Structure and germination pattern mangosteen seed (Garcinia mangostana L)

Abstract

Mangosteen is one of the most famous tropical fruits. In addition, mangosteen is also used as medicine, including as an anti inflammatory, antibacterial. Mangosteen is apomyxic so that plants that come from seeds will be genetically similar to their mother. Apomixis is an asexual method of reproduction through seeds where seeds are formed without reducing chromosome numbers and fertilization. Polyembrioni is the event that there are more than one embryo in one seed. Seed structure is a component of a seed that has different functions with the aim of breeding plants. The structure of the plant seeds that must be known is the seed as a reproduction tool, the spread, and the survival of a plant. In addition, for seed plants, seeds are the beginning of new plant life outside the parent.Results showed that mangosteen seeds had polyembryonic properties which had more than one embryo scattered around the embryo axis. The structure of the mangosteen seeds consists of testa, endosperm and embryo axis and after the seeds are planted for 7 days there appears a red line (Micropyle) from the shaft of the embryo to exit the seeds which will become buds. Mangosteen seed germination begins with the appearance of red colored buds that come out randomly around the surface of the mangosteen seeds sourced from the embryo axis, then after a few days red plumules appear and are followed by the appearance of radicles.
