The heat wave in Germany in 2018 led to considerable yield losses in agriculture. Tomatoes are important crops in vegetable cultivation worldwide. Excessively high temperatures damage their fruit development. If the heat persists, the plants not only suffer from a lack of irrigation, but their metabolism is also considerably impaired. Prof. Dr. Jutta Ludwig-Müller, Professor of Plant Physiology at the TU Dresden, and her team are developing agricultural strategies to reduce such heat-related yield losses. In experiments, they found that this heat causes hormonal stress in tomato plants, which produce the best fruit yields at moderate temperatures. The team succeeded in demonstrating that the plant hormone auxin significantly decreases during the flowering and fruit development of tomatoes under heat. Treating the heat-infested plants with the plant hormone led to a significant improvement in fruit development.
