Effect of NaCl treatment on the growth and physiological characteristics of different rice varieties

The effect of NaCl stress on the growth and physiological characteristics of different rice varieties were studied by using the seedlings of four rice varieties (Wu-shan-feng-zhan, Hua-hang-you-zhan, Yuan-er-you, Gu-you) as materials and determining the root length, fresh height, chlorophyll and malondialdehyde (MDA) content of the different rice seedlings after treatment with 150 mmol/L NaCl. The results showed that the plant height and root growth of different rice varieties was inhibited to a certain extent. The fresh weight and free water contained in the body were decreased. The chlorophyll content was lowered and MDA content were increased after treated with 150 mmol/L NaCl.
