Abstract
摘要： 采用荧光显微技术, 对摩擦禾、薏苡花粉在玉米柱头上的萌发和生长过程进行了观察。摩擦禾花粉粒在玉米柱头上均能萌发, 花粉管在柱头中伸长并到达花柱基部, 且可将雄配子送入胚囊内, 玉米果穗顶端有受精结实痕迹, 说明摩擦禾与玉米的杂交障碍不是杂交不亲和, 而是胚囊不亲和或杂种衰亡。薏苡花粉粒在玉米柱头也能萌发, 花粉管能伸入花柱, 但玉米与薏苡杂交生殖隔离较摩擦禾严格, 杂交极其困难, 杂交障碍为胚囊不亲和或花柱不亲和。玉米与薏苡杂交时, 薏米花粉管能到达玉米花柱基部, 而川谷花粉管却在花柱中停止生长, 杂交障碍与薏苡种类有关。玉米与薏苡杂交的花粉管异常率高于玉米与摩擦禾杂交花粉管异常率, 反映了玉米与摩擦禾的亲缘关系较与薏苡近。

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.
