Abstract

Melona, Tacapa Gold, and Gama Melon Parfum are novel Melon genotypes that have been introduced for cultivation in the saline-prone coastal region of Bocor Beach, Kebumen, Central Jawa. Elevated salt concentrations in the area pose challenges, impacting yield. The potential of these new genotypes for saline land remains unexplored. This study aimed to assess the morphophysiological and molecular responses of these genotypes to salinity stress. Seeds were germinated in cocopeat and ABmix 3000 solution and treated with 220 mM NaCl until harvest. The analysis included morphology, chlorophyll content, proline accumulation, malondialdehyde levels, and gene expression were analyzed. After 1 week of salinity stress, the results showed reduced plant height, leaf number, stomatal density, percentage of opened stomata, and width and length of leaves. The malondialdehyde, proline, and root-shoot dry mass ratio increased. The expression of CSD1-1, P5CR, and late embryogenesis abundant genes increased under salinity treatment. Gama Melon Parfum exhibits salt tolerance, as indicated by higher P5CR gene expression, proline accumulation, and leaf-relative water content. P5CR gene expression, proline accumulation, and leaf-relative water content are valuable indicators of salt tolerance for assessing melon genotypes.

Abstract

Sinduadi Village, located in Mlati Subdistrict, Sleman Regency, Special Region of Yogyakarta, Indonesia, is home to several active horticultural farmer groups. Among their commodity crops, longan cultivation in Sinduadi Village has faced persistent constraints, particularly low productivity. To address this limitation, a community service program was initiated to introduce a superior local variety, the ‘Sleman’ longan. This cultivar was developed through sustained research and breeding by the Laboratory of Genetics and Breeding, Faculty of Biology, Universitas Gadjah Mada (UGM). Stingless bees, locally known as klanceng bees, play an important role as pollinators in horticultural systems. Integrating longan cultivation with stingless beekeeping as a managed pollination strategy is expected to improve longan productivity and support more sustainable farm management. The program applied a comprehensive capacity building approach, including lectures, extension sessions, hands-on training, and regular monitoring. These activities aimed to strengthen both conceptual understanding and practical competence related to cultivation of the ‘Sleman’ longan variety and stingless beekeeping management. The program resulted in an observable improvement in participants’ knowledge and skills within the Sinduadi Village farming group. Improvements in farmer capacity will be evaluated through continued monitoring of field practices and performance over time. Although short-term gains in yield have not yet been observed, substantial longer-term benefits are anticipated as the plants establish, adapt, and enter stable production. Overall, this knowledge transfer is expected to empower the community to address local agricultural constraints more independently and to promote sustained improvements in livelihood and well-being.
