Growing Plants Without Soil for Experimental Use.
Blankendaal, M.; And Others
Much of the current research in experimental plant biology requires highly uniform plants. To achieve this, many plants are grown under conditions in which the environment is carefully manipulated. This pamphlet has been prepared, therefore, to present and describe growth procedures which will produce vigorous, healthy, uniform plant material in regulated environments for experimental purposes. The publication is intended for those with some knowledge of plants who want to grow one or more species for experimental purposes, for demonstrations in schools, or for science projects where limited facilities are available. Topics discussed include: (1) control of environment--greenhouses, growth chambers, and seed germinators, (2) factors for plant growth--light, temperature, relative humidity, growth media, and nutrition, (3) germination of seed--two methods, (4) transplanting, (5) culture techniques--containers, aeration, subirrigation, and nutrient solution, and (6) techniques for specific plants. An index to more than 50 plants mentioned in the text is also given. The techniques and equipment described are those used at the Metabolism and Radiation Research Laboratory, Fargo, North Dakota.
