Daylilies are a versatile group of plants grown primarily as ornamentals in North America with great diversity in flower size, colour, and other characteristics. Despite the large degree of diversity available, few cultivars are commercially available and are not necessarily selected based on their suitability to Canadian growing conditions or even their floral characteristics. A major bottle neck in developing new cultivars for the mass market is the slow rate of plant multiplication of many promising cultivars. For example, while some cultivars reproduce quickly with a multiplication rate of 25:1 per season, others may only produce one new shoot per year. As a result, propagation rate limits the commercial feasibility of some desirable cultivars and it generally takes 10-20 years to move from the enthusiast market to commercial scale. The objective of this project is to test a variety of propagation strategies to increase the multiplication rate of daylilies to overcome this bottleneck, thereby reducing the time to market and enabling commercial production of some elite lines that multiply slowly using conventional means. These strategies will include root/leaf cuttings, application of growth regulators to induce multiple shoots, induction of proliferations on flower stocks, and the application of advanced cell culture techniques. As a result, Ontario daylily breeders/grower will be able to bring superior cultivars adapted to Ontario growing conditions quicker and cheaper, ultimately increasing consumer selection.

黄花菜是一种多功能的植物，主要在北美作为观赏植物种植，花的大小，颜色和其他特征都有很大的多样性。尽管有很大程度的多样性，但很少有品种是商业上可获得的，不一定是根据它们对加拿大生长条件的适合性，甚至是它们的花的特征来选择的。在为大众市场开发新品种方面的主要瓶颈是许多有前途的品种的植物繁殖速度缓慢。例如，虽然一些品种繁殖迅速，每个季节的繁殖率为25：1，但其他品种每年只能产生一个新的枝条。因此，繁殖速度限制了一些理想栽培品种的商业可行性，并且通常需要10-20年才能从爱好者市场转移到商业规模。该项目的目的是测试各种繁殖策略，以提高黄花菜的繁殖率，克服这一瓶颈，从而缩短上市时间，并使一些使用传统手段繁殖缓慢的精英品系能够商业化生产。这些策略将包括根/叶扦插，应用生长调节剂诱导多芽，诱导花卉砧木增殖，以及应用先进的细胞培养技术。因此，安大略黄花菜育种者/种植者将能够更快、更便宜地带来适应安大略生长条件的上级品种，最终增加消费者的选择。
