Abstract
Previous work with edible crops have showed the relations between plant water status, and substrate water status : matric potential, 
m, volumetric water content, 
v, and substrate hydraulic conductivity, Kunsat.
The results obtained suggest the usefulness of Kunsat as a criterion for watering substrates.
The aim of this experiment was to study the hypothesis mentioned above, on a carnation bag culture.
Two types of perlites (coarse and fine) and three criteria for watering related withm (-2, -5 and -10 KPa) measured with electrotensiometers were used.
The combined effects of watering regimes and substrates on short and long time plant water relations and productivity were analyzed.
The usefulness of Kunsat as a complementary criterion for watering carnations grown in substrates is discussed.
