|a Plants in natural environments are exposed to complex and unpredictable stress factors, with multiple stresses such as heatwaves and droughts often co-occurring, a trend that is intensifying with global climate change. Reflectance spectroscopy, a valuable tool in plant stress research, measures spectral properties that are closely tied to plant health. However, most existing studies have primarily focused on using spectroscopy to assess single stress factors, with a significant lack of attention on combined stress. While several reviews have provided valuable insights into the impact of combined stress on plant molecular and physiological responses, no review has addressed the potential for spectroscopy technology to quantify responses and enhance plant resilience to combined stresses. This review addresses this critical knowledge gap by synthesizing existing findings on plant spectral responses to two common stress combinations: drought + nitrogen deficiency and drought + heat stress. The limited number of studies identified in this review underscores the need for further research; however, they also demonstrate that plant spectral responses to combined stresses are often unique compared to individual stresses. These results point to three potential pathways by which spectroscopy can be leveraged to enhance plant resilience under combined stress conditions: generating new hypotheses, facilitating the selection of broad-spectrum stress-tolerant genotypes, and improving stress detection to refine precision stress management practices. This review also suggests that spectral responses to combined stresses differ from individual stresses across spectral regions, plant species, scale of spectral sensing, and possibly other factors not yet considered here. To advance reflectance spectroscopy as a tool to disentangle the impacts of combined stress, future research should prioritize enhanced experimental designs, standardized data presentation protocols, integrated modeling, and sensor synergies. Ultimately, addressing the challenges posed by combined stress requires interdisciplinary collaboration among molecular biologists, pathologists, physiologists, agronomists, breeders, engineers, and modelers
