Abstract Tomato ( Lycopersicon esculentum L. ‘San Marzano’) was grown in the greenhouse under normal conditions. After pollination of flowers in the first truss, plants were transferred to growth chambers with either 95% or 55% RH, light and dark temperatures of 18° and 15°C, respectively, and a 16:8 hr, (light:dark) cycle. Blossom-end rot symptoms developed at the distal-end on the young green fruit within 15–16 days at 95% RH. Plant tissues from plants grown at high RH had lower Ca concentrations than comparative tissues of the low RH plants and exhibited increased growth compared to the low RH regime plants. The K content was affected indirectly by the high RH in most of the tested tissues.
