PERBANDINGAN KARAKTER MORFOLOGI ANGGREK VANDA SPESIES BALI DAN YOGYAKARTA

Abstract

Vanda orchid is one of the orchid species developed in Indonesia, especially in Bali and Yogyakarta, where currently the population has decreased due to various natural and social factors that require serious handling. To find out the differences of Vanda orchid plants in Bali and Yogyakarta, morphological characterization is one of the efforts to find out the diversity of orchid plants in terms of growth, shape, and appearance. The research was conducted in Bali from July to August 2023, and in the Biotechnology Lab, Faculty of Biology, Gadjah Mada University from September to December 2023. The research began by characterizing adult orchid plants morphologically which included; plant height; internode length; stem diameter; leaf length; leaf width; number of leaves; flower diameter; flower stalk diameter; flower stalk length; and number of flowers per stem. Based on the results of morphological characterization research found 6 types of orchid plants, namely: V. tricolor lindl. Var suavis Bali, V. tricolor lindl. Var suavis Merapi, V. limbata Bali, V. limbata accession Yogyakarta, V. helvola Bali, and V. helvola accession Yogyakarta. Morphologically these 6 orchid plants look the same, but there are parts that can be used as a differentiator that can be seen in the leaves and flowers.
