【Abstract】 Two groups of Aneurolepidium chinense seedlings were stressed by 300mmol·L -1 NaCl and 100mmol·L -1 Na 2CO 3,respectively and the effect of ABA,Ca 2+ and H 3PO 4 on relaxing their stress was studied.The results show that external Ca 2+ ,ABA and H 3PO 4 could obviously mitigat the inhibitory effect of NaCl and NaCO 3 on seedling growth. In the treatment of Na 2CO 3,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(NO 3) 2 was much better than that of CaCl 2,and of mingling CaCl 2 and ABA had a much better effect than CaCl 2 or ABA alone.更多还原
