Abstract

fetched live from OpenAlex

Objective:To study the pollen viability,the stigma receptivity and storage character of Pseudostellaria heterophylla.Methods:The pollen viability was evaluated by the methods of in vitro pollen germination and pollen staining,the stigma receptivity was estimated by benzidine-H 2O 2 method,and the pollen viability in different storage conditions were detected.Results:In vitro pollen germination method was suitable for the determination of pollen germination of Pseudostellaria heterophylla,the optimal medium was 0.04% H 3BO 3+15% sucrose+11% PEG 4000,in which the pollen germination capacity reached to 92.44%;The stigma receptivity of Pseudostellaria heterophylla was higher when the pollen anther opening;The results showed that short-term pollen storage at-4 ℃was the most suitable while the long-term pollen storage was at-80 ℃.Conclusion:The optimum cross pollination times of Pseudostellaria heterophylla was 2 days after blooming and choose the pollen in anther opening.This study provides a foundation for the breeding and germplasm resources protection of Pseudostellaria heterophylla.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
