Parameters assessed include the number of roots, shoot length (cm), leaf length (cm), leaf width (cm), root length (cm), root weight (g), shoot weight (g), leaf area (cm2), and root-to-shoot length ratio. Distinct lowercase letters (a–e) denote significant differences between treatment means. Units for each parameter are presented where applicable.
