Histology Study of Aquilaria malaccensis and the Agarwood Resin Formation under Light Microscope

Abstract

ABSTRACT

A histology study was conducted in the investigation of the anatomy of Aquilaria malaccensis cell structures and the organelles existing in the plant system to seek for the correlation between the cell structure and the response of resin secretion and accumulation in the plant cell system. Light microscopy was used in the study due to its simplicity in the sample preparation and the power of visualization gave a clear image of the cell structure. The xylem cell structure was investigated under light microscope to seek for the answer of the agarwood resin formation and accumulation in the A. malaccensis caused by the responses of the cells towards the defense system trigged by an injury or the invasion of microbes.

Keywords: Aquilaria malaccensis, resin formation, xylem cell

ABSTRAK

Kajian histologi telah dijalankan ke atas anatomi struktur sel dan organel Aquilaria malaccensis yang wujud dalam sistem pokok tersebut untuk mengkaji hubungan antara struktur sel dan tindakbalas rembesan dan pengumpulan resin dalam sistem sel tumbuhan. Dalam kajian ini, mikroskop cahaya telah digunakan berdasarkan kepada cara penyediaan sampel yang mudah dan kuasa visualisasi struktur sel yang jelas. Sel xilem telah dikaji dengan menggunakan mikroskop cahaya bagi memahami penghasilan dan pengumpulan resin gaharu dalam A. malaccensis disebabkan oleh rangsangan terhadap sistem pertahanan yang terpicu oleh kecederaan atau infeksi mikrob.
