Growth and Potassium Partitioning in Tomato1

Abstract

Solution and sand culture experiments were conducted with ‘Early Pak’, ‘VF 145’, and ‘UC 82’ tomatoes (Lycopersicon esculentum Mill.) to study the propensity for K stress shown by ‘VF 145’ plants. The measured parameters that may contribute to the expression of K stress in ‘VF 145’ are low root weight and K content, high shoot:root ratios, high fruit K content, and a low K efficiency ratio.
