抽象。本研究以甘蓝型油菜（Brassica napus L.）评价了种质的发芽速度，这是植物生命周期中的关键特征。加入分为三类，快速（F），中，慢（S），9个F类（7%）和12个S类（9%）发芽加入鉴定和验证重复培养皿和盆栽实验。虽然F类品种的发芽和出苗速度明显快于S类品种，但幼苗生长参数差异不大。根据发芽速度和幼苗特性，鉴定出4份高早期活力和4份低早期活力的材料。种子萌发速度不受种子重量的影响，赤霉素和脱落酸不能简单地控制种子萌发，但10%烟水显著延缓种子萌发。这些具有不同早期活力的材料可用于研究油菜种子萌发和幼苗发育的遗传和分子机制，并可用于选育上级油菜品种。
Abstract. In this study, 137 canola (Brassica napus L.) accessions were evaluated for germination speed, which is a critical character in the plant life cycle. The accessions were grouped into three categories, fast (F), medium, and slow (S), with nine category F (7%) and 12 category S (9%) germination accessions identified and validated in repeated Petri dish and pot experiments. Although accessions in category F showed significantly faster germination and emergence than those in category S, seedling growth parameters did not differ greatly. Based on germination speed and seedling characteristics, four accessions with high early vigour and four with low early vigour were identified. Seed germination speed was not affected by seed weight and was not simply controlled by gibberellic acid and abscisic acid, but 10% smoke water significantly delayed seed germination. The identified accessions with contrasting early vigour can be used to study the genetic and molecular mechanism of seed germination and seedling development and to breed superior canola cultivars.
