Influence of Light,Temperature and Salinity on Seed Germination of Flaveria bidentis(Compositae),a New Exotic Plant
Bibliographic record
Abstract
Flaveria bidentis,an annual weed of Flaveria(Compositae),had been newly discovered in China.It might be a potential invasive plant in that of its very strong reproductive and survival abilities.Morphology and surface character of the seed were measured,and seed germination characteristics of this exotic species were examined from temperature,light,salinity to seed soaking aspects.The results showed that:the seed of F.bidentis were adapted well to high temperature and germinated rapidly at 35℃.Its germination percentage,germination index and vigor index were increased with the temperature rose.The germination percentage was affected little by light,while germination peak was delayed,and germination and vigor indexes of the seed were reduced with the prolonged light time.Salinity stress had significant effect on seed germination of F.bidentis:the germination percentage and peak decreased gradually with the increasing of NaCl concentration,while the germination and vigor indexes of the seed were higher than those of the control under 0.01 mol/L and 0.05 mol/L NaCl stress.Lower NaCl stress promoted the elongation of the radicle.Seed soaking also had notable impact on seed germination.In all,it was suggested that,the extremely high germinability and preference to salinity of the seeds of Flaveria bidentis could be closely related with its strong invasiveness.

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.
