Abstract
Factors affecting the uptake and distribution of calcium (Ca) by detached tomato (Lycopersicon esculentum Mill.) fruit were investigated in seven cultivars with different susceptibilities to blossom-end rot (BER), a physiological disorder caused by Ca deficiency. Plants were grown with different levels of salinity in the root zone or under shade to induce BER. In addition, fruit grown at different salinities were treated with CME, an inhibitor of auxin transport to alter IAA movement. The basipetal movement of indole-3-acetic acid (IAA) out of detached fruit (i.e. IAA efflux) was determined concurrently with 45Ca uptake to assess the possible involvement of IAA in Ca import or the incidence of BER. High salinity in the root zone during fruit development decreased both the uptake and distribution of 45Ca to the blossom-end of the detached fruit. Shading and the application of CME reduced 45 Ca uptake to a lesser extent. IAA efflux, however, was not consistently reduced by these treatments. Neither the uptake and transport of 45Ca within, nor the efflux of IAA from, detached fruit was related to the cultivar susceptibility to BER. The proposed role of IAA on the uptake and distribution of Ca by tomato fruit is assessed.
