Abstract: (59 Views)
The purpose of this study was to evaluate how various morphological, phytochemical, and morphological traits of Mullein were affected by drought stress. A randomized completely blocks design with four treatments and four replications was used for this study. T1 (100% of field capacity), T2 (80% of field capacity), T3 (60% of field capacity), and T4 (40% of field capacity) were the stress treatments. Plant height, length of inflorescence, number of leaves per plant, flower diameter, flower yield, relative moisture content, proline, chlorophyll a and b, total phenol, flavonoid, and antioxidant activity were the characteristics that were examined. The analysis of variance results indicated that antioxidant activity and leaf number were not significantly affected by drought stress, but other variables were significantly affected (p <0.05). The findings demonstrated that drought stress resulted in a significant increase in proline and total phenol content and a significant decrease in morphological traits, flowers production, relative water content, and chlorophyll a and b. T1 and T4 had the greatest (9.99 mg Q/g DW) and lowest (91.9 mg Q/g DW) total flavonoid contents, respectively. Total phenol contents ranged from 28.1 (mg GAE/g DW) for T4 treatment to 27.47 (mg GAE/g DW) for T1 treatment.
