In vitro cultured and supply chain porang in South Sumatra

Abstract

The objectives of the study are first, farmers in P4S Karya Tani can obtain superior porang seeds by regenerating porang in vitro culture through organic plus liquitermy fertilizer. Second, analyzing the media for growing tissue and the concentration of each porang plant media in P4S. Third, analysis of the supply chain structure of porang in P4S. This study uses quantitative and qualitative approaches with simple randomized design methods and SCOR methods. Based on the experiment, vitro culture of porang in P4S using liquitermy fertilizer, there were nineteen out of thirty porang plant accessions which had the potential as new clones for seedlings with an average tuber of 6.00-99.88% larger than the parent. The porang supply chain in P4S needs to be developed by involving wider stakeholders. This study shows that the seed production rate is better with liquitermy fertilizer in the porang in vitro culture. However, further evaluation is needed in analyzing genetic traits and glucomannan levels.
