in 100% and the p21 was negative in 98%. These findings suggest that the composing cells of intradermal nevus is completely mature cell. 2. The positive rates of p53 and p21 in junctional nevus were 43% and 43%, respectively. The positive rates of p53 and p21 in malignant melanoma were 82% and 67%, respectively. Conclusion : If the expression of p21 is induced by p53 independent pathway, the cell cycle can be arrested in G1 phase, so the tumor cell proliferation is inhibited. But if the expressed p21 is mutated as p53, it means that the natural function of p21 disappears. More research is necessary about the nature of p21 which is expressed with mutant p53.

본 연구는 울릉도 고추냉이 개체군의 식생과 토양특성, 분포서열법을 분석하기 위해 수행되었다. 고추냉이 개체군은 서면의 해발고 440m에서 570m 사이와 나리분지의 해발 340m 부근에 분포하고 있다. 고추냉이 군락지의 토양은 유기물함량 15.01%, 전질소함량 0.48%, 유효인산함량 44.19mg/kg, 치환성 K 2.00(me/100g), 치환성 Ca 7.19(me/100g), 치환성 Mg 4.44(me/100g), 양이온치환용량 22.55(me/100g)로 높게 나타났으며, 토양 pH는 6.17로 약산성 토양의 특징을 나타내고 있다. 일색고사리 우점개체군은 좀깨잎나무 우점개체군보다 전질소, 유기물함량, CEC, 치환성 Ca 등이 다소 많은 입지에 분포하고 있는데 반하여 좀깨잎나무 우점개체군은 일색고사리 우점개체군보다 pH가 다소 높은 입지에 분포하고 있었다. This study was carried out to analyze the vegetation and soil characteristic, and ordination of Wasabia japonica population at Ulleung-Do. The Wasabia japonica population is distributed in altitudes of 440m to 570m at Seo-Myon and also in altitudes of 340m near Nari-valley. In the study sites, soil organic matter, nitrogen, available phosphorous, exchangeable potassium, exchangeable calcium, exchangeable magnesium concentration, cation exchange capacity, and soil pH were 15.01%, 0.48%, 44.19ppm, 2.00(me/100g), 7.19(me/100g), 4.44(me/100g), 22.55(me/100g), and 6.17, respectively. The Rumohra standishii dominant population was mainly found in high in soil nitrogen, organic matter, CEC, and exchangeable calcium concentration in comparison with Boehmeria spicata dominant population. The Boehmeria spicata dominant population was mainly found in high in soil pH.

Quantitative genetic parameters were estimated for three characters that are important to timber production and survival of Peronema canescens planted in West Java and Central Kalimantan, Indonesia. Significant clonal variation was detected for tree height, diameter at breast height (DBH) and survival rate among 150 clones of P. canescens by age of four years. Clonal survival rates were, on average, 47.8 % in West Java and 29.2 % in Central Kalimantan. The averages of tree height and DBH in Central Kalimantan were higher than those in West Java (4.71 m vs. 1.30 m in height and 8.73 cm vs. 1.72 cm in DBH). Tree height growth was significantly correlated with DBH growth whereas rank correlation of growth trait between sites was weak and non-significant. Highly significant differences in height, DBH growth and survival were observed among sites and between clones. The broad sense heritability was estimated separately in each site which was shown to be under moderate genetic control. Expected genetic response was estimated as a percentage of test mean in tree height and DBH growth after one generation of selection. The genetic response for tree height was expected to be 11.5 % in Java and 12.8 % in Kalimantan when the best 50% of superior clones were selected and used in a planting program. This result suggests that genetic improvement of growth traits through clone selection in P. canescens would be possible. The genetic gain could result in substantial returns if a large planting program would be developed.

This study was carried out to analyze vegetation and soil characteristic, and ordination of Scrophularia takesimensis population, Ulleung Island. The Scrophularia takesimensis population was classified into Aster spathulifolius for. oharai dominant population, Vitis amurensis dominant population and Scrophularia takesimensis typical population. The Scrophularia takesimensis population was located in elevation of 1m to 6m, in Ulleung Island. In the study sites, soil organic matter, nitrogen, available phosphorous, exchangeable potassium, exchangeable calcium, exchangeable magnesium and exchangeable sodium concentration, and cation exchange capacity, and soil pH were 9.1~19.1%, 0.19~0.52%, 87.1~196.7mg/kg, 2.0~2.8cmol+/kg, 5.4~5.9cmol+/kg, 5.9~8.8cmol+/kg, 4.4~4.8cmol+/kg, 20.3~ 26.7cmol+/kg, and 6.8~8.0, respectively. The Vitis amurensis dominant population was mainly found in the high percentage of total nitrogen, organic matter, CEC in comparison with Aster spathulifolius for. oharai dominant population.
