Abstract

Winter wheat [Trificum aestivum (L.) em Thell. CY. Stephens] seedling growth and development were observed for plants grown in a greenhouse in 1.65 × 10 ^‒4m³ or 3.40 × 10 ^‒3m³ of potting soil to determine the effect of restricted root development on plant growth with adequate water and minerals supplied. Plants grown in a smaller volume of soil were significantly reduced in size as measured by number of leaves and culms/plant, main stem height, and final dry weight/plant. These results suggest that confining roots to a small volume of rooting medium will in itself limit coordination of plant growth in an otherwise suitable environment.
