摘要: The demand for high-yield cultivars of Saccharina japonica in farming areas calls for a practical and simple method to select desired parental plants for seed breeding. In this study, we evaluated PSII photosynthetic performance by measuring chlorophyll fluorescence and the nutrient uptake rate in both the micro-gametophyte and macro-young-sporophyte in five native strains (S1, S2, S3, S4 and S5) of S. japonica with different morphological characteristics. We found significant differences in PSII photosynthetic parameters and nitrate uptake rates between the strains studied in both gametophytes and young sporophytes. Female gametophytes of all strains presented larger cell sizes than males (P < 0.05). Among all tested strains, S2 presented the largest cell sizes and highest levels of PSII photosynthetic parameters and nutrient uptake rates in female gametophytes and young sporophytes. In open sea cultivation, S2 presented the greatest width and largest fresh weight values but the lowest thickness among all strains studied. Correlation analysis further indicated that the algal fresh weight showed strong positive relationships with cell size (R-2 > 0.747), the PSII photosynthetic parameters of female gametophytes (R-2 > 0.689) and the nitrate uptake rate of young sporophytes (R-2 = 0.640). These findings are considered promising for the future seed breeding of renewable, high-yield strains.
