摘要：

Of 12 different plant growth regulators (PGRs) tested,5-aminolevulinic acid (ALA) was found to improve the salttolerance of cotton seedlings. Cotton seedlings treated with ALAcould grow in soil containing levels as high as 1.5% (wt/wt)NaCl. The analyses of mineral compositions of plant parts revealed that the Naplus concentrations in the roots of the plantstreated with ALA were suppressed to low concentrations. Fromthese results, it can be presumed that the presence of ALA maycause a reduction of Naplus uptake.
