Effect of Cd Stress on Growth and Accumulation of Cd in Different Chinese Cabbage Genotypes at Seedling Stage
Bibliographic record
Abstract
A hydroponic experiment was conducted to investigate differences in growth and cadmium(Cd) accumulation in 5 varieties of Chinese cabbage at the seedling stage under different concentrations of Cd stress.The results showed that fresh weight of all varieties decreased under different concentrations of Cd stress,and the fresh weight was significantly lower than that of the control.Moreover,inhibition rate of growth of Zhebai No.8 was the lowest(53.86%) at 50 μmol/L CdCl_2.High concentration of Cd stress in the short term could promote dry matter accumulation of Chinese cabbage shoot.There were significant differences in cadmium contents of Chinese cabbage shoots among different varieties under different concentrations of Cd stress,in which cadmium contents of cabbage shoots of Zhebai.No.8 was relative low(145.1 mg/kg DW,249.7 mg/kg DW).Chlorophyll content of all varieties of Chinese cabbage decreased under Cd stress,and chlorophyll a/b had different changes in different Cd concentrations.

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.
