A Method for the Quantitative Determination of Transpiration in Plants


1. In plant breeding and in physiological and ecological work, it is very necessary to have some accurate and practical method of measuring the transpiration of plants. 2. The potometer method does not give the normal transpiration rate of a plant, neither can it be depended upon to give a rate which is even comparative as between different plants. 3. By the method herein described the transpiration of a plant under known and constant conditions may be accurately measured. 4. It is possible by this method to demonstrate individual differences in the transpiration rates in different plants of the same species. 5. By the use of this apparatus, data may be secured to serve as a basis for plant selection and breeding.
