Abstract
With the indoor water cultivation methods,this paper studied the effects of different concertration chromium on seeds germination,seedlings growth and Chlorophyll content of corn and cucumber,and compared their differences of tolerance to chromium.The results showed that germination energy,germination rate,stress rate,vigor index,bud length of seedlings,root length,weight of buds and roots,and chlorophyll content of corn and cucumber showed upward tendency in low concentrations of chromium,such as 0.5 mg/L,1 mg/L,5 mg/L.When chromium concentration was 10 mg/L,seeds germination rate of corn and cucumber decreased,seedling growth were inhibited,and the inhibition for root was obvious than that of buds.The poison on corn occurred since 5 mg/L,the activity index decreased slowly.But cucumber seeds were poisoned at 10 mg/L chromium,and the activity index decreased very quickly.This phenomenon showed that corn seed had stronger tolerance than cucumber seeds for chromium.The most promotion for corn seedlings early growth was 0.5 mg/L,and for cucumber seeds was 1 mg/L.Chlorophyll a and chlorophyll b content of corn and cucumber seedlings were increased in low chromium concentration.Chlorophyll content of corn and cucumber seedlings began to decrease at 20 mg/L,and chlorophyll a content decreased more faster than that of chlorophyll b.

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 it
