Abstract

Abstract Hulless barley is a relatively new crop in eastern Canada. Best cultural practices must be developed for hulless barley to achieve its maximum yield potential. A study was carried out to identify the optimum seeding rates for hulless barley in eastern Canada. Six barley lines consisting of two-row and six-row covered and hulless varieties (AAC Azimuth, AAC Starbuck, CDC Ascent, AAC Bloomfield, AAC Ling, and CH2720-1) were seeded in six different seeding rates (250, 350, 450, 550, 650, and 750seedsm−2) in a factorial experiment with four replications at seven sites across eastern Canada. The results showed that the optimum seeding rate for covered barley was 250–350 seeds m−2, but those for hulless barley higher yield potentials were achieved at seeding rate from 450 to 550 seeds m−2. Two-row varieties were higher yielding and had higher protein concentration than six-row varieties. The results of this study show that there is potential for further development of high-yielding two-row cultivars for eastern Canada.

加拿大东部无壳大麦生产的最佳播种率

摘要:无壳大麦是加拿大东部一种较新的作物。必须为无壳大麦制定最佳栽培措施，以实现其最大产量潜力。在加拿大东部进行了一项研究，以确定无壳大麦的最佳播种率。在加拿大东部的七个地点进行了四次重复的因子试验，包括六行和六行覆盖和无壳大麦品种(AAC Azimuth, AAC Starbuck, CDC Ascent, AAC Bloomfield, AAC Ling和CH2720-1)，以六种不同的播种率(250,350,450,550,650和750种子率- 2)播种。结果表明，有盖大麦的最佳播量为250 ~ 350粒m−2，而无壳大麦的最佳播量为450 ~ 550粒m−2。二行品种产量较高，蛋白质浓度高于六行品种。本研究结果表明，在加拿大东部有进一步开发高产二行品种的潜力。

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.
