TI  - Mitigation of Chilling Stress Effects on Eggplant Seedlings by Exogenous
Application of Melatonin
AB  - The purpose of this study was to explore the possibilities of improving chilling stress tolerance of
eggplant seedlings through exogenous melatonin (MEL) application. Eggplant (Hadrian F1)
seedlings were treated with various concentrations (0, 1, 5 or 25 μM) of MEL via soil drench after
which they were subjected to chilling stress at 5°C/10°C (night/day) for 3 days. Following stress
imposition, the efficacy of MEL applications on enhancing chilling stress tolerance was determined
by several physical and physiological measurements and biochemical analyses. The results
demonstrated that exogenous application of MEL alleviated the adverse effects of chilling stress in
eggplant seedlings. Among the MEL concentrations tested, 5 μM was determined as the most
effective concentration since antioxidant enzyme (CAT, POX and APOX) and photosynthetic
activities increased while visual and membrane damage decreased in 5 μM MEL-treated seedlings.
Also, these results are the first experimental evidence that exogenous application of MEL could
improve chilling stress tolerance in eggplant, but further detailed studies are necessary to better
understand the mechanism in acquiring chilling tolerance
