Effects of Abscisic Acid on Soluble Sugar Accumulation of Cyphomandra betacea Seedlings under Cadmium Stress

In this study, the effects of different concentrations (0, 1, 5, 10, and 20 μmol/L) of abscisic acid (ABA) on soluble sugar accumulation in Cyphomandra betacea seedlings under cadmium stress were studied. The results showed that spraying 10 and 20 μmol/L ABA could effectively increase the content of soluble sugar in roots, stems, leaves and aerial parts of C. betacea seedlings. Spraying 1 and 5 μmol/L ABA reduced the soluble sugar content in roots, stems, leaves and aerial parts of C. betacea seedlings. Therefore, the use of 20 μmol/L ABA can increase the accumulation of soluble sugar in C. betacea seedlings. (paper)
