Abstract
Abstract Serotiny results in aerial seedbanks that enable persistence of some plant species by evading decay, predation, or lethal germination in the soil seedbank. Although more common in forestry, this concept has received little focus in weed science. On average, kochia [Bassia scoparia (L.) A.J. Scott] retained 2091 seeds plant−1 (∼18.5% of seeds) in aerial seedbanks among 109 sample sites in spring, 7–8 months after senescence and following subsequent cohort emergence from the short-lived soil seedbank. Therefore, asynchronous seedling recruitment of kochia persisting in simultaneous aerial and soil seedbanks could represent an adaptive bet-hedging strategy for successful establishment in high-stress drought-prone environments.
期刊介绍：
Published since 1957, the Canadian Journal of Plant Science is a bimonthly journal that contains new research on all aspects of plant science relevant to continental climate agriculture, including plant production and management (grain, forage, industrial, and alternative crops), horticulture (fruit, vegetable, ornamental, greenhouse, and alternative crops), and pest management (entomology, plant pathology, and weed science). Cross-disciplinary research in the application of technology, plant breeding, genetics, physiology, biotechnology, microbiology, soil management, economics, meteorology, post-harvest biology, and plant production systems is also published. Research that makes a significant contribution to the advancement of knowledge of crop, horticulture, and weed sciences (e.g., drought or stress resistance), but not directly applicable to the environmental regions of Canadian agriculture, may also be considered. The Journal also publishes reviews, letters to the editor, the abstracts of technical papers presented at the meetings of the sponsoring societies, and occasionally conference proceedings.
