Analysis of the physical properties of spindle seeds for seed sorting operations

Abstract The relationships between the basic physical properties of seeds of selected spindle species were evaluated for the needs of seed sorting operations. Physical properties were measured in the seeds of five spindle species, and the presence of relationships between these attributes was determ...
