“…It is clear from our results that cold stratification had a significant effect on seed dormancy breakage. This is consistent with earlier reports of common weeds in which seed dormancy is broken by cold stratification, for example A. retroflexus (Kępczyński & Sznigir, ), C. album (Baskin & Baskin, ; Matsuo & Kubota, ), C. suecicum (Scholz) Murr. (Milberg & Andersson, ) and C. rubrum L. (Galinato & Van Der Valk, ).…”

“…A range of environmental factors, such as temperature, light and soil chemistry, have been reported to play a role in regulating seed dormancy release and germination in these species (Baskin & Baskin, ). For example, cold stratification could release seed dormancy of A. retroflexus (Kępczyński & Sznigir, ), C. album (Baskin & Baskin, ), C. hybridum (Hu et al ., ) and Setaria glauca (Amini et al ., ), depending on stratification duration (Kępczyński & Sznigir, ; Baskin & Baskin, ; Amini et al ., ) and seed sources (Amini et al ., ). However, no studies have reported the effects of soil moisture content during cold stratification on the dormancy status of these species.…”

Summary Although the effects of cold stratification on the release of physiological dormancy in seeds have been studied extensively, knowledge of the role of soil moisture content on seed dormancy release during cold stratification is limited. Our study determined seed dormancy characteristics and the effect of soil moisture content on seed dormancy breakage during cold stratification in the five common weed species Amaranthus retroflexus, Chenopodium album, Chenopodium hybridum, Plantago lanceolata and Setaria glauca. Seeds of all five species were dormant at the time of harvest and their germination response to light and temperature varied. Soil moisture content had a significant effect on seed dormancy release of all species except P. lanceolata. Germination percentage of A. retroflexus, C. album, C. hybridum increased and then decreased as soil moisture content increased, regardless of germination test temperature. The optimal soil moisture content and seed moisture content for dormancy breakage of A. retroflexus, C. album, C. hybridum were 8%, 12%, 8% and 22.0%, 37.7%, 25.7% respectively. Dry storage (after‐ripening) significantly increased germination of S. glauca. Moreover, increasing soil moisture content first slowed and then increased dormancy breakage in S. glauca. These results suggest that data on soil moisture content should be incorporated into models that predict weed seed dormancy breakage and timing of seedling emergence as well as those for weed management.

“…Dormancy of these seeds can be removed by means of burial in late autumn and winter (Egley 1989;Kępczyński and Sznigir 2013). Likewise, cold stratification may release dormancy in these seeds, however, less effectively than burial (Kępczyński and Sznigir 2013).…”

Amaranthus retroflexus seeds were dormant at 25°C in the darkness and in the light, and also at 35°C in the darkness. GA 3 and ethylene partially removed dormancy at 35°C in the darkness and at 25°C in the light. Dormancy was removed by 1-5 days of treatment with nitric oxide or cyanide. The effect of NO and HCN was inhibited by cPTIO, thus the effect of HCN was NO dependent. Dry storage for 16 weeks could partially release dormancy only at 35°C, but not at 25°C. Dry storage increased the response to light, GA 3 and ethylene. The response to GA 3 and ethylene at 25°C was enhanced with increasing storage temperature. GA 3 , ethylene and nitric oxide could substitute dry storage and stratification in partially dormant seeds.

Although seed dormancy is advantageous for annual plants in the wild, unsynchronized germination in the laboratory leads to increased error in measurements. Therefore, techniques to promote and synchronize germination are routinely used. Ultrasound is one of the newest methods for breaking dormancy in weed seeds. We have investigated whether ultrasonic waves can be used to break seed dormancy of common lambsquarters (Chenopodium album), a highly competitive annual weed that leads to significant reduction of yields of corn, soybeans, and sugar beets. Ultrasonic waves with frequency of 35 kH were applied for 0 (control), 5, 10, 15, and 30 min using a completely randomized design. The results showed that the use of ultrasound waves generally enhanced the traits under investigation in the treated samples compared with the control sample. The maximum enhancement of germination percentage (180%), seedling dry weight (78%), and seedling vigor index I (271%) and II (392%) was seen in the common lambsquarters samples treated with ultrasound for 15 min and seedling length (40%) at 30 min compared with the control samples. Radical lengths were not statistically different from controls under any treatment and plumule length only increased marginally. These changes are reflected in seedling vigor index I and II measurements. For some of these traits, increasing the length of ultrasound treatment to 30 min had negative effects. These results demonstrate that ultrasound technology can be used as a quick, and efficient nondestructive method to break seed dormancy in common lambsquarters.
