[Effects of Ca2+, ABA and H3PO4 on relaxing stress of Na2CO3 and NaCl].
Two groups of Aneurolepidium chinense seedlings were stressed by 300 mmol.L-1 NaCl and 100 mmol.L-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.
