Propagation of Twelve Alaska Native Plants by Summer Stem Cuttings
Bibliographic record
Abstract
Abstract Twelve Alaska native plants were propagated from softwood and semi-hardwood stem cuttings collected from late June through August. Cuttings of new growth were treated with 0.3% indole-3-butyric acid powder and propagated in horticultural grade perlite and vermiculite (1:1 by vol) under intermittent mist with bottom heat [26C (79F)] in a greenhouse with a minimum night temperature of 15C (59F). After 6 weeks, cuttings were harvested and evaluated for rooting percentage and root quantity. Four species rooted poorly (< 25%) regardless of collection date: Siberian alder ( Alnus viridis ssp. fruticosa ), silverberry ( Elaeagnus commutata ), Bebb willow ( Salix bebbiana ) and shrub birch ( Betula glandulosa ). Best rooting (> 80%) occurred June 20 for: Beauverd spiraea ( Spiraea stevenii ), sweetgale ( Myrica gale ), and thinleaf alder ( Alnus incana ssp. tenuifolia ). Peak rooting for dwarf birch ( Betula nana ), feltleaf willow ( Salix alaxensis ), balsam poplar ( Populus balsamifera ), Labrador tea ( Ledum groenlandicum ) and littletree willow ( Salix arbusculoides ) was early to mid July. During peak rooting times, all successful species developed adequate root quantities for survival following transplanting.

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.
