Abstract:
Trehalose is a non-reducing sugar, which mitigates the toxic effect of abiotic stresses such as salinity, drought, and heavy metal. Trehalose is used to mitigate the Cr toxicity in maize plants. The present study aimed to investigate the impact of the exogenous application of trehalose in maize seedlings under Cr stress. Two varieties of maize (FH-1046 and FH-1453) were grown with three levels of Cr (0mM, 0.3mM, and 0.5mM) and exogenously foliar application of trehalose. Findings of present investigation showed that significant reduction was observed for growth and biochemical parameters in both maize varieties under Cr stress. However, foliar application of trehalose (30mM) was significantly reduced the damaging effect of Cr stress. Cr at 0.5mM concentration significantly reduced the growth-related parameters, photosynthetic pigments and biochemical characteristics as compared to the Cr 0.3mM. Trehalose application significantly improves growth by enhancing the photosynthetic activities and biochemical attributes in both maize varieties. So based on the facts, it is concluded that Cr stress has a damaging effect on the growth and biochemical characteristics of maize seedlings. Moreover, trehalose alleviates the damaging effect of Cr by enhancing the growth and physiology of plant that ultimately increase the yield of maize crop and may be effect for other crops as well.
