NaCl-induced responses in giant duckweed ( Spirodela polyrhiza ) Tai-Sheng Cheng

摘要

ABSTRACT Salt accumulation leads to a decline in species richness in aquatic ecosystems. The effects of salt (NaCl) stress on plant growth and antioxidative responses in giant duckweed were investigated. NaCl significantly reduced photosynthetic pigment accumulation and inhibited plant growth. This inhibition in plant growth, may also provoke oxidative stress, enhancing malondialdehyde (MDA) and hydrogen peroxide (H2O2) contents in plant tissues. The antioxidative enzymatic analysis showed a si.
