Germplasm image analysis of Astragalus maritimus and A. verrucosus of Sardinia (subgen. Trimeniaeus, Fabaceae)

Abstract

The relationships between A. verrucosus Moris and A. maritimus Moris, exclusively endemics of Sardinia, are studied with a germplasm image analysis system. Morphometric and colorimetric features of the seeds and fruits of the two taxa have been studied and statistically elaborated to verify and confirm the validity of these species and to improve the performance of the correct classification of the image analysis system, previously elaborated to be a tool for taxonomic studies.
