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 effect of Cr in maize plants. The present study aimed to investigate the impact of the exogenous application of trehalose in maize under Cr stress. The two varieties of maize (FH-1046 and FH-1453) were carried out with three levels of Cr (0mM, 0.3mM, and 0.5mM). Findings showed that significant variations were observed for growth and biochemical parameters in both maize varieties under Cr stress and control. A foliar application of trehalose (30mM) was applied to both varieties and observed the positive effect of trehalose on the growth of maize plants by reducing the damaging effect of Cr stress. Cr at 0.5mM concentration significantly reduced the growth-related parameters and photosynthetic pigments as compared to the concentration of Cr 0.3mM. Trehalose significantly improves growth and improves photosynthetic activities in both maize varieties. So, it is concluded that Cr stress has a damaging effect on the growth and biochemical characteristics of maize plant. Moreover, trehalose alleviates the damaging effect of Cr by enhancing the growth and physiology of plant that ultimately increase the yield of maize crop as well as other crops.
