Plant growth chamber facility

所有潜在用户的研究迫切需要更多的面积来种植在稳定和高度可重复的条件(光照、温度、湿度)下无虫害的植物。特别是在细胞生物学部门，获得这种质量的植物生长领域是一个主要的瓶颈。拟南芥、烟草、番茄和药用植物需要在无害虫、严格控制的环境中生长，以实现以下目的：遗传转化、表型特征、转录本、蛋白质和代谢物水平的分析、电生理学以及逆境反应和植物-病原菌相互作用的研究。申请的植物生长室设施的地面平面图和设备可以设计成满足所有用户当前和可预见的未来需求，因为受青睐的供应商提供客户指定的尺寸和许多设备选项。该供应商的总工程师已经建造了许多运行可靠的植物生长室设施，包括在2006/7年度为我部生化部门安装的一个。由于受青睐的供应商用德国零部件建造增长室设施，并分享设计细节，因此可以委托分包商进行维护和维修，以节省后续成本。选择受青睐的供应商开发的LED照明系统可以进一步降低维护成本，这种系统的能耗是传统系统的一半，寿命是传统系统的10倍。我们进行的广泛测试表明，这些LED系统支持植物生长，至少与传统照明系统一样。

Research of all prospective users urgently depends on additional area to grow plants pest-free under stable and highly reproducible conditions (illumination, temperature, humidity). Particularly in the Cell Biology Division, access to plant growth area of this quality is representing a major bottle-neck. Arabidopsis, tobacco, tomato and pharmaceutical plants need to be grown in a pest-free, tightly controlled environment for the following purposes: genetic transformation, phenotypic characterization, analysis of transcript, protein and metabolite levels, electrophysiology as well as investigation of stress responses and plant-pathogen interactions. Ground plan and equipment of the requested plant growth chamber facility could be designed to meet current and foreseeable future requirements of all users, as the favored supplier offers customer-specified dimensions and many equipment options. The chief-engineer of this supplier has already built numerous reliably running plant growth chamber facilities, including one installed in 2006/7 for the Biochemistry Division of our Department. Because the favored supplier builds growth chamber facilities from German parts and shares design details, maintenance and repair can be commissioned to subcontractors to save follow-up costs. Maintenance costs can be further reduced by opting for LED illumination systems developed by the favored supplier, which consume half the energy and have a 10x longer life time than traditional systems. Extensive test we have performed have shown that these LED systems support plant growth at least as well as conventional illumination systems.
