These data were acquired in a separate experiment from the biomass, in March 2013. Replication of the earlier biomass study was imperfect, as some plants became a little dry when watering was controlled to reduce moss growth. Sufficient plants grew strongly to measure ...

Data for Figure 3A-3F and Supplementary Figures 2, 3, and 6, including leaf number, biomass and leaf areas. Image data for leaf areas are included in a .ZIP archive.

Intact rosette is pictured, with plant number and genotype in handwritten labels, and ruler for scale. Then dissected leaves are organised in sequence of age, if necessary with small cuts to let them lie flat. Areas are then measured in image processing.

Data for Figs 3C, 3F and Supp 2 in Chew et al. PNAS 2014 Leaf number of the growing rosettes, from 4 to 37 days after sowing (DAS). Data and also results of FMv1 model simulations. Note that Fei-0 was previously tested by Mendez-Vigo et al, suggesting this line had a higher leaf appearance rate. We suggested that its larger final leaf number was more likely due to faster germination.

binary data file from "Hobo" environment multi-sensor + data logger, located next to the plants used in the experiment. Usually read in HOBOware software, free from Onsetcomp.com. Useful temperature record. Though light levels can usefully show changes they are not well calibrated.
