Echium plantagineum is a significant pasture weed in the Mediterranean climatic zone of several countries, including Australia. This invasive weed, introduced as an ornamental into Australia (where it is known as Paterson’s curse), quickly became established and is now a significant weed of agriculture. Although E. plantagineum is a well-established, highly competitive weed that thrives under disturbance and is tolerant of a wide variety of conditions, including varying soil moisture and drought, and some aspects of its ecology remain unknown. This study investigated germination response to temperature and light, pH, soil moisture, salinity, and pre-germination exposure of seed to heat and smoke. Temperature was found to be more influential on germination than light and the species is tolerant to a wide range of pH. However, available moisture may limit germination, as may elevated salinity. Management of this weed requires approaches that minimise soil seedbank input or prevent germination of soil seedbanks.

The effect of prechilling on the germination response to temperature was investigated by germinating prechilled (at 5 °C) and unchilled seeds of Betulapendula Roth (silver birch) at temperatures of 10, 15, 20, 25, and 30 °C in darkness. Unchilled and prechilled seeds produced 50% germination at temperatures of 26.7 and 15.3 °C, respectively. Two experiments were organized to study the effects of a range of prechilling temperatures (0–12 °C) on release of dormancy. The level of dormancy in the seeds was tested at 12 °C using 6- and 18-h photoperiods. The optimal prechilling temperatures were between 1.0 and 3.3 °C. As the prechilling temperature increased, the effect of prechilling decreased so that the upper effective limit was between 8.7 and 12.0 °C. The effect of prechilling time on dormancy release was studied in an experiment where seeds prechilled at 2.4, 5.5, and 12.4 °C for 6, 12, 21, and 42 days were germinated at 12 °C using 6- and 18-h photoperiods. The germination probability (in logit scale) was directly related to the logarithm of the number of prechilling days. In seeds prechilled at 2.4 °C the requirement for a long photoperiod for germination was removed in 21 days, whereas 42 days were needed in seeds prechilled at 5.5 °C.
