Morphological Characteristics and Pollinia Observation of 10 Indonesia Native Dendrobium Orchids

Abstract

Characterization of native orchid (species) in Indonesia is important for preservation of germplasm and selection process to obtain dominant character of orchids as potential parental. Morphological characterization is a method to obtain scientific information in phenotypic manner. Characterization of plants was carried out on 10 native orchids of Dendrobium genus to obtain specific character. Characterization process based on UPOV guidebook and morphological observation of pollinia was also carried out on 10 native orchids to obtain information about the structure and physiology of pollinia. The results of morphological characterization on 10 native orchid showed several qualitative characters such as flowering position, cross section of leaf, pseudobulb firmness, and leaf arrangement in D. Canaliculatum was different from 9 other native orchid. Morphological pollen of 10 native orchid shows the diversity structure of pollinia and the physiological conditions of mature pollen which are ready to pollinate are pollinia with a golden yellow colored. Knowledge and information about parental relationships is the main point for developing ornamental plant breeding programs. Selection of native orchids as potential elder is important where selected elders will be used as a source of genetic diversity. The results of this study are expected to provide scientific information and phenotypic selection for the development of hybrid orchids.

Morphological characteristics of Phaius spp. orchids from Indonesia

“…The determination of morphological characters was carried out on plant parts, namely stems, flowers, leaves, roots, seeds, and fruit, which were identified and documented (Indraloka et al 2019). Leaves on orchids have several variations from elongated round to roundedlike in general, lacked leaf bones that form a spread mesh, however parallel to the blade.…”

“…Morphological characterization in orchids is also very important in breeding efforts for conservation and agribusiness purposes (Kasutjianingati and Firgiyanto 2018). The characterization result of 10 native Dendrobium orchids having a place to spatulata segment in Indonesia can be utilized as logical data for many requirements in cross-breeding movement, propagation, conservation of germplasm and hereditary change (Indraloka et al 2019).…”

Short Communication: Diversity and distribution of epiphytic orchid Dendrobium section Spatulata on the host plants in the Cycloop Mountain Nature Reserve of Papua, Indonesia

“…Up to 41% of the revised species are listed as growing within the CMNR area. Other studies using morphological approaches (Metusala 2019), flower and fruit anatomy (Indraloka et al 2019), including the publication of orchid species in reference books (Handoyo 2021;Schuiteman 2013) and the colonization of mycorrhiza in orchid roots (Nurfadilah et al 2016) also add complexity to the diversity of this section. This complexity was notified more than a decade ago by Kraenzlin (1910).…”

Identification of <i>Dendrobium</i> (Orchidaceae) in Liwa Botanical Garden Based on Leaf Morphological Characters

“…Tropical Biodiversity Biotechnology (CC BY-SA 4.0) one day to more than 30 days and each stem can have one to more than 20 flowers. Many Dendrobium grows at locations with an altitude less than 400 meters above sea level (Pang et al 2012;De et al 2015;Darmawati et al 2018;Indraloka et al 2019;Zahara & Win 2019;Yuan et al 2020).…”
