Seerey, N., Shirtliffe, S. J. and Hucl, P. 2011. Seeds from unthreshed wheat (Triticum aestivum L.) spikes have reduced field emergence compared with threshed seed regardless of cultivar. Can. J. Plant Sci. 91: 583-585. Five wheat cultivars were evaluated for their ability to emerge as volunteers from cereal spikes and threshed seed. Emergence monitoring of two sites found differences between timing and total volunteer emergence varying with cultivar, and shed seed form. Seeds from threshed seeds had greater emergence than those from unthreshed spikes. Because of these differences, future studies should utilize both threshed and un-threshed wheat spikes to determine seedbank persistence.
