This is study evidences photosynthetic activity in Thalassia testudinum seeds.
Seed photosynthetic descriptors were calculated: (higher α, lower P. max, Ek, and Ec).
Seed photosynthesis is highly efficient and makes it well adapted to colonize habitats with reduced light availability.
Taking the Chl a/b ratio into account, the T. testudinum seed can be considered as a “Shade plant”.
The T. testudinum seed photo-adapt capability is very relevant in terms of possible settlement places where sink, characterized by different irradiance intensities.
