Forage Plant Ecophysiology under Different Stress Conditions.

Forage production often occurs in fragile environments with low fertility and various limitations [...

Changes in morphological traits associated with waterlogging, salinity and saline waterlogging in .

Rising incidences of waterlogging and salinity, particularly in extensive livestock farming areas, pose increasing challenges to plant growth. This study investigated the morphological growth responses and tolerance of 39 Festuca arundinacea accessions to these stresses, with tolerance quantified by the relative growth rate under stress versus control conditions. Notably, more productive accessions under normal conditions also showed greater stress tolerance.

Shaking off the blow: plant adjustments during submergence and post-stress growth in forage species.

Flooding significantly hampers global forage production. In flood-prone regions, Lotus tenuis and Lotus corniculatus are common forage legumes, yet little is known about their responses to partial or complete submergence. To address this, we evaluated 10 Lotus accessions subjected to 11days of either partial or complete submergence, analysing growth traits related to tolerance and recovery after de-submergence.

High Recovery from Either Waterlogging or Drought Overrides Any Beneficial Acclimation of Facing a Subsequent Round of Stress.

Climate models predict that plants will face extreme fluctuations in water availability in future global change scenarios. Then, forage production will be more frequently subjected to the destabilizing pressure of sequentially occurring waterlogging and drought events. While the isolated effects of drought (D) and waterlogging (WL) are well characterized, little is known about the consequences when both stresses occur sequentially.

Eco-Physiological Traits Related to Recovery from Complete Submergence in the Model Legume .

Submergence is a severe form of stress for most plants. is a model legume with potential use in assisting breeding programs of closely related forage species. Twelve genotypes (10 recombinant inbred lines (RILs) and 2 parental accessions) with different constitutive shoot to root dry mass ratios (S:R) were subjected to 7 days of submergence in clear water and allowed to recover for two weeks post-submergence; a set of non-submerged plants served as controls.
