Weed Research. The identification of factors affecting seedling recruitment is therefore fundamental to understanding basic plant population processes (Annette and Katharina, 2010, Willenborg and Johnson, 2013). Though teachers could allow other variables to be tested, … Seeds germinated across a wide range of temperatures (5–35°C), with germination of over 90% at 15–20°C. 2000; 48: 212–216.
