Data for: Fridell et al. - Photoperiod does not affect thermal acclimation of shoot-scale gas exchange but is important for shoot development in cuttings of Norway spruce (Picea abies (L.) H. Karst)

https://doi.org/10.5878/pjgb-yy92
The data set contains measurement data collected during a factorial day length x warming experiment on Norway spruce (Picea abies (L.) H. Karst) cuttings of two geographical origins. The cuttings were exposed to combinations of long (20 hours of daylight) or short (14 hours of daylight) days and warm (25/20 °C day/night) and cool (15/10 °C day/night) growing conditions for three months in growth chambers. Collected data include gas exchange variables measured using a Li-Cor 6400 portable photosynthesis system for determination of light response curves and photosynthetic responses to differing intercellular CO2 concentrations (A-Ci curves). Needle properties including leaf mass per area and nitrogen content were determined. In addition, the height growth of the cuttings and the rate of bud development was observed under the different treatment conditions. The data set is divided into five files: 1) Definitions of the variables names and units used in the data files 2) Gas exchange data for generating light response curves 3) Gas exchange data for generating A-Ci curves 4) Needle property data, which also includes data on tree origin 5) Height growth and bud development data
