Abstract

Porous nutrient agar was prepared under sterile conditions by drawing molten 3.5% (w/v) nutrient agar into a plastic syringe, allowing it to set, extruding it into a test tube and giving the tube a firm flick. Simple colorimetric tests showed that gaseous diffusion was substantially faster through 3.5% (w/v) porous agar than through the 1% (w/v) non-porous agar frequently used for growing plants under sterile conditions. Root systems ofTrifolium subterraneum grew 80–90% larger in porous than in non-porous agar.
