中文摘要：

观赏园艺产业的发展，需要观赏植物品种的不断创新，包括品质的提高和种类的多样化。而品种的创新一方面依赖对植物生长发育过程的理解，另一方面需要新的生物技术的创新与应用。伴随着生命科学的快速发展，新的生物技术也不断涌现，为观赏植物新品种的培育提供了新的方法与手段。本文从细胞工程，分子标记及基因工程三方面，论述了现代生物技术在观赏植物中的应用。其中重点介绍了基因工程在观赏植物性状改良方面的应用，包括形态改良，生物及非生物胁迫抗性的提高，以及采后寿命的延长。最后，对一些可能应用于观赏植物并促进其发展的生物技术进行了展望。

英文摘要：

In this review, recent development and future prospects of biotechnologies application on ornamental horticulture in the world are presented. To bloom the floriculture industry, breeding of new cultivars with improved ornamental and agronomic traits are required, relying on total understandings of principles during specific developmental progresses and application of new biotechnologies. At present, new biotechnologies come out every day, providing breeders with new ideas and methods on breeding of new cultivars. Here, we summarized the application of biotechnology on ornamental horticulture in the fields of cellular engineering, molecular markers, and gene modification. The gene modification in specific traits of ornamental plants was emphasized on, including morphology modification, biotic or abiotic stress resistance improvement, and postharvest life elongation. Finally, some prospects for potential biotechnologies application in future horticultural research and breeding were explored.
