Description

Dataset comprising of morphological features of Poa annua specimens from different populations, that were grown in common garden type of experiment in four different simulations (2 soil types and 2 climate types in a cross-design)

Data was prepared and used for publication "Are certain populations of invasive Poa annua better suited to invading Antarctica? A common garden comparison of populations from four continents" by Rudak A, Galera H and Wódkiewicz M. 2025.

Table "All measurments common garden" is main raw data file that includes all measuments that were done as a part of the experiment. Plants were grown for 4 months in four different variants

Variants:

  • Ident_pop - There are nine different populations (8 populations from seeds collected in 2015 and one population from Antarctica from seeds collected in 2010)
  • Soil - there are two different soil types used: sA - Antarctic soil which is kind of a gravel, nutrient low soil, and sO - Optimal soil for the species - garden soil was used for this
  • Climate - there are two climate simulations cA - Antarctic climate and cO optimal climate

Measured traits:

  • height - height of aboveground part of the plant (in cm)
  • dry_above_biomass - weight of dried aboveground biomass (in g)
  • biomass_allo - Is a biomass allocation ratio between dry aboveground and dried belowground biomass of the plant
  • plant_arch - is a ratio of height of the plant to largest chord of ellipsoid being an approximation of plant's shape from above view - it was measured using photography analyzed in ImageJ software.
  • shoots - number of all shoots of the plant
  • flower_day - first day of observed flowering counting from germination
