- Abstract
In order to study the effects of salicylic acid on the growth and physiological performance of Ulva prolifera with different proliferative styles, we took U. prolifera from vegetative (VU) and spore proliferative cells (SU) as materials, and cultured them under different salicylic acid concentrations to investigate their growth rate, chlorophyll fluorescence, SOD and soluble protein content. The results showed that the growth of both VU and SU was promoted by low concentration of salicylic acid, especially for VU. Under 0.2 μg·mL-1 salicylic acid treatment, VU showed the highest relative growth rate of 21.0%, and the maximum photochemical efficiency (Fv/Fm) increased by 9.8% compared with SU. Additionally, salicylic acid affected the SOD activity significantly, and the enzyme activity of VU increased by 52.0% and 198.6% under 0.2 and 0.5 μg·mL-1 salicylic acid treatment, and that of SU increased by 54.1% and 38.0%, respectively. Salicylic acid also promoted the relative electron transfer rate (rETR), photosynthesis and protein content of both VU and SU. In conclusion, salicylic acid benefited the growth of two kinds of U. prolifera, especially for VU.
