However, none of the herbicide treatments involved in this study provided this level of control when applied at the six-leaf stage. In summary, B. pilosa germination has been clearly shown to be stimulated by light and thus its emergence was greatest from the soil surface. This suggests that infestation from this weed will remain as a problem in no-till conservation agriculture systems, the use of which is increasing now throughout the world. It is intended that information generated from this study be used to develop more effective integrated management programs for B. pilosa and similar weeds in commercial agricultural environments which are tending toward conservation approaches. © 2019, The Author(s).]]> Wed 07 Apr 2021 14:02:18 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:14148 Wed 07 Apr 2021 14:02:13 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:14115 Wed 07 Apr 2021 14:02:11 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:14054 80% germination in darkness for both populations at all tested temperature ranges. Germination significantly declined as salinity and osmotic stress increased for both populations, with seeds from the Tempy population were more affected by NaCl >100 mM than seeds from Werribee, but in neither population was there any observed effect of pH on germination (>80% germination in both populations at all tested pH ranges). For both populations, germination significantly decreased as burial depth increased however, the two populations differed with regard to response to burial depth treatment, whereby seeds from the Tempy population had higher emergence than those from Werribee at 0.5 cm burial depth. These results suggest that light-reducing management techniques such as mulching or use of crop residues will be unsuccessful for preventing germination of wild lettuce. By contrast, burial of seeds at a depth of at least 4 cm will significantly reduce their emergence.]]> Wed 07 Apr 2021 14:02:08 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:14053 Wed 07 Apr 2021 14:02:08 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:13551 Wed 07 Apr 2021 14:01:40 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:13376 Wed 07 Apr 2021 14:01:31 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:13360 Wed 07 Apr 2021 14:01:31 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:13099 Wed 07 Apr 2021 14:01:17 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:13092 Wed 07 Apr 2021 14:01:17 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:12060 Wed 07 Apr 2021 14:00:22 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11945 Wed 07 Apr 2021 13:57:14 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11290 Wed 07 Apr 2021 13:56:38 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:11028 73%) was observed in the range of pH 6.4 to 8 than the other tested pH levels. Heat shock had a significant effect on seed germination. Germination of seeds placed at 130 C for 5 min was completely inhibited for both dry and presoaked seeds. The results of this study will help to develop protocols for managing feather fingergrass, and to thus avoid its establishment as a troublesome weed in economically important cropping regions.]]> Wed 07 Apr 2021 13:56:21 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10786 Wed 07 Apr 2021 13:56:09 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:10771 80% at a depth of only 0.5 cm in soil. Water stress greatly reduced seed germination (45% germination at osmotic potentials below -0.2 MPa). Germination was completely inhibited at water potentials of -0.4 to -1.0 MPa. This species is moderately tolerant to salinity, with over 50% of seeds germinating at low levels of salinity (60 mM NaCl), and moderate germination (49%) occurring at 120 mM NaCl, it can germinate well in both alkaline (pH 10-83%) and acidic (pH 4-80%) conditions. The results of this study have contributed to our understanding of the germination and emergence of green galenia, and this will assist in developing tools and strategies for the long term management of this noxious weed in Victoria and other parts of Australia.

In the elevated CO2 condition, the GS biotype plants were >38% taller and produced >44%, >18%, and >21% more leaves, buds, and seeds, respectively, compared with the ambient CO2 concentration under both moisture regimes. The biomass also increased by 27% in comparison with the ambient CO2 concentration. For the GR biotype, plants at the elevated CO2 level, while they also grew 38% taller in comparison with the ambient CO2 concentration, the numbers of leaves, buds, and seeds and biomass were not affected by this increase in CO2. Results showed that there were minimal changes in response to glyphosate for GR and GS biotypes of S. oleraceus with or without moisture stress. Our study suggests that future climate change with elevated CO2 levels can affect the response of S. oleraceus to glyphosate, and such knowledge will be helpful for weed management in the future. © 2020 Weed Science Society of America.]]> Mon 25 Jul 2022 11:05:15 AEST ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:17002 Mon 19 Dec 2022 14:04:49 AEDT ]]> http://researchonline.federation.edu.au/vital/access/manager/Repository/vital:15012 Mon 12 Apr 2021 13:51:15 AEST ]]>
