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.

通过空中种子库的寄存，寄存促进了地黄的持续存在

摘要Seroting在空中种子库中产生，通过避免腐烂、捕食或在土壤种子库中致命发芽，使一些植物物种能够持久存在。尽管这一概念在林业中更为常见，但在杂草科学中却很少受到关注。平均而言，在春季，在衰老7-8个月后，以及随后从短命土壤种子库中出现的群体之后，锦葵[Basia scoparia（L.）A.J.Scott]在109个样本点的气生种子库中保留了2091颗种子（约18.5%的种子）。因此，在高应力干旱易发环境中，保持同时在空气和土壤种子库中异步招募曲霉菌可以代表一种适应性的赌注对冲策略。

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.
