Effect of Sand Priming on Aged Seed Vigor and Physiological Changes of Transgenic Insect Resistant Cotton
Bibliographic record
Abstract
Seeds of transgenic insect resistant cotton cultivars,CCRI 41and Z-905,together with their genetic background cultivars CCRI 23 as contrast,were used to investigate the effects of sand priming on changes of cotton seed vigor,field emergence and seedling growth characteristics after artificial aging treatment.The research showed that sand priming had a significant effect on artificial aged seed vigor and seedling growth of the three tested cotton cultivars.The results of biochemical analysis showed that the activities of superoxide dismutase(SOD) and peroxidase(POD) in cotyledons and roots of CCRI 41 and Z-905 cotton seedlings increased significantly,after they were treated by seed priming with sand,comparing with their corresponding control.CCRI 23 with priming treatment maintained higher SOD and POD activities in its roots than its unprimed control.Meanwhile,sand priming dramatically reduced malondialdehyde(MDA) accumulation in cotyledons of the three varieties.The experiment indicated that sand priming could enhance the aging tolerance of seedlings due to increasing the antioxidant enzyme activity and reducing the malondialdehyde(MDA) accumulating in the cotton seedlings,which suggested that sand priming may help to improve seedling establishment and enhance the ability of aging tolerance in cotton.The results showed that the transgenic insect resistant cotton Z-905 and CCRI 41 had a better priming effect than that of the contrast CCRI 23 which had a higher anti-aging ability.

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.
