Seed Dormancy and Germination of Endangered Plant Monimopetalum chinense
Bibliographic record
Abstract
Monimopetalum chinense Rehd,is the specific species in a single genus of China.It was listed as one of national proteceted plants at the second category in Chian because of its extremely low ability of regeneration in natural population.Several physiological indexes like the weight per 1 000-seed,content of moisture,the rate of water absorption and seed vigor were measured.The germination rate were determined under different treatments of stratification,sulphuric acid treatment and the combination of presoaking the seeds with GA3.The result showed that the 1 000-seed weight and average water content of the seeds were(4.504 8±0.055 8)g,13.18%±1.84%,resp.The rate of water absorption was 29.95%±1.58%,the seed vigor was 94.25%±0.017 1%,but the germination of seed was 0.Stratification time had no significant effect on germination percentage(GP),the highest GP was only 2.67%±1.53%.The treatment of soaking seed 20 min under 50% H2SO4,the GP was 18.00%±3.46%.The treatment of seed soaked 24 hours under 250 mg/kg,5 000 mg/kg,1 000 mg/kg of GA3,and 75 days of stratification,the GP were 72.67%±7.02%,68.00%±3.46,64.00%±5.29%,resp,but the GP of ck was 1.67%±1.15%.The results of this study illustrated the dormancy of M.chinense seeds could be breaken effectively.The mechanical and permeability barrier of seed coat had a negative effect on germination to a certain extent,seed dormancy of M.chinense was might be due to the inhibitory substances in the seed.The presoaking seed with GA3 was one of the best way to break dormancy.

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.
