Responses of Physiological, Morphological and Anatomical Traits to Abiotic Stress in Woody Plants

Shan Li; Sen Lu; Jing Wang; et al. Forests 2023. doi:10.3390/f14091784

Other claims from this paper (10)

Observation Xylem hydraulic conductivity usually declines under abiotic stress.
Association The hydraulic decline is associated with stomatal regulation and aquaporin inhibition.
Observation Woody plants adjust root and leaf size and morphology to balance water uptake and loss.
Observation Abiotic stress alters anatomy toward denser stomata, narrower conduits and thicker cell walls.
Intervention effect Flooding induces adventitious roots and aeration tissues.
Intervention effect Low temperature induces tissue freezing.
Intervention effect Salt stress hinders ion absorption.
Intervention effect Heavy metals induce biological toxicity.
Observation Drought, flooding and heavy metals can occasionally promote woody plant growth.
Observation Combined stress effects on woody plant traits are not simply additive.

Other claims from this paper (9)

Observation Abiotic stress reduces xylem water transport.
Mechanism Woody plants adjust root and leaf dimensions and structure to balance water intake and evaporation.
Observation Abiotic stress is associated with denser leaf stomata, smaller conduits, and thicker cell walls.
Observation Flooding induces adventitious roots and aeration tissues.
Observation Low temperatures cause tissue freezing.
Observation Salt stress hinders ion absorption.
Observation Heavy metal exposure induces biological toxicity.
Observation Drought, floods, and heavy metals can periodically enhance woody plant growth.

Intervention effect Citric acid stimulation released about 50% more resin.
Intervention effect Ethrel yielded resin amounts similar to the traditional paste.
Intervention effect Salicylic acid yielded resin amounts similar to the traditional paste.
Intervention effect All stimulants reduced seedling growth.
Intervention effect Midday water potential did not differ significantly across stimulants.
Intervention effect Stomatal conductance did not differ significantly across stimulants.
Association Internal resin accumulation correlated strongly with total resin production.
Association Resin canal density correlated strongly with total resin production.
Intervention effect More acidic pastes tended to cause resin retention.
Mechanism The authors infer moderate acidity suffices to trigger resin biosynthesis and release.
Recommendation The authors propose citric acid as a safer alternative to conventional stimulants.
