Influence of colonization by arbuscular mycorrhizal fungi on three strawberry cultivars under salty conditions
Bibliographic record
Abstract
Plant adaptation to hyperosmotic environments is generally associated with reduced growth and ultimately yield loss, making farming difficult. The potential of mycorrhizal symbioses to alleviate salt stress has been documented and benefits to plant revealed to be specific and dependent to both plant cultivars and fungal strains. A factorial greenhouse experiment was performed to determine the effects of three arbuscular mycorrhizal fungi (AMF) species (Funneliformis caledonius, F. mosseae and Rhizophagus irregularis) on three ‘day-neutral’ strawberry (Fragaria × ananassa Duch.) cultivars (‘Albion’, ‘Charlotte’ and ‘Seascape’), and a mixture of R. irregularis and F. mosseae on ‘Seascape’, under four salt conditions (0–200 mM NaCl). The overall results showed that plant biomass decreased with increasing salinity. The cultivars responded differently to both AMF and salinity, and ‘Seascape’ was more tolerant to salinity than the other cultivars. AMF enhanced plant growth and improved salt tolerance by increasing the proportion of medium (0.5<ɸ≤1.5 mm) and coarse (ɸ>1.5 mm) diameter roots. The mixture of two AMF species increased root and shoot mass to a higher degree than each species alone at low salinity (0–50 mM) but reduced fruit quality. At higher levels (100–200 mM), R. irregularis alleviated salt stress and improved fruit quality to a higher degree than the other AMF species. Our results support the use of bio-inoculants in saline horticultural areas. Because cultivars respond differently to fungal inoculants, and inoculants prefer specific environmental conditions, fungal inoculants need to be screened on a cultivar- and condition-specific basis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
