Santosh Shrestha

During his studies, Santosh Shrestha investigated on prospects of three different non-destructive methods viz., near infrared (NIR) spectroscopy, hyperspectral imaging and multispectral imaging for seed quality assessment of tomato seeds. His results show that NIR spectroscopy can be used to classify the tomato seeds to their potential to germinate. Similarly, he demonstrated that hyperspectral imaging and multispectral imaging could be useful to identify the variety or genotype of a tomato seed. He concluded chemical compositional differences in the seeds in regards to seed viability or varietal identification is underlying principle behind the use of these technologies.

Based on the results, adoption of these investigated non-destructive and rapid methods could contribute in improving the seed quality status in the developing countries.

The PhD degree was completed at the Department of Agroecology, Science and Technology, Aarhus University.
