The study looked at different types of barley plants to see how they handle salty conditions. They found that the plants' ability to handle salt is linked to the amount of salt in their leaves and how much water they lose through their pores. Plants that lose less water through their pores are better at handling salt. Having more pores on their leaves can help barley plants use water more efficiently and be more tolerant to salt. The number of pores on the leaves affects how much water the plants lose. Overall, increasing the number of pores on barley leaves and reducing water loss could help them grow better in salty conditions.
