Comparison on the Photosynthesis of Seedlings of Prunus serotina and Prunus serrulata
Bibliographic record
Abstract
With LI-6400 portable photosynthesis systems,the net photosynthetic rate(Pn),stomatal conductance(Gs)and intercellular CO2 concentration(Ci) under natural full light conditions were compared for Prunus serrulata from Guangshan County,Henan Province,P.serotina from Pennsylvania and Ontario.The results showed that:(1)P.serrulata had the maximum daily average amount of Pn,Gs,and Ci,which were 6.381μmol·m-2·s-1,0.200 mol·m-2·s-1,and 251.7 μmol·mol-1 respectively,and the average amounts of seedlings of Pennsylvania provenances were the medium,they were 5.550 μmol·m-2·s-1,0.151 mol·m-2·s-1,and 234.7 μmol·mol-1 respectively,and the average amounts of seedlings of Ontario provenance were the least,they were 4.952 μmol·m-2·s-1,0.134 mol·m-2·s-1,and 230.1 μmol·mol-1 respectively.(2) Pn,Gs and Ci had significantly differences among these species.(3)The daily variation of Pn was similar,there was only one peak of Pn in a day,but the Pn of plants of Pennsylvania provenance reached the peak earlier than that of the other two kinds of seedlings.The daily variation of Ci was similar,too.Ci decreased gradually from morning to the minimum in the afternoon and increased a little later,but the Ci of plants of Pennsylvania provenance fell the minimum earlier than that of the other two kinds of seedlings.The daily variation of Gs was similar,too.

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.
