Floods are expected to be one of the factors negatively affecting the social economy in the eastern region of China, where the frequency and magnitude of the effects are expected to increase in the coming years. Summers in Liaoning Province are often characterised by excessive rainfall due to the increased frequency of extreme weather events.
However, the susceptibility of cherry rootstock to fluctuations in soil moisture is widely recognised; in fact, waterlogging can cause the most susceptible plants to die in a single day. Therefore, in order to ensure cherry production even in these areas, certain methods such as effective cultivation practices (e.g., above-ground cultivation and special drainage systems), reoxygenation and activation of plant response mechanisms are necessary.

Examining the impact of gamma-aminobutyric acid (GABA) on the root tolerance of P. sachalinensis, a prevalent rootstock used in the area, was the subject of a study conducted by researchers from Henan and Liaoning Province. An increase in ascorbic acid and proline levels in the roots was observed following treatment with GABA, which mitigated the damage caused by waterlogging.
According to the results of this experiment, rootstock tolerance to conditions of prolonged soil saturation can be improved through the activation of enzymatic and non-enzymatic antioxidant defence mechanisms by the application of amino acids that can improve the plants' response to unfavourable conditions caused by water logging.

The tetraploid rootstock known as "Aijie" is characterised by its breakage in mid-March, blossoming in early April, and leaf shedding in November. The results of the tests indicated that “Aijie” induced higher growth rates compared to Gisela 6, three years post-planting.

Chilean Santina cherries have officially been classified as a low glycemic index (GI=39) food. This result opens new doors for nutrition-focused marketing and reinforces cherries' status as a healthy, smart fruit choice for consumers aiming for a balanced and low-GI diet.

China now absorbs 93% of Chile’s cherry exports, making them the country’s second most exported product after copper. Thanks to direct sea routes, improved logistics, and lower prices, Chile is boosting its position as a global leader in agri-food trade with China.
