The seedlings of Vallisneria natans were also restrained in the control where underwater light intensity was more than 43.3% of natural light intensity, but the seedlings grew well in the water at turbidity of 30NTU where underwater light intensity was more than 7.1%.
在对照水体中,水下的光强为水面光强的43.3%以上,苦草幼苗也受到抑制;而在水下光强≥7.1%的30NTU水体中,苦草幼苗有较高的光能利用率,幼苗生长较好。

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.
用粒径小于100μm的泥沙分别配置浊度为30、60和90NTU的浑浊水体,将苦草幼苗种植于上述水体中,测定幼苗的叶片长和叶片数,并利用水下饱和脉冲荧光仪测定幼苗的光合荧光特性,研究在不同浊度水体中水下光强对苦草幼苗生长的影响。
