Effects of Seawater Salinity and Temperature on Growth and Pigment Contents in Hypnea cervicornis J. Agardh (Gigartinales, Rhodophyta)

Figure 3

Salinity and temperature effects on photosynthetic activity of H. cervicornis cultured for 15 days in sterile seawater enriched with f1 mother liquid and compounded to different salinities, placed in different intelligent illumination incubators with regulated temperature and light intensity. The photosynthetic activities were measured once every five days, four times in all (containing initial value); finally the average value was obtained. Treatments with distinct asterisk indicate significant differences according to the two-way ANOVA (GraphPad Prism 5 Demo); *𝑃<0.05 and **𝑃<0.01.
