Effect Of Hydroculture Methods On Tomato Root Morphology And Anatomy, Lia Maclellan

Honors College

Three methods of hydroculture were compared for their effects on the root anatomy and morphology of tomato (Solanum lycopersicum cv. Defiant). A hydroponic deep water culture method, an ebb-flood system using expanded clay pellets as a solid medium and an aeroponic sub-mist system were compared, with a solid peat/perlite medium for control. The treatments were found to have significant effects on plant root and shoot length, as well as root and shoot biomass. Root morphology was visually distinct among treatments, and all methods of hydroculture were associated with a significant increase in vascular tissue in plant roots compared with the …
