Abstract

Light intensity in plants influences their growth potential as well as their morphological, anatomical, and physiological structures. This study aimed to observe the leaf area, leaf thickness, leaf type, stomatal type, stomatal density, chlorophyll content, and phytochemical content of Sente leaves (Alocasia macrorrhizos) in two locations with different light intensities. This exploratory research used a survey method to determine the research location, and environmental parameter measurements was used as supporting data. Morphological and anatomical parameters and chlorophyll content were assessed using a quantitative approach, while phytochemical content was determined qualitatively and analyzed descriptively. The results showed differences in the morphology, anatomy, chlorophyll content, and phytochemicals of Sente leaves in varying light intensities. Morphologically, the leaves of Sente plants in shaded locations had larger surface areas, were thinner, and appeared greener compared to those in unshaded locations. The stomatal density of leaves in unshaded areas was higher (76.43 cells/mm ²) compared to shaded areas (56.05 cells/mm ²). The chlorophyll content in shaded locations was higher (82.03 CCl) than in unshaded locations (41.7 CCl). Phytochemical tests for flavonoids and saponins showed higher compound levels in leaves from unshaded locations, while tannin tests revealed higher levels in shaded locations compared to unshaded ones. Meanwhile, tests for alkaloids and quinones yielded negative results.

Abstract

This study examines the stomatal characteristics and leaf thickness of six species within the Liliales: Gloriosa superba, Sansevieria trifasciata, Aloe vera, Cordyline terminalis, Pleomele angustifolia, and Allium fistulosum. Stomatal density, type, and distribution were measured to understand their relationship with leaf morphology. The results show that Gloriosa superba has a stomatal density of 148.72/mm² and an index of 0.295, with thin leaves. Sansevieria trifasciata, with its thick, fleshy leaves, has a lower stomatal density of 15.39/mm² and an index of 0.031. Aloe vera, another species with thick leaves, has a stomatal density of 38.47/mm² and an index of 0.067. In contrast, Cordyline terminalis and *Pleomele angustifolia, which have thin leaves, exhibit higher stomatal densities of 192.31/mm² and 128.21/mm², respectively. Their stomatal indices are 0.092 for Cordyline terminalis and 0.163 for Pleomele angustifolia. Allium fistulosum also has thin leaves, with a stomatal density of 100/mm² and a high stomatal index of 0.390. The study reveals that species with thicker leaves tend to have lower stomatal densities, a feature that helps reduce water loss in arid environments. These findings contribute to a deeper understanding of plant adaptation mechanisms and have implications for improving water-use efficiency in agriculture and conservation efforts.

Abstract

This study aims to compare the salt content (NaCl) in the leaves of several types of coastal plants that grow in different formations, namely Mangrove, Barringtonia, and Pres-Caprae. The study was conducted in the coastal area of Lais District, North Bengkulu Regency using direct survey methods in the field and laboratory analysis using a refractometer. The results showed that there were 10 species of coastal plants from three formations, namely Barringtonia, Mangrove, and Pes-Caprae. The highest salt content was found in the Acanthus species ilicifolius (2.75‰) from the Mangrove formation, while the lowest levels were found in Canavalia maritima (0.75‰) from the Pes-Caprae formation. The difference in salt content is thought to be influenced by the location of its habitat in the coastal area and its ability to adapt both structurally and physiologically so that it can survive in an environment with extreme salt content. The results of this study provide important information about the adaptation of coastal plants to salinity and can be the basis for further research on salt concentration in coastal plants.

Abstract

This study investigates the phytochemical content and morpho-anatomical characteristics of Celosia argentea L. plants grown under different light intensities in the Embung Leuwi Padjadjaran area. Leaf samples were collected from shaded and unshaded locations to compare their responses to varying light conditions. Phytochemical analysis revealed that plants in higher light intensity areas tended to have increased levels of specific phytochemical compounds, which is crucial for the plant's defense mechanisms. Furthermore, the research found morphological and anatomical differences, such as greater leaf thickness and a lower stomatal density in unshaded plants. Conversely, shaded plants exhibited higher chlorophyll content and larger leaf areas, which are adapted to low-light environments. The study concludes that varying light intensity significantly influences the morpho-anatomical features and phytochemical composition of Celosia argentea L., with shaded conditions promoting adaptations for light capture and unshaded conditions increasing certain phytochemicals and leaf thickness.
