Abstrak: Chlorophyll is the primary photosynthesis pigment of plants. The level of chlorophyll content of plant can be affected by external factors, such as light, temperature, and carbon dioxide. Karst is a unique topography that formed by water flow on carbonate rocks. One of the plant that can be found in the karst ecosystem was Prunus avium. Prunus avium is a major species of karst ecosystem. The purpose of this research was to determine the level of chlorophyll and leaf area index (LAI) in Prunus avium at the different influence of altitude and environmental factors. The level of chlorophyll was measured by SPAD Chlorophyll meter in each altitude on the same characteristic of Prunus tree. The results showed that the chlorophyll was inversely with altitude, LAI and environmental factors. The highest level of chlorophyll that found at 175 mdpl of altitude was 34.32 and the lowest 355 mdpl of altitude was 25.18. LAI showed the highest values 3.32 at 355 mdpl. Based on the statistical analysis, the environmental factors that affected the level of chlorophyll are light intensity, temperature, humidity and wind speed (p<0.05).

Abstrak: Plants in Karst Area have different characteristics and distinctive when compared with plants of other forest ecosystem. The purpose of research is to assessing the composition and stand structure and root system of plants in karst areas in Bantimurung-Bulusaraung National Park, Resort Pattunuang-Karaenta. This observation plots determined by purposive sampling based on the representation of the stand. Three sample plots lines with the size of 20 m x 100 m each were constructed in the research site. The research was spread out on four habitats that are on hill base, slopes, summit with considerable soil cover, and summit with very little soil cover. The number of species on the research area is amounted 108 species of seedlings and understorey plants, 108 species saplings, 63 species poles and 78 species trees. Horizontal structure inverted J-shaped and vertical structure of the stand consist of four strata (B, C, D, and E strata). Overall, the spatial distribution patterns have a clumped distribution pattern. Uniform distribution pattern is only found in Palaquium obovatum species of pole on slopes and Dracontomelon dao species of tree on base. Pterospermum celebicum has the highest value of shoot-root ratio on the hill base, index root binding highest value with category of moderate (1.5-3.5) on hill base and index root anchoring highest value with the high category (>1.0) on summits with considerable soil cover.
