Other claims from this paper (12)
- Intervention effect ABA-sprayed barley plants under drought kept higher water content than untreated stressed plants.
- Intervention effect ABA-treated barley plants had the lowest rate of lipid peroxidation (MDA) under drought.
- Intervention effect ABA-treated barley plants lowered the rate of PSII primary acceptor reduction (1 – qP) under drought.
- Intervention effect ABA-treated barley plants increased the yield of regulated energy dissipation (NPQ) under drought.
- Intervention effect ABA-treated barley plants had higher accumulation of the PGRL1 protein under drought.
- Intervention effect ABA-treated barley plants kept photochemical efficiency and PSII electron transport at a similar level to well-watered plants under drought.
- Intervention effect Putrescine-sprayed barley showed a significantly less pronounced response under drought.
- Intervention effect Combined drought and H2O2 application increased 1 – qP and the quantum yield of non-regulated energy dissipation in PSII (ΦNO) in barley.
- Intervention effect Combined drought and H2O2 application reduced the accumulation of Rubisco activase (RCA) in barley.
- Intervention effect ABA foliar application restricted the risk of oxidative damage under drought in barley.
