Background and objective: The present research study aimed to investigate the optimum substrate volumetric watercontent (VWC) needed for Farfugium japonicum (L.) Kitam. to maintain its performance in the indoor garden.
Methods: The threshold levels of substrate VWC were evaluated as 0.1, 0.2, 0.3 or 0.4 m3·m-3 using an automatedirrigation system with capacitance soil moisture sensors and datalogger. Plant growth and physiological responses weremeasured and analyzed at 10 weeks after treatment. Plant growth was investigated by measuring survival rate, plantheight, leaf length, leaf width, leaf number, root length, fresh and dry weight of shoot and root. Physiological responseswere observed by analyzing antioxidant enzymes (SOD, POD) and antioxidants (MDA, proline), maximum quantum yield(Fv/Fm) and total chlorophyll contents.
Results: The results of drought tolerance measurement by the treatment group showed that the overall growth was thehighest in the 0.3 and 0.4 m3·m-3 treatment plot and the lowest in the 0.1 m3·m-3 treatment plot. Under the droughtstressedcondition of the 0.2 m3·m-3 treatment, growth was not as efficient as the 0.3 and 0.4 m3·m-3 treatments dueto the relatively higher moisture content, but there was no statistical difference between the 0.3 and 0.4 m3·m-3treatments in the maximum quantum yield (Fv/Fm) and also total chlorophyll content. Furthermore, for antioxidantactivities, SOD, POD, and MDA showed high values, but no statistical differences were found among treatments exceptfor the 0.1 m3·m-3 treatment, which was under severe drought stress in terms of proline.
Conclusion: Overall, the results indicate that Farfugium japonicum (L.) Kitam., has a tolerance to drought, and for managingindoor gardens the adequate soil moisture content for the growth is at least 0.2 m3·m-3 assuming the use of identicalsubstrate in this experiment.
