摘要

Bamboo, considered the "green gold," has attracted world attention as a green substitute for the traditional materials because of its fast growth, renewability, and mechanical properties. In this first-ever study, we present the creation and holistic characterization of a new hybrid bamboo, BH-1⚥ (Bambusa alamii ♀ × Gigantochloa nigrociliata ♂), the first of its kind to be scientifically designed and cultivated at KSCSTE–Jawaharlal Nehru Tropical Botanic Garden and Research Institute (JNTBGRI), Kerala, India. Both the parent species and their hybrid combination were analyzed microstructurally in detail to assess anatomical differences and structural integration. The hybrid was tested under a multi-disciplinary analysis consisting of physical, chemical, thermal, tensile, and morphological tests, with comparison to its parental species. The hybrid exhibited a crystallinity index of 72.18% and larger crystallite size (2.73 nm), indicating improved structural order. It showed greater thermal stability (Tmax: 370 °C) compared to both parents. Density was 0.96 g/cm3 with reduced moisture content (4.81%) and limited water absorption (41% at 60 min), enhancing dimensional stability. Tensile strength (325.1 MPa) and tensile modulus (69.51 GPa) were markedly higher than the parent species, representing increases of 42.4 and 50.6%, respectively, while tensile strain decreased, confirming the hybrid’s harder and more resistant fibre nature. SEM observation of broken fibre surfaces showed a dense, uniform fibre structure with clean fractural patterns, ascertaining its superior inherent morphology. The findings place BH-1⚥'s colossal potential as an eco-friendly, high-performance material for use in construction, composites, bioplastics, packaging, textiles, and automotive parts. The success of this hybrid bamboo not only enriches our knowledge in bamboo breeding but also provides new opportunities for tissue-cultured propagation and commercial utilization, supporting India's green development and meeting world demand for green biomaterials. This paper therefore introduces BH-1⚥ as a model hybrid bamboo, connecting nature, science, and industry towards a greener future.
