Knowing the genotypes of and its fiber production properties is key for developing cultivars with homogeneous properties and focusing on specific products or market segments that generate added value to the fiber. For this reason, the objective was to determine the optimal use of five genotypes of (MT01, MT03, MT07, MT11, and CF01) with high productivity grown in the tropical region of Costa Rica. Therefore, anatomical, physical-mechanical, chemical, and energetic analyses were carried out on these fibers to define whether any genotype has the ideal conditions for a specific use. The results showed differences between the genotypes, obtaining significant differences in physical-mechanical properties (tension, water retention, and color), chemical properties (holocellulose, lignin, extractives, and elemental values of nitrogen, carbon, and sulfur), and energetic properties (volatiles, ash, and caloric value thermogravimetric analyses), which resulted in the establishment of two groups of genotypes with a dissimilarity degree of 35%. The first group, composed of MT03 and MT01, presented characteristics suitable for paper production, biodegradable materials, and composite materials. On the other hand, the second group, made up of MT07, MT11, and CF01, showed properties suitable for textiles, heavy-duty fibers, and bioenergy.
了解[植物名称]的基因型及其纤维生产特性是培育具有均匀特性的品种以及专注于能为纤维带来附加值的特定产品或市场细分领域的关键。因此，目标是确定在哥斯达黎加热带地区种植的五种高产[植物名称]基因型（MT01、MT03、MT07、MT11和CF01）的最佳用途。为此，对这些纤维进行了解剖学、物理力学、化学和能量分析，以确定是否有任何基因型具备特定用途的理想条件。结果显示各基因型之间存在差异，在物理力学性能（拉伸、保水性和颜色）、化学性能（全纤维素、木质素、提取物以及氮、碳和硫的元素值）和能量性能（挥发性物质、灰分和热重分析的热值）方面均获得了显著差异，这导致建立了两组基因型，其差异度为35%。第一组由MT03和MT01组成，具有适合造纸、可生物降解材料和复合材料的特性。另一方面，第二组由MT07、MT11和CF01组成，显示出适合纺织品、重型纤维和生物能源的特性。
