Struktur Anatomi Batang Tiga Jenis Rotan Genus Calamus Dari Kawasan Tembawang Kabupaten Kubu Raya
Abstract: Rattan΄s stem , is used to make furniture and ropes. The strenght of rattan is
stem classified according to vessel arrangement
an dimensional fibre.
The purpose of
the research was
to investigate anatomical structure of three types of rattan
stem, namely worm rattan (Calamus asperimus Bl), sega rattan (Calamus caesius
Bl), and semambu rattan (Calamus scipionum L). The research was conducted by
using embedding and maceration method. According to transversal from these
three types of rattan showed peripheral and central corpus area. Cortex belongs
to type A that is “jigsaw puzzle like”
with characteristics large cells, irregular inform
with numerous large intercellular spaces. Vascular tissue has colateral
type which consists of xylem and floem
surrounded by fibers. Protoxylem of C.
asperimus and C. caesius contain 1-6 cells and C. scipionum has 2-10 cells with loose arrangement.
Metaxylem has round shape and has one
composition in the centre of vessel. The mean of metaxylem diameter from
each species (C. asperimus, C. caesius
and C. scipionum) was
130,4 µm, 194,0 µm and
300,5 µm respectively.
Floem consists of
two areas which contain
3-4 cells and
has sequential structure.
Dimensional fibre has
various value depend
on early cell development, stem position and age stem.
