X-ray densitometry to assess internal seed morphology and quality

Non-destructive procedures are desirable for a precise internal seed morphology assessment. In this research the efficiency of X-ray densitometry for internal seed morphology analysis and physical quality of squash, melon and watermelon was evaluated. Seeds were submitted to X-ray densitometry and a typical density profile for each seed was generated. Based on the detailed densitometry profiles it was possible indicate density values for specific seed regions of the seeds and identify causes of poor germination. X-ray densitometry was considered as a promising non-destructive procedure to evaluate internal seed morphology of squash, melon and watermelon and demonstrated a strong potential for further research in seed testing.
