Overview

Research reveals the effects of spent coffee grounds on root growth in Allium cepa, suggesting optimal ratios to balance growth and cytotoxicity.

Key Points

  • The 40:60 mixture of spent coffee grounds and sand resulted in the most significant root growth.
  • Increasing levels of spent coffee grounds reduced the mitotic index, indicating potential cytotoxic effects.
  • Various chromosomal abnormalities were noted, including micronuclei and fragmented chromosomes, linked to increased spent coffee grounds.
  • Balancing the mixture of spent coffee grounds is crucial to maximizing plant growth while minimizing cytotoxic risks.
