Abstract

Phalaenopsis amabilis is an Indonesia native orchid species having large, white flowers with yellow labellum coloration. This studies aimed to develop Phal. amabilis micropropagation methods and evaluate the regenerated plantlet fidelity. Media supplemented with Thidiazuron (TDZ) and Polyvinylpyrrolidone (PVP) and medium pH adjustment effects to induce protocorm-like bodies (PLBs) from leaf explants and proliferate secondary PLBs were investigated. Clonal fidelity among regenerated plantlets was evaluated using eighteen SNAP marker loci. The results showed that the ½ MS medium supplemented with 3 mg L-1 TDZ and 0.5 g L-1 PVP was the best for PLB induction while the ½ MS medium supplemented with 0.5 mg L-1 TDZ was the best for PLB proliferation. For PLB induction, the media pH was adjusted into pH=7 for efficient PLB regeneration. Based on the assessment using 18 SNAP marker loci, four variant alleles in three loci (11.8%) out of a total 34 plantlets were detected. The mutation frequency at the evaluated SNAP marker loci was 2.5 x 103 (0.25%). Changes in SNP alleles may not always result in phenotype changes and allele variant occurrences may not affect phenotype fidelity of micro-propagated Phal. amabilis plantlets. Therefore, further studies about the phenotype fidelity among plantlets are necessary.

Abstract

One of the agricultural public commodities in Indonesia which still cannot fulfill its domestic consumption needs is soybean. The objectives of the research, which was conducted in Karawang Regency, West Java, Indonesia, were to: (i) identify the suitable area for soybean plantations in paddy fields, (ii)  assess the development of soybeans in land use and socio-economic context, and (iii) plan the spatially soybean plantation. A soil survey and land evaluation for soybean was completed. IKONOS imagery was applied to delineate paddy fields while a dynamic system modelling was developed using Powersim 8.0 software. The results of the research showed that the suitability class for soybean plantation in the paddy fields of Karawang Regency ranges from unsuitable (N) to suitable (S2), with limiting factors being temperature, fertility, nutrients retention, slope, erosion, rooting media and toxicity. Very limited arable land  has been used so far for soybeans plantations due to low economic returns. The model predicts that, should the development of soybean continues in its business as usual path, a deficit of soybean will occur in 2030. The model provides alternative scenarios to reduce the deficit. Prioritization was done spatially using the suitable land gradually, corresponding to the government budget availability.
