ANOVA of Cerium Chloride on Morphology and Metamorphosis Development in Tadpoles of C. melanogaster

In this experiment, the effects of 0.004 mg·L-1, 0.02 0.1 and 0.5 mg·L-1 cerium chloride solutions on growth metamorphosis development tadpoles black spotted frog were investigated. The experimental results showed that solution at mg·L-1significantly reduced survival rate tadpoles, which was 6.67% 168h (7d) in treatment compared with 93.3% blank control (lake water). condition (body weight) (0.56 g) different from water) (The (mass) slowed down significantly early to (0.67g ± 0.05g); same time, we noticed concentration a dormant state growth, mass not beginning experiment. time high salt (31 5 days) greater than (26 3 days).
