Project Title
- Plant phenomics and high-throughput phenotyping: accelerating rice functional genomics using multidisciplinary technologies
Key technologies in plant phenomics
- Since the first digital camera was invented by Eastman Kodak in 1975 (www.letsgodigital.org/en/16859/ce-hallof-fame), visible light imaging technology has been widely adopted in plant science due to its low cost and ease of maintenance. With a similar wavelength (400–700 nm) perception as the human eye, two-dimensional(2D) photography can be used to analyze shoot biomass
[18,19��], yield-related traits [20��], leaf morphology [23],panicle traits [24], and the system architecture traits of washed roots or roots grown in transparent media [25].
- Because of internal molecular movements, all objects emit characteristic infrared radiation [29]. Two popular infrared imaging devices can be used to screen radiation images: a near-infrared (NIR, wavelength of approximately 0.9–1.7 mm) imaging device and a far-infrared(Far-IR, wavelength of approximately 7.5–13.5 mm) imaging device. Healthy green plants reflect a large proportion of NIR light from 800 to 1400 nm, whereas the soil reflects little NIR light; moreover, soil and unhealthy plants reflect considerably more red wavelength light as compared with healthy plants. For these reasons, many studies have combined NIR imaging and visible imaging to detect vegetative indices. A Crop Phenology Recording System (CPRS) has been developed for monitoring rice growth. CPRS uses visible light imaging to derive the visible atmospherically resistant index and uses nearinfrared imaging (830 nm) to derive the night-time relative brightness index and then establishes the relationship between the camera-derived indices and
the agronomic traits [30].
