Abstract:Restriction of tomato roots by growth in small containers stronglysuppressed transport of 45Ca2+ ions to new leaves and apices.Water transport, expressed on a leaf area basis, was marginallyreduced by root restriction, an indication that calcium transportwas more severely limited than water transport.
