The different growing conditions and in particular fertilization, affects the physiology, morphology and anatomy of the plants and provides the necessary information to compare their biological plasticity. The aim of the present study was to trace the effect of optimized nutrition in at organic cultivation of greenhouse lettuce using different formulations of organic fertilizers, on the anatomical structure of the leaves in order to increase plant resistance to the abiotic stress. The experimental production of seedlings was conducted at the base of Agricultural University - Plovdiv, Bulgaria. Four bio fertilizers were used in six variants of biological plant cultivation. Morpho-anatomical analyzes of the leaf blate, epidermis and stomata were performed using the methods of comparative anatomy. In all variants of lettuce with organic fertilization applied, a positive effect on the anatomical parameters of the leaves was observed, which was a prerequisite for increasing the biological resistance of the plants.
