Abstract: The light intensity
influences to morphological and anatomical characteristics of plant leaves in
the process of plant growth. The objective of this study was to know
morphological and anatomical characteristics of the seedling plant leaves in
the different light intensities. The study was conducted in Education Forest of
Forestry Faculty of Mulawarman University. The three study sites were selected
to represent heavy, moderate, and little light intensities, respectively. The
vegetation survey was done in 20 quadrants of 2 m × 2 m in three different
light intensities. The analyses of morphological and anatomical characteristics
were done to leaves of most five dominant species based on Important Value
Index (IVI) in each study site. The morphological characteristics of seedling
leaves in heavy, moderate, and little light intensities were leaves length of
13.4 cm, 13.9 cm, and 16.5 cm; leaves wide of 5.0 cm, 5.4 cm, and 6.1 cm, and
leaves thick of 0.09 mm; 0.08 mm, and 0.06 mm, respectively. While anatomical
characteristic of chlorophyll content of seedling leaves in heavy, moderate,
and little light intensities were 45.5%, 46.0%, and 42.7%.
