“…C . album has widely infested many agricultural soils, and it causes substantial interference with crop productivity (e.g., decreased yield and quality), thereby threatening food security broadly [ 7 , 8 ]. A primary reason for its flexible adaptation relies on higher seed germination potential under benign and adverse environmental conditions [ 22 ].…”

“…album exhibit more viable seeds germination and subsequent seedling emergence when seeds are at the soil surface after seed dispersal in the field [ 22 ]. Chamkhi [ 8 ] and Alshallash [ 26 ] indicated that light could be a prerequisite for germination of this species, which exhibited rare germination in darkness across all temperatures tested. The light environment of the seeds provides essential information that triggers dormancy termination and the subsequent germination of many weed seeds in the proper environmental situation [ 41 ].…”

“…The species is invasive in China and recognized as one of the most widespread and problematic weed species in the industrialization of cropping systems, including under conventional tillage coupled with intensive use of herbicides and nitrogen fertilizers [ 6 ]. It often emerges throughout the spring and summer, with the peak of germination occurring in early to mid-spring and rapidly infests agricultural fields [ 7 , 8 ]. While C .…”

“…For example, the dormancy of black C . album seeds can be alleviated either after storage for 330 d at room temperature [ 21 ] or after ripening at low temperatures in the dark moist conditions for 4 to 52 weeks [ 8 , 22 , 23 ]. High levels of endogenous nitrate can improve the germination response to ethylene or GA4+7 [ 24 ], and exposure of seeds to exogenous nitrate can promote germination [ 22 , 25 ].…”

Chenopodium album L. is a troublesome annual species in various cropping systems, and a sound knowledge of the ecological response of C. album germination to environmental factors would suggest suitable management strategies for inhibiting its spread. Preliminary laboratory-based research was conducted to investigate germination and emergence requirements of C. album under various environmental conditions (e.g., photoperiods, constant temperature, salinity, moisture, soil pH, burial depth, and oat crop residue). Results showed C. album seeds were found to be photoblastic, with only 13% germination in darkness. The maximum germination (94%) of C. album occurred at an optimal temperature of 25°C, and the depressive effect of other temperatures on germination was more severe at lower rather than higher temperatures. Seed germination was suitably tolerant of salinity and osmotic potential, with germination observed at 200 mM NaCl (37.0%) and -0.8 MPa (20%), respectively. Germination was relatively uniform (88–92%) at pH levels ranging from 4 to 10. The maximum germination of C. album was observed on the soil surface, with no or rare emergence of seeds at a burial depth of 2 cm or under 7000 kg ha-1 oat straw cover, respectively. Information provided by this study will help to develop more sustainable and effective integrated weed management strategies for the control of C. album, including (i) a shallow-tillage procedures to bury weed seeds in conventional-tillage systems and (ii) oat residue retention or coverage on the soil surface in no-tillage systems.
