Recent advances in plant biotechnology hold great potential for the ornamental horticulture industry. In addition to conventional methods, breeders can now introduce genetic variation into ornamentals by the application of recombinant DNA technology. This technology is particularly useful for effecting changes in phenotypic expression encoded by single genes such as corolla and foliage color and texture, stem length, scent, temporal regulation of flowering, vase life of cut flowers and resistance to stressful environments. In part, the commercial success of this technology will depend on developing reliable methods of transformation of ornamentals and on the stability of the introduced or altered genes. In addition, new and improved strategies of in vitro culture have been commercially implemented for the propagation and breeding of a wide variety of ornamental crops and will undoubtedly play a major role in the screening and propagation of chimeric plants developed by recombinant DNA technology.
植物生物技术的最新进展为观赏园艺产业带来了巨大潜力。除了传统方法外，育种者现在可以通过应用重组DNA技术将遗传变异引入观赏植物中。这项技术对于实现由单基因编码的表型表达变化特别有用，如花冠和叶片的颜色及质地、茎的长度、气味、开花的时间调控、切花的瓶插寿命以及对恶劣环境的抗性。这项技术的商业成功部分将取决于开发可靠的观赏植物转化方法以及所导入或改变基因的稳定性。此外，新的和改进的体外培养策略已在商业上用于多种观赏作物的繁殖和育种，并且无疑将在通过重组DNA技术培育的嵌合体植物的筛选和繁殖中发挥重要作用。
