Abstract: Two groups of Aneurolepidium chinense seedlings were stressed by 300mmol稬-1 NaCl and 100mmol稬-1 Na2CO3,respectively and the effect of ABA,Ca2+ and H3PO4 on relaxing their stress was studied.The results show that external Ca2+,ABA and H3PO4 could obviously mitigat the inhibitory effect of NaCl and NaCO3 on seedling growth. In the treatment of Na2CO3,praying it on leaves had a better effect than root irrigating,while in the treatment of NaCl,there was no significant difference.The effect of Ca(NO3)2 was much better than that of CaCl2,and of mingling CaCl2 and ABA had a much better effect than CaCl2 or ABA alone.
