Abstract
Drought is one of the major abiotic stresses that affect plant growth and
reduce agricultural productivity. Use of algal extract as a biostimulant is gaining
increased attention from researchers. This study aimed to investigate the potential
of
Ulva prolifera extract (UE) as a biostimulant when enzymatically extracted
under conditions of water deficit. UE treatments (0.02%, 0.06%, and 0.1%) significantly improved the shoot length, root length, and dry weight of roots after
120 h of drought stress relative to that in treatment with the negative control.
An increase in catalase (CAT) and peroxidase (POD) activity was also observed
that resulted in improved antioxidant capacity. Application of 0.1% UE reduced
the malondialdehyde (MDA) content by 30.06% compared with that in the negative control. In addition, the soluble sugar and protein content in wheat treated
with 0.1% UE was increased by 23.10% and 93.51%, respectively, resulting in
adjustment of the osmotic pressure. Results suggest that UE could significantly
enhance the drought tolerance of wheat. This study provides a basis for increasing
the value of UE as a biostimulant.
