Potato Research Aims and scope Submit manuscript

Summary

Cellular membrane thermostability of leaf tissue, measured by both leaching and direct conductivity, was used as an index for evaluating potato (Solanum tuberosum L.) leaf tolerance to high temperature. Experiments with eight genotypes showed that maximum differences between cultivars in response to temperature occurred at 52.5°C. The wide variability among the genotypes suggested that this index could be used to screen potato foliage for tolerance to heat. The results agreed well with visual scoring after exposing potted plants to 52.5°C.
