Supplemental Information

Chilling and forcing functions from Prevéy et al (2018)

These functions were used to calculate the chilling and forcing units accumulated from 11/2/2017 through reproductive budburst for red alder cuttings, and trees at Webster Nursery..

Code used for analyses in manuscript. All code was run in the statistical program R (R Core Development Team 2017)

DOI: 10.7287/peerj.preprints.26489v1/supp-2

Raw data of dates of reproductive budburst for cuttings in all experimental treatments and trees at Webster Nursery

DOI: 10.7287/peerj.preprints.26489v1/supp-3

Raw data for hourly temperatures for all experimental treatments and Webster Nursery

Temperature data were collected with Hobo pendant temperature dataloggers (Onset Corporation, Contoocook, NH). One datalogger was placed alongside cuttings in each treatment, under a conical shade structure, and one datalogger was hung in a red alder tree under a conical shade structure at Webster nursery.
