Study on Seed Germination Characteristics of Pasthyrostachys juncea with Different Ploidy
Bibliographic record
Abstract
Compared with diploidy,the seedlings of Pasthyrostachys juncea with tetraploidy have stronger viability,higher nutrient contents and better tolerance of lower temperature,drought and other extremely environments.This experiment is about the germination characteristics of two varieties of Russian wildrye with diploidy and tetraploidy.We compare their germination indicators which include bud length,root length,ratio of bud and the changes of amylase activity and soluble sugar content.The results showed that,tetraploid seeds are significantly higher than diploid seeds in the terms of 1 000-grain weight,germination rate,the germination energy,index of germinated and vigor(p0.01).Doubled chromosome can promote the growth of seedlings and roots,and especially has a stronger effect on seedling growth.Tetraploid seed had stronger amylase activity,rapid glucose metabolism,therefore much more soluble sugar provided energy for the necessary germination.

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.
