Climate data for four sites from which Brassica tournefortii seeds were collected in 2009, from the estimated start of germination events (May) until the month of seed collection for Dalwallinu (October), Merredin (December), Morawa (November) and Perth (November). The shaded area indicates the monthly temperature range. The black columns are the total monthly rainfall. ‘Total rainfall’ = cumulative rainfall; ‘Rain days’ = number of days on which rainfall was recorded; ‘Rain events’ = number of days or consecutive days of rainfall, bounded by ≥1 d with zero rainfall. All data from Australian Government Bureau of Meteorology (2010).
