ANALISIS HUBUNGAN KEKERABATAN BEBERAPA JENIS MANGGA (Mangifera) BERDASARKAN KARAKTER MORFOLOGI DAN FLUORESENSI KLOROFIL

Abstract

This study aimed to characterizeand to determine mango species of Mangiferabased onthe morphological character and laser induced fluoresence of chlorophyll. The study had been conducted from December 2012 to March 2013 on 4 study sites in Riau Province by using a survey method anda direct observationto the morphological characters and a simple method to the fluoresence of chlorophyll. Data of morphological observation and fluoresence of chlorophyll was described in a character tabel. A total of 80morphological characters and fluoresence of chlorophyll were scored and analyzed using PAUP 4.0. 9 distinct mango species from Mangifera genus were determinedbased on the morphological characters and fluoresence of chlorophyll. The cladogram formed two main clads, clad I only consisted of M. torquendra and clad II consisted of M. foetida, M. odorata, M. indica, M. laurina, M. sumatrana, M. zeylenica, M. quadrifida and Mangifera sp.. All of the Mangiferaspecies in clad II were grouped with bootstrap value at 51%. The clustering result in the cladogram was mainly based on the similarity of morphological characters and the similarity of fluoresence colors.
