Developmental and Anatomical Studies on the Root of Platycodon grandiflorum A.DC
Bibliographic record
Abstract
The development and the structures of the annual and the perennial tap roots of Platycodon grandiflorum were studied with the paraffin section and the semi-thin section.The results showed that the development of P.grandiflorumroot could be divided into four stages:promeristem,primary meristem,primary growth and secondary growth.The promeristem consists of three groups of initial cells;the primary meristem is composed of calyptrogens,primordial epidermis,periblem and plerome.The primary structure includes epidermis,cortex and stele.Parenchyma cells in cortex are dominant.The primary xylem is diarch. The secondary growth depends on activities of the vascular cambium and the cork cambium.The secondary structure includes periderm and secondary vascular tissue from the outside to the inside.Parenchyma cells are prominent in the secondary vascular tissue,and only small amount of vascular elements are scattered in them.The perennial roots have the similar structure to the annual one,but there are some differences in the length and the diameter of the tap root,the thickness of periderm and the area ratio between the xylem and the phloem.

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.
