Comparative analysis of physiological responses to environmental stress in Hedysarum scoparium and Caragana korshinskii seedlings due to roots exposure.

ABSTRACT: Hedysarum scoparium and Caragana korshinskii seedlings were used as the test materials to carry out the roots exposure stress model test. By comparing the physiological growth indexes in the leaves of the tested plants, the stress resistance ability was evaluated. The results showed (1) root exposure resulted in excessive oxygen free radicals, which resulted in membrane lipid peroxidation and increased MDA content in two plants. The increase of MDA content in H. scoparium was greater than that in C. korshinskii. (2) H. scoparium mainly regulate their own adaptation to the stress by regulating carotenoids. C. korshinskii adjusts itself to adapt to the stress by regulating chlorophyll. (3) H. scoparium resist this stress mainly by regulating t
