Data Table: Barton_Drought_tolerance_greenhouse.csv Description: Data from greenhouse experiment testing seedling drought tolerance in Metrosideros polymorpha. Column headings and description: ID Seedling experimental identification number. BLOCK Experimental block, due to variation in germination timing. POPULATION Source of seeds, collected on Oahu Island. DROUGHT Experimental water treatment – control (watered every other day to 100% field capacity) and drought (watered every other day to 80% field capacity). FATE Harvested after 8 week drought treatment, or subjected to terminal drought with no water until the seedling died. DEAD Binary mortality (1 = dead; 0 = alive). HEIGHT Seedling height at harvest (cm). SHOOT Dry shoot biomass at harvest (g). ROOT Dry root biomass at harvest (g). LONGEVITY Number of days in terminal drought with no water before dying. TERMINAL_GWC Soil gravimetric water content (% field capacity) at the time of mortality in terminal drought.
