Abstract

Plant performance depends mainly on the size and characteristics of photosynthetically active organs which are controlled by growing conditions and techniques.
In this context, in a factorial experiment, we studied the changes in some traits of eggplant leaves in the greenhouse in relation to: two thermal conditions, two radiative levels, and two nitrogen concentrations in nutrient solution.
The effects were evaluated by means of parameters concerned with leaf area, specific leaf area (SLA), chlorophyll content, stomatal density and lenght and leaf expansion rate (LER).

All the factors studied significantly affected leaf traits; moreover, within each climatic-nutritive condition, daily leaf expansion was related to the thermal conditions but not to radiation level.
