experiment because it shows and illustrates theresults spectacularly.Measurement of water consumption. Each vasewas labeled indicating the type of preservativesused and also used a scale on the vase, so wecould see the daily water consumption. In orderto avoid evaporation respectively to reduceevaporation to the minimum we wrapped thevases in a double layer of foil.Leaf temperature was recorded and measuredby the Phyto-monitoring system. The values ofthe administrated solutions tend to be close. Airtemperature ranges from 22,5 – to 24,4°C andleaf temperature gradually approach airtemperature values.RESULTS AND DISCUSSIONSThe laboratory was monitored by the Phytomonitoringsystem and GTH 2, so the humidityof the laboratory varied between 13,5 – 46%.Water temperature shows a close correlationwith the values recorded in air, ranging from 22– 22,75°C. Leaf temperature started beinglower than the air temperature (0,5°C), butgradually increased towards the end along thewilting process.Figure 3. Water consumption dynamicsWe noticed an increased water consumption inthe case of the Alstroemeria as well, especiallywith Chrysal and Bioplant. Chrysal consumed2470 ml of water in 19 days, Bioplant 2290ml. Oasis consumed 1820 ml, Control 950 mland Sapientia 770 ml of water.Figure 1. Ambient conditions during the experimentFigure 4. Daily water consumptionFigure 2. Leaf temperature335We filled the vases on the first day of theexperiment, so we did not register any waterconsumption on that day. Bioplant was in thefirst place with a daily water consumption of30-250, the highest daily intake was recordedon the fourth day (250 ml). It is followed by
