It was studied the influence of nutrientsolutions on the diameter of flowers atLisianthus russellianus cultivars. Bell Fleurgenerated a difference of 0.53 cm, significantdifferences comparing with the control (tapwater). Echo Blue registered very significantdifferences that exceed the control with 2.17cm.Regarding the unilateral influence of nutrientsolutions on the number of flowers/stem atLisianthus russellianus, that Bell Fleurachieved a very significant positive differenceof 1.05 cm, which exceed the experimentcontrol. Mariachi Pink registered significantdifferences concerning the number offlowers/stem. The difference was 2.92 pieces,which exceed the control cultivar.Concerning the influence of nutrient solutionon the no. of petals/flowers at Lisianthusrussellianus cultivars, results show that neithersolution recorded favorable influence. CultivarsMariachi Pink and Echo Blue show verysignificant differences exceeding the controlcultivar with 8.33 pieces respectively 6.58pieces.In the case of the unilateral influence ofnutrient solution on the postharvest ofLisianthus russellianus, can conclude thatsolutions as Bell Fleur and Floralife assure along period of postharvest life from 12.78 daysto 11.89 days, comparing with the control.Echo Blue cultivar achieved significantdifference and this exceeds the control cultivarwith 4.92 days.REFERENCESArmitage A.M., 2001.
