THE VARIABILITY OF Lansium domesticum Corr. (DUKU) ACCESSIONS BASED ON THE CHARACTERS OF MORPHOLOGY, PHYSIOLOGY AND ANATOMY IN MUSI RAWAS REGENCY, SOUTH SUMATRA INDONESIA.

The research was aimed to examine morphological, physiological and anatomical characters of Lansium domesticum Corr. (duku) accessions from three locations in Musi Rawas Regency, South Sumatra Indonesia. The experiment was carried out from February to April 2016. The physiology and anatomy analysis were carried out in the Laboratory of Plant Physiology, Department of Agronomy, Faculty of Agriculture, Sriwijaya University, South Sumatra. The methodology used was direct survey and observation strikethrough. Based on the results of research in Musi Rawas Regency to the morphology, anatomy and physiology characters of duku gained wide variability of phenotypic diversity on leaf color, leaf area, plant height, stem girth, number of abaxial stomata, and leaf chlorophyll, while the other variables (leaf length, leaf width, number of adaxial stomata, leaf sucrose, leaf total N, leaf shape, leaf venation, leaf edge, leaf base, leaf tip, branching type, and type of stomata) had a narrow variability. Based on genetic relationship gained two large groups with the value diversity between the accession of 50%. [ABSTRACT FROM AUTHOR]
