Portable handheld near infrared spectrometers for plant tissue analysis
Low-cost portable handheld near infrared spectrometers offer accurate, non-destructive analysis of plant tissue constituents in the field, aiding rapid assessment and breeding efforts.
Overview
Portable handheld near infrared spectrometers present a breakthrough in the realm of plant tissue analysis by offering a non-destructive, on-site testing solution. These devices have demonstrated comparable accuracy to traditional, more expensive desktop spectrometers, making them a viable option for rapid assessment of plant nutrients, energy content, fiber, alkaloids, and sugars in various crops, including forages, tobacco, and sugarcane. Their capability to determine foliar nutrient levels in fresh teak seedlings highlights their versatility and utility in both field and greenhouse settings.
