STRUKTUR ANATOMI DAUN, KANTUNG DAN SULUR NEPENTHES GRACILIS KORTH. YANG TUMBUH DI AREA INTENSITAS CAHAYA BERBEDA
ABSTRACT: Sunlight is one
factor that plays a major role in the process of the plant physiology. Plants
will go through a variety of morphological and anatomical changes in order to
be able to adapt to the environment with varying light intensity. This research
aims to know the anatomical structure of leaves, foliage and Nepenthes gracilis
Korth. tendrils which grow in areas with different light intensity. The
research was conducted from May 2014 to September 2014. The paraffin method is
used in making preparations of transverse incision of leaves, foliage, and N.
gracilis tendrils. The results of the study on the transverse incision of the
leaves, foliage and tendrils growing at different light intensity indicated a
difference in the thickness of the epidermis, stomata number, thickness of
cortical cell layers and size of the vessel. N. gracilis that were grown in the
shaded area had thinner epidermal thickness of leaf which was 3.24 ± 0,48μm
than those grown in an open area which was 6.59 ± 1,35μm. The number of stomata
grown in a shaded area was fewer i.e. 44 compared to that grown in the open
area which was 84. The thickness of the cortical cell layers of tendrils grown
in the shaded area was thinner which was 155.30 ± 2.79 μm than those grown in
an open area that was 176, 49 ± 4,23μm and the size of the vessel on the leaves
and tendrils grown in the shaded area was smaller than those grown in an open
area.
