Strawberry plants when experiences autotoxicity in recycled hydroponics exudates benzoic acid as their potential allelochemical. Exogenous application of benzoic acid showed gradual inhibition of growth of strawberry plantlets with the increase in concentration. It also found that, strawberry root injury start from 25 μM/L benzoic acid in the nutrient solution. Roots showed black discoloration and lower activity after this concentration. Compared to control, roots from benzoic acid concentrations showed intense color during NBT and DAB test, which indicate that allelochemical/ benzoic acid created stress condition to strawberry roots. Enzymatic reactions also showed up-regulation of SOD, POD, CAT, and APX activity while showed down regulation of MDA, O2.- and H2O2 activity.

草莓植株在再生水栽条件下发生自毒时，会分泌苯甲酸作为其潜在的化感物质。随着苯甲酸浓度的增加，草莓试管苗的生长逐渐受到抑制。研究还发现，草莓根系损伤始于25 μM/L的苯甲酸营养液。在此浓度后，根显示黑色变色和较低的活性。与对照相比，苯甲酸浓度处理的草莓根系在NBT和DAB试验中表现出强烈的颜色，表明化感物质/苯甲酸对草莓根系产生了胁迫。酶促反应还表现出SOD、POD、CAT和APX活性的上调，而MDA、O2. H2 O2活性。
