Abstract

OBJECTIVE:

To improve salt resistance of Codonopsis pilosula seeds and seedlings under different salt-alkaline stress, the seed germination and physiological characteristics of seedlings were studied.

METHODS:

Several physiological indexes of Codonopsis pilosula under different salt-alkaline stress were measured, such as the germination vigor, germination rate, relative germination rate and recovery germination rate,as well as others indexes like the contents of chlorophyll, soluble protein, water and MDA and the activities of POD and SOD.

RESULTS:

The inhibitory effects of three salts on seed germination were Na2 CO3 > NaCl + Na2 CO3 > NaCl with an increased salt concentration. The contents of chlorophyll, soluble protein and water were found significant different (P < 0.05) from the negative control group, along with the decreased of these indexes. However, positive correlation existed between MDA content and salt treatment concentration. In addition, the change trend of SOD and POD activity were similar. They were increased firstly, and then decreased as the stress intensity extended.

CONCLUSION:

The seeds and seedlings under different salt-alkaline stress were inhibited, with different inhibitory extent as Na2CO3 > NaCl + Na2 CO3 > NaCl.
