• To explore the use of leaf color as an indicator of plant chlorophyll and nitrogen status.

Main Methods:

• Utilized high-throughput imaging techniques to monitor plant growth.
• Analyzed spectral reflectance data to assess plant physiological status.
• Correlated leaf color with chlorophyll and nitrogen content.

Main Results:

• High-throughput imaging successfully monitored plant growth responses to different nutrient levels.
• Leaf color variations were indicative of changes in chlorophyll and nitrogen concentrations.
• Spectral reflectance provided quantitative insights into plant nutrient status.

Conclusions:

• High-throughput imaging offers a powerful, noninvasive tool for plant science research.
