Determination of Viability of Japanese Larch Seeds using Hyperspectral Imaging = Determination of Viability of Japanese Larch Seeds using Hyperspectral Imaging

다국어 초록 (Multilingual Abstract)

Japanese larch (Larix kaempfen) is a deciduous needle-leaf conifer, which is valued for the production of strong, durable and naturally decay-resistant woods that have been used for construction of bridges, ships, buildings. Their ability to grow in a harsh cold environment, coupled with several values and uses, have stimulated interests in larch cultivation throughout. However, poor seed lot quality is the major hurdle for production of sufficient quantity of planting stocks. This study aims at the potential of Hyperspectral SWIR imaging to classify viable and non-viable seeds. In order to establish a model for viability determination, hyperspectral SWIR images for 200 seeds were collected with conventional germination test. A multivariate classification model with partial least square discriminant analysis (PLS-DA) was developed, and the accuracy was analyzed. The results show the good potential of hyperspectral imaging technique for the viability determination of larch seeds.
