Diversity of morphological characters of 30 local torch ginger accessions from Pangandaran of West Java of Indonesia

Abstract

Torch ginger (Etlingera spp.) is one of the herbal plants native to Indonesia that has long been known and used as medicines. Exploration on torch ginger plant needs to be done to conservate and determine genetic diversity. Study of genetic diversity torch ginger in the district of Pangandaran is important because as long as there has been no study in depth the potential of genetic diversity and phylogenetic relationship germplasm of torch ginger Genetic diversity based on this research had a proportion of 47% of the total of 100% in the PC1-PC3 was based on the analysis Principal Component Analysis (PCA) with the character influencing that form clumps, line leaf midrib, plant height, stem diameter, leaf length, color scales rhizome, stem color, rhizome and the leaf base forms. Based on the results of the genetic diversity cluster analysis found that narrow torch ginger euclidean indicated by coefficient of 0.79 and was divided into six clusters. Accession which had the closest kinship i.e. accession N1 from Cikadu subdistrict of Cintakarya and accession N2 from Cikoang subdistrict of Cintakarya, while accession with the farthest kinship namely accession N29 from Jangraga subdistrict of Mangunjaya with range euclidean of 0.79.

Analysis of the diversity of local ginger (Zingiber officinale Rosc.) in Pandeglang Regency, Banten Province based on morphological characteristics

“…The difference between the two types of ginger was based on the appearance of the color of the outer surface and the aroma on the rhizome. The surface on ginger emprit is brownish yellow and the aroma does not sting while the red ginger is reddish and pungent [9].…”

Medicinal Plant Drying Using a Superabsorbent Polymer Dryer Incorporated with an Insulated Heater

“…The drying air entering the drying cabinet was controlled to give a temperature of not more than 60 • C. The medicinal plant materials investigated in this work included turmeric, ginger, greater galangal, Curcuma, and lesser galangal. The selection of turmeric, ginger, greater galangal, Curcuma, and lesser galangal was due to the availability of these medicinal plants in Indonesia [22][23][24][25]. In addition, their high contents of bioactive compounds also convinced us to use these medicinal plants as the samples in our study [26][27][28][29].…”
