A comprehensive evaluation of salt resistance in three clove varieties by the fast fluorescence transient parameters
Bibliographic record
Abstract
Syringa oblata,S.oblata var.alba and S.reticular var.mandshurica were used as test materials to investigate physiological reactions of photosystem Ⅱ in leaves under NaCl stress using the fast fluorescence transients techniques.And a comprehensive appraisal of photosystem Ⅱ functions on the salt-tolerance was estimated in clove varieties.The results showed that the salt damage phenotypic characteristics and salt tolerance threshold values were basically the same as the trend of changes in chlorophyll fluorescence parameters in leaves of three clove.Along with the increasing of salt concentration,photosystem Ⅱ functions of three clove varieties were decreased,storage capacity PSⅡ electronic receptors were reduced,and electrons from Q A to Q B were inhibited.The inhibitions leaded to a reduction on electron transport from PS Ⅱ to PS Ⅰ,and the photosynthetic performance index on energy absorption basis(PI ABS) was significantly inhibited.φD o and DI o/RC in leaves of three clove varieties showed an increasing trend.That was to say,the excitation energy could be reduced by increasing the ratio of heat dissipation in leaves of three clove varieties under salt stress,and the leaf salt-tolerance could be improved.However,the exorbitant ratio of heat dissipation also reduced the energy ratio of electron transport(φE o and ET o/RC were decreased).There were significant or highly significant correlations among different chlorophyll fluorescence parameters in leaves of three clove varieties.The subordinative fuzzy function was used to evaluate comprehensively salt tolerance,results showed that the ordination of salt-tolerance in photosystem Ⅱ functions from high to low was as follow: S.oblata var.alba S.reticular var.mandshurica Syringa oblata.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
