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.

Porang merupakan salah satu komoditas tanaman yang sangat potensial dan prospektif untuk dilakukan pengembangan. Namun dalam kegiatan budidaya masih terkendala dalam penyediaan bibit porang yang kurang sehingga produksi tidak bisa memenuhi permintaan ekspor. sistem regenerasi porang secara in vitro menjadi salah satu alternatif dalam mendukung terhadap upaya produksi bibit porang secara masal serta pemuliaan dengan bioteknologi. Tujuan dilakukannya penelitian ini adalah dalam upaya mendapatkan metode regenerasi porang secara in vitro yang optimal, baik melalui jalur organogenesis maupun embriogenesis somatic memakai eksplan daun dan dengan perbedaan konsentrasi dan jenis ZPT. Penelitian ini dilakukan dengan analisis deskriptif dan visual. Adapun hasil yang didapatkan perlakuan penggunaan ZPT dengan perlakuan K2 dapat merangsang regenerasi eksplan secara somatik embryogenesis dan pemberian ZPT dengan perlakuan K4 dapat merangsang regenerasi eksplan secara organogenesis dengan kecenderungan terbaik .
