ABSTRACT Introduction Previous studies showed that biochar amended soils significantly enhanced the growth and yield of quinoa under water limitations. So it becomes an emerging agronomic strategy to consider for sustainable production. Biochar can specifically be considered area particularly receiving low annual rainfall more vulnerable current climate change conditions. Materials Methods A field experiment was conducted using variety INIA 415 Pasankalla, employing a factorial design assess effects different application rates made municipal pruning waste agricultural (0, 1, 2, 3 t·ha⁻¹), three irrigation intervals (irrigation every 5 days, 10 15 days). The volumetric soil moisture content, hydraulic properties, quinoa's biometric characteristics components were evaluated. Results results indicated longest (10 days) resulted in levels between 19% 40% below wilting point (soil matric potential: −1.5 MPa), creating stress However, increased capacity from 0.31 0.38 g H₂O g⁻¹ soil, raised air content 22% 29% at irrigation, promoted absorption point. Furthermore, t·ha⁻¹ yield, increasing 3.18 4.22 t·ha⁻¹, along with improvements leaf area, total biomass, root length, panicle length by 70.74%, 76.54%, 14.34%, 16.55%, respectively. Conclusions It concluded mitigated negative caused prolonged intervals. This treatment improved soil's physical properties enabled Pasankalla achieve yields close its theoretical productive potential.

High-altitude plants face extreme environments such as low temperature, oxygen, nutrient levels, and strong ultraviolet radiation, causing them to adopt complex adaptation mechanisms. Phenotypic variation is the core manifestation of ecological evolution. Many have developed a series adaptive strategies through long-term natural selection evolution, enabling survive reproduce under harsh conditions. This article reviews techniques methods used in recent years study evolution high-altitude plants, including transplantation techniques, genomics, transcriptomics, proteomics, metabolomics their applications plant Transplantation technology focuses on phenotypic variation, which refers variations morphological, physiological, biochemical characteristics, exploring key roles utilization, photosynthesis optimization, stress-resistance protection. Multiple omics technologies, metabolomics, revealed genes, regulatory pathways, metabolic networks associated with at genetic molecular levels. At same time, limitations deficiencies current technologies were discussed. In addition, we propose future improvements existing advocate for integration different multiple levels mechanisms environments, thus providing insights research this field.
