摘要

为评估油菜（Brassica napus L.）根系结构特征，开发了一种半水培系统。在受控条件下，四个栽培品种在浸泡在半强度霍格兰溶液中的发芽纸卷中生长。7、14 和 21 天后，使用 WinRHIZO 软件分析了八个参数，包括总根长、总根表面积、平均根径、根尖数、主根总长、侧根总长、三级根总长和基部链长。结果表明，在半水培系统中生长 14 天是准确评估根系性状的最佳时间，因为既能观察到明显的差异，又能保持操作和扫描的简便性。

Optimizing the evaluation of root system architectural traits in Brassica napus

A semi-hydroponic system was developed to assess canola ( Brassica napus L.) root architectural traits. Four cultivars were grown under controlled conditions in germination paper rolls immersed in half-strength Hoagland’s solution. Eight parameters, including total root length, total root surface area, average root diameter, tip number, total primary root length, total lateral root length, total tertiary root length, and basal link length, were analyzed using the WinRHIZO software after 7, 14, and 21 days. The results suggested that 14 days in the semi-hydroponic system were optimal for accurate root trait assessment, as clear differences were observed while maintaining ease of handling and scanning.

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.
