Fig. 3. Seasonal changes in (a) maximum photochemical efficiency Fv/Fm, (b) total chlorophyll content, (c) chlorophyll a/b ratio and (d) soluble protein content measured between 1100 to 1200 h in cladophylls of ASP-69 (closed bar) and ASP-03 (open bar). Results are means of six replicates ± SE. Significant differences between ASP-69 and ASP-03 are indicated as *, P < 0.05; **, P < 0.01; ***, P < 0.001. Different letters within cultivars indicate statistically different values P < 0.05 as determined by Tukey's test.
