Xylaria nigripes is a rare medicinal mushroom in the Xylariaceae family, which has long been used in traditional medicine to aid in treating conditions such as insomnia, neurasthenia, and inflammation. This fungus usually grows in an environment characterized by termite nests. Recent studies have shown that X. nigripes contains many valuable biological compounds such as polysaccharides, nucleosides, and sterols, which provide important biological effects, such as antioxidants, liver protection, immune system regulation, and diabetes treatment. In addition to pharmacological potential, many research works have focused on developing X. nigripes biomass kernel techniques under artificial culture conditions, in order to optimize growth and accumulation of active ingredients. These results not only contribute to clarifying the application potential of this mushroom in the pharmaceutical field but also create a scientific foundation for the sustainable exploitation of this rare medicinal resource.

The Stripe ebony tree (Diospyros frutescens Blume) is considered a species in danger of extinction due to overexploitation. Therefore, there is an urgent need to regenerate and conserve the species for future generation. In this study micropropagation protocol of Diospyros frutescens Blume was developed using nature zygotic embryos. Zygotic embryos isolated from germinated on MS medium containing 0.4mg L-1 Kinetin + 1.0mg L-1 BA. There were (83.11±0.79%) of explants induced shoots after 30 days of culture. The highest number of shoot on 1/2 MS medium supplemented with 2.5mg L-1 BA + 0.6mg L-1 IBA was 5.84±0.035 shoots per explant after 45 days of culture. The percentage of shoot produced roots the highest 85.52±0.48% after 45 days culture on 1/2 MS medium contain 0.8mg L-1 IBA

Tourism is one of the strengths of Phu Yen province. This study was conducted the method of aseessing the potential and exploition value of in a tourist and recreational context in Tuy Hoa City. This potential was explored throughout a range of criteria in terms of aesthetic, scientific, historical, economic values, degree and modality of exploitation. The results showed that the score of tourism potential value in Tuy Hoa City is quite average at 0.5 points. However, the score of tourism exploitation capacity in Tuy Hoa city is at a low level of only 0.36 points. That means Tuy Hoa City has not yet exploited the inherent tourism potentials to promote tourism development in the locality.
