| Zusammenfassung: | In an apparatus for measuring diffusive resistance of plant parts, such as leaves, in which the part is placed in a test cup and the rate of rise of humidity of dry air in the cup is measured electronically and converted to a displayed value, compensation is provided both for ambient temperature variation by means of a thermistor and for previously measured humidity leakage into the cup from the exterior surroundings to enable accurate compensated diffusive resistance values to be determined easily and quickly. |
