Abstract. Berame J, Lawsin N, Miguel F, Chavez J. 2020. Morphological variations of mangosteen fruits from Luzon and Mindanao Islands, the Philippines. Biodiversitas 21: 3094-3100. Luzon and Mindanao islands in the Philippines are the important mangosteen producing provinces whose growing areas are scattered on these two islands. With this, mangosteen variability was detected based on field fruit collections in summer of 2019. The morphological variations of mangosteen fruits were observed and collected in Quezon Province in Luzon and Davao-Zamboanga Provinces in Mindanao based on the total number of 175 mangosteen trees. The main objectives of the research were to find out the morphological variations of mangosteen fruits and using Tomato Analyzer 4.0 to determine the morphological characters that can be used to differentiate mangosteen accessions in the Philippines. The variables include fruit shape index (external and internal), curve fruit shape index, asymmetry, internal eccentricity and weight of the ripe fruits. The results show that fruit characters like ellipsoidal, circular, rectangular, lobe shape, size, pericarp area, and pericarp thickness. are highly resemblance particularly in its fruit shape characters, and even sharing a similar taste of ripe fruits. Data revealed that Garcinia mangostana shared a similar character with Garcinia malaccensis even though they are from different geographical areas. Based on the morphological variations and characters, the two varieties of mangosteen fruits in the Philippines, G. mangostana and G. malaccensis, are so closely related that they could be combined together as one species as identified in the morphological analysis of this study.

Potential development of mangosteen (Garcinia mangostana L.) through optimizing land use in Pati, Central Java, Indonesia

“…Fruit measurement is a procedure for measuring the parameters of pointed and round fruit based on their diameter and weight [36]. Mangosteens have diverse weights (Tabel 3).…”

Economic Efficiency and Circular Economy of Corchorus olitorius L. and Garcinia mangostana as Natural Coagulants in Domestic Wastewater Treatment

“…for various purposes ranging from usage in industrially important products to applications to advance technology (Aizat et al, 2019). Luzon and Mindanao are considered the two highest important mangosteen-producing islands in the Philippines (Berame et al, 2020). This crop can produce 2,000 -3,000 fruits per tree when properly fertilized, pruned, and irrigated (Ramage et al, 2004).…”

Deciphering the Analysis of the Genetic Diversity of Mangosteen (Garcinia mangostana L.) from Various Regions of Origin in Java, Indonesia

“…In reality, mangosteen has variations in both phenotype and genetically 6 . Previous publications have described the presence of morphological variations in mangosteen in North Sumatra, Indonesia 7 , and the Philippines 8 . Moreover, genetic variations of some mangosteen accessions have been detected with microsatellite markers [9][10][11] .…”

“…Efforts to improve the approaches of G.mangostana L. have been carried out, including splicing techniques between mangosteen and its close relatives in other Garcinia genera, which aims to shorten the juvenile period 16 . Efforts to produce superior clones have also been made with gamma-ray irradiation 8 . A plant's genetic repair program to produce highyielding varieties relies heavily on the availability of sources of genetic diversity 17,18 .…”
