A new scientific paper, “Tomato Cultivar and Rootstock Evaluation Under Mg Deficiency: Growth, Mg Uptake, and Leaf Gas Exchange”, has been published, highlighting the importance of magnesium (Mg) – an element often overlooked in modern agriculture. The research was conducted as part of the InToMag project, under the supervision of Dr. Branimir Urlić, analyzing how different tomato cultivars and rootstocks respond to magnesium deficiency, with a focus on plant growth, Mg uptake, and leaf gas exchange 🌱. Part of the analyses that contributed to the conclusions was carried out thanks to the instrument procured through the INOMED-2I project.

The results showed that differences among genotypes were visible already in the early stages of development, which can help in the faster identification of more resilient plants. Most plants grown under low Mg conditions had higher biomass, while magnesium concentrations in leaves and stems were higher under optimal Mg supply. Significant differences were also observed in total Mg content between cultivars, rootstocks, and grafted combinations.

These findings suggest that the selection of appropriate rootstock–scion combinations can be an important tool in breeding programs 🌍. However, further research is needed to assess their impact on long-term cultivation.
