Karakterisasi Morfologi Polen Tiga Jenis Mangga (Mangifera)

Abstract

One of the largest mango diversity center in the world is Indonesia. Taxonomically, three types of Mangifera namely M. Laurina, M. indica and M. sumatrana require better proof to obtain more certainty of taxonomic status. The source of taxonomic evidence that can clarify the taxonomic status of the three types Mangifera is characters of pollen morphology because it is unique and pollen of different plants has a different shape, size and wall-type of pollen. This research was conducted from November 2020 to March 2021. Sampling was conducted around Pekanbaru and Kampar areas, Riau Province. The pollen observation was conducted in the Botanical Laboratory of the Department of Biology, Faculty of Mathematics and Natural Sciences, Riau University. Results of the study obtained 5 polen characters. Similar properties of morphological characteristics of pollen are monad polen unit, polar view angular, equatorial view circular/oval, polarity polen isopolar, while the differences were found in size and shape of the pollen. The character of the size and the shape of the pollen can contribute as one of the distinguishing characters among the three types of Mangifera
