Abstract

Two cultivars of the cucumber plant (Marketmore and Pepino de China) supplied

with two total N levels (14 and 7 mol m-3) and a N03-/NH/ ratio of 60/40 were grown

aeroponically in a glasshouse. In order to known the N efficacy differences between the

cultivars, several parameters were chosen, such as dry matter production; the ratio of

rootlshoot weight; NR activity; commercial yields; N03-, NH4+ and total N consumptions;

leaf and root concentrations. The results obtained displayed that Marketrnore produced

higher yields and lower vegetative weigth than Pepino de China, showing furthermore the

highest ratios offruit weight, N03-, NH/ and total N consumptions for the treatment with

7 mol m-3 of total N. The data obtained can be used for an adequate selection of cultivars

characterized by a high N efficacy even for low N amounts.
