The effect of method and duration of storage on life ability of St. John's wort (Hypericum androsaemum) seed
Bibliographic record
Abstract
Results of eight year research (2000-2007) of the quality of St. John's Wort seed relating to age of seed and type of packaging used for seed storage are presented in this paper. Seed was produced and treated additionally in 2000 prior to packaging of raw sees a sample was taken and placed on germination 4 x 100 seeds. Germination ability was considerably lower compared to seed investigated after one and several years of storage. Treated and packaged seed was stored in adequate storage in five types of packaging (wood, metal, natron, glass and jute). In subsequent years (2001-2007), samples were taken from each packaging type and placed on germination, 4 x 100 seeds. The best germination ability maintained up to 4 years (over 50%) was established in seed stored in natron packaging. After six years of storage this seed had germination ability of over 20%. The fastest diminishing of germination ability was established in seed stored in metal packaging (after 2 years it was bellow 40%, and after 4 years bellow 10%). Seed stored in wooden, glass and jute packaging maintained the germination ability up to 50% in first three years, after which the germination ability decreased rapidly. Seed stored in metal packaging lost germination ability fully after five years of storage (0%), and seed stored in glass packaging after six years, whereas seed stored in remaining three types of packaging demonstrated certain percentage of germination even after seven years of storage (mainly seed from natron packaging 6%). .

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.
