Effects of methyl jasmonate and salicylic acid on the growth and stress resistance of Pyropia haitanensis
摘要
Abstract
To explore the effects of plant hormones on algal physiology and stress resistance, we compared the effects of different methyl jasmonate (MJ) and salicylic acid (SA) concentrationson the growth rate, phycobiliprotein content, soluble protein accumulation, proline content, and chlorophyll fluorescence parametersin Pyropia haitanensis.Results revealed that the growth rate of P. haitanensis in the 100 μmol/L SA treatment groups increased 1.57 folds compared with that in the untreated control group.MJ treatment had no significant effect on the algal growth. We demonstrated that treatment with 50 μmol/L MJ and 100 μmol/L SA could significantly improve the algal phycobiliprotein content and soluble protein accumulation. Compared with the untreated control, proline content increased by 2.67 and 1.75 folds at 48 h when treated with 50 μmol/L MJ and 100 μmol/L SA, respectively. While the treatment with 25~50 μmol/L MJ had no significant effect on Fv/Fm and Y(II), treatment with 100 μmol/L SA improved both the two chlorophyll fluorescence parameters of P. haitanensis. These results indicate that treatment with MJ and SA at appropriate dosages was beneficial to the growth, photosynthetic capacity, and stress resistance ability of P. haitanensis.关键词
