Interest in determining transpiration rate of cut anthuriums led to the development of a method employing the use of a hygrometer (a humidity sensor). Transpiration rates of cut flowers held under ambient (28 °C, rh 60-80%) and refrigerated storage conditions (18 and 13 °C, rh 80-90%) obtained by hygrometry were found to be similar to those obtained by the traditional, direct weighing method. These rates also declined logarithmically with storage time. Hygrometry can be successfully used to directly measure the quantity of water vapour released as a result of the transpiration process.
