Betaine Hydrochloride Treatment Affects Growth and Phenylpropanoid Accumulation in Tartary Buckwheat (<i>Fagopyrum tataricum</i>) Seedlings under Salt Stress
Betaine is one of the most competitive compounds that accumulate in different cellular compartments to adjust osmotic balance. Among the various stressors, salinity stress often leads to osmotic and ionic stress in plants, either increasing or decreasing certain secondary plant metabolites. In this...

| description | Betaine is one of the most competitive compounds that accumulate in different cellular compartments to adjust osmotic balance. Among the various stressors, salinity stress often leads to osmotic and ionic stress in plants, either increasing or decreasing certain secondary plant metabolites. In this study, different concentrations of NaCl, betaine, and combined NaCl and betaine were used in time-course experiments to investigate growth pattern variation and accumulation of phenylpropanoid compounds in buckwheat sprouts. A significant increase in growth was observed with the application of 0.1–1.0 mM betaine. Although overall, the total phenylpropanoid compounds were lower compared to the control, the sole application of 50 mM NaCl and 1.0 mM betaine especially enhanced the accumulation of some of these compounds in comparison to others. Betaine application at lower concentrations was found to enhance the growth of buckwheat sprouts slightly. The results of this study show that phenylpropanoid content did not increase significantly in any of the treatments. However, it was proven that the phenylpropanoid biosynthetic pathway is stimulated under abiotic stress, resulting in a higher accumulation of various phenylpropanoid compounds. This suggests that the level of accumulation of phenylpropanoid compounds due to abiotic stress may be species-dependent. |
