In the Min River Estuary wetland, Spartina alterniflora is an invasive plant that has outcompeted the local Phragmites australis. A study compared their photosynthetic abilities and found that Spartina alterniflora has a higher net photosynthetic rate, meaning it can use light energy more efficiently and produce more photosynthesis products. Additionally, Spartina alterniflora showed better adaptability to salty environments, likely due to its effective salt resistance mechanism.
