Effects of Cd~(2+) Stress on Plant Growth and Leaves Physiological Activity of Rice
Bibliographic record
Abstract
Using yangdao No.6 and wuyunjing No.7 as material,Carried potted experiment to study the effect of Cd2+ stress on rice plant growth and leaves physiological activity.The results showed that:(1)Cd2+ stress had a significant effect on tillering ability,plant height,accumulating amount of dry matters,composing factors of yield and physiological activity of leaves;(2)The sensitive stage to Cd2+ stress was the stage before flowering,and at flowering stage,Cd2+ stress had less effect.on tillering ability,plant height,accumulating amount of dry matters;(3) The most sensitive factor among composing factors of yield was grain number per panicle;(4)Cd2+ stress promoted electrical conductivity of leaves,MDA content,proline content and soluble protein content increasing and decreasing the rates of leaf photosynthesis at late tillering state.These reflected that Cd2+ stress injured the growth of rice plant,inhibited the differentiation of ears and decreased the yield,and proline content increasing under Cd2+ stress indicated that rice plant have certain tolerance for Cd2+ stress to some extent.

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.
