The researchers studied different types of Miscanthus plants to see which ones grow best in salty soil. They looked at the biomass yield (how much plant material is produced) and quality of the plants. They found that the hybrids (plants made by crossing different types of Miscanthus) grew better and had higher quality than the parent plants. Two hybrids, SL8 and SL15, were especially good for salty soil. This shows that mixing different types of Miscanthus plants can make them grow better in tough conditions.
