Jeju Islands is a volcanic island located at the south sea of the Korean Peninsula. The forest soil of it had been originated from volcano eruption of Hallasan on which more than 1,800 plant species are growing including around 500 rare and endangered ones. There are also some valuable plants which have so specific traits that could be developed as new cultivar. We have searched these indigenous Plants in Jeju island like Chloranthus glaber, Cleyera japonica, Illicium anisatum, and Ilex rotunda. We have investigated the vegetation on the natural districts of these four species and selected multiple characteristics of growth form, leaves and fruits.
In addition to major 3 species(Chrolanthus glaber, Illicium anisatum, Cleyera japonica) 10 species of evergreen broad-leafed trees were selected, these species' habitats were confirmed and leaf characters were analyzed to secure genetic resources and grasp possibility of the development of the plant resources.
Chrolanthus glaber‘ habitats was confirmed in the Yeongju bridge and Don-naeko valley. Leaf character analysis showed that the leaf length was 12.4±2.2cm, leaf width 4.6±1.1cm, and the petiole length was 1.3±0.5cm. The Warm-temperate Forest Research populations showed the highest numerical value while Yeomiji Botanical Garden populations showed the lowest value.
Illicium anisatum' habitats was confirmed in 3 sites of the eastern part and 1 site of the southern part of Mt. Halla. Leaf character analysis showed that leangth of leaf was 7.5±1.1cm, leaf width 3.0±0.6cm, and the petiole length was 1.3±0.3cm. All populations showed similar to numerical value however Seogeomeun-oreum populations showed relatively higher value than any other population.
Cleyera japonica distributed mainly in southern slope of Mt. Halla. Leaf character analysis showed that the leaf length was9.0±1.2cm, leaf width 3.1±0.cm5, and the petiole length was 0.8±0.2cmcm. All populations showed similar to numerical value but of upper Don-naeko valley populations showed relatively higher value than any other population.
Leaf character of 10 species, exclusive of major 3 species showed that the leaf length of Camellia japonica was 103.18±10.94mm, leaf width was 42.56±4.84mm, the petiole length was 10.61±1.40mm, the leaf length of Eurya japonica was 60.09±5.77mm, leaf width was 24.03±2.01mm, the petiole length was 3.88±0.81mm, the leaf length of Eurya emarginata was 40.69±3.56mm, leaf width was 17.25±1.38mm, the petiole length was 2.68±1.64mm, the leaf length of Myrica rubra was 101.74±18.79mm, leaf width was 28.44±7.68mm, the petiole length was 7.52± 1.22mm, the leaf length of Neolistea aciculata was 94.21±13.07mm, leaf width was 28.02±3.48mm, the petiole length was 10.12±1.90mm, the leaf length of Ilex cornuta was 57.11±6.48mm, leaf width was 34.62±7.27mm, the petiole length was 7.00±2.02mm, the leaf length of Ilex integra was 81.00±5.16mm, leaf width was 28.97±2.69mm, the petiole length was 16.93±1.71mm, the leaf length og Ilex rotunda was 96.41±9.03mm, leaf width was 37.51±3.57mm, the petiole length was 25.47±2.54mm, the leaf length Lingstrum japoncum was 75.92±7.38mm, leaf width was 38.07±4.31mm, the petiole length was 9.41±1.59mm, and the leaf length of Pittosporum tobira was 80.59±8.68mm, leaf width was 30.08±3.43mm, the petiole length was 13.20±3.05mm. Leaf character variation within most species is showed equable distribution, however Myrica rubra showed extreme variation in the leaf length and leaf width.
Seed and scions were collected from the selected and propagated. The growing pattern and expression of scions were surveyed. To breed the unique cultivar, we have focused on each own characteristics. About some chracters, we are patent pending. Ilex rotunda. called Chinese holly tree is one of the woody plants grown at east China, Japan and Korea. Most Ilex observed are female plants because of their attractive fruit ripen from October to December as well as their multiple landscape value. However its habitat in Jeju island in Korea is restricted and due to illegal cutting, only few individuals are left. The phenotypic varieties of the tree could be use to produce a new cultivar. In Japan, Illicium anisatum, and Cleyera japonica, are being used in the censer stand as a symbol of forever due their evergreen leaves. Chloranthus glaber has so attactive red fruit ripen from October to next May that could be developed as a purifying indoor air plants.
To produce a indoor decorable cultivar, we have also examined three species (Chloranthus glaber, Ilex rotunda and Illicium anisatum) seedlings which have a different level of shade tolerance, grown under different light regimes on the full sunlight and 50% shading of the full sunlight. I. anisatum (shade tolerance species) had a significant difference between full sunlight and treatment. I. rotunda (intermediate species) showed high photosynthetic rate and WUE over PPFD 1000 μmol m^-2s^-1 on full sunlight. Besides, I. anisatum grown under full sunlight showed lower photosynthetic rate and WUE over a range of all PPFD. Chloranthus glaber seedlings were raised under four light conditions; PPFD 400, 250, 100 μmol m^-2s^-1 and full sunlight (PPFD 1600 μmol m^-2s^-1). In the full sunlight, Chloranthus glaber showed lower chlorophyll contents, photosynthetic rate and stomatal conductance than all of shading treatments except intercellular CO₂ concentration. The results from the study of shading treatment suggested that Chloranthus glaber adapted to low light intensity on growth and physiology. and I. rotunda has a more flexible reaction system than that of I. anisatum.
To give a improved cultivation technique to the farmers, we also have conducted some studies on the effect of several nutrition treatments. And we Now we have the propagation nursery of favorable trees that could be distributed to the farmers.
