摘要

In this study, we compared plant height, weight, soil TPH concentration, and soil DHA level after 18 weeks of </span><i><span style="font-family:Verdana;">Zennia</span></i><span style="font-family:Verdana;"> <i>hybrida</i> </span><span style="font-family:Verdana;">cultivation with four different concentrations of 5-Aminolevulinic acid (ALA)-based liquid fertilizer: 1500-fold, 5000-fold, and 8000-fold dilutions, along with a non-treatment control of diluted ALA. The plants of ALA-treated were significantly taller than the non-treatment control. The plants of ALA-treated plants were higher in shoot fresh weight, shoot dry weight, and root dry weight than the non-treatment control. The plot of ALA-based liquid fertilizer with the 5000-fold dilution was significantly highest in shoot fresh weight, shoot dry weight, and root dry weight. ALA-treated plants were lower in the soil Total Petroleum </span></span><span style="font-family:Verdana;">Hydrocarbon </span><span style="font-family:""><span style="font-family:Verdana;">(TPH) concentration than the non-treatment control. The plot of ALA-based liquid fertilizer with the 5000-fold was significantly lowest in the TPH concentration. In addition, ALA-treated plants were </span><span style="font-family:Verdana;">higher in the soil dehydrogenase activity (DHA) than the non-treatment control.

This study indicated that ALA-applied zinnia-grown oil-contaminated soil is more effective than not.
