Seedlings of Vallisneria natans were planted in waters with different turbidities of 30 NTU, 60 NTU and 90 NTU. Such turbidities were made by mud and sand particles below 100μm in diameter. Photosynthetic fluorescence characteristics were measured by a developed submersible pulse-amplitude modulated fluorometer, Diving-PAM.
