Abstract
Taking into account the large number of people suffering from hepatobiliary disorders, we wished to analyze more thoroughly the plants with effect on these disorders. Thus, in this paper presents we present the biometric determination for the main morphological characteristics of plants and the results of biochemical determinations effectuated on artichoke, cultivated in the pedoclimatic conditions of the municipality Tecuci, county Galati, fro three consecutive years: 2006, 2007 and 2008. The biometric determinations were effectuated both in the field and in the lab, in the period of vegetative growth and in the blooming phase. The content in assimilating pigments was determined by spectrophotometry with computer rendering by measuring the absorbance, for wave lengths characteristic to pigments. We noticed that, during vegetation, the content in carotenoids increases. We also noticed that the ratio between chlorophylls increases due to the more rapid degradation of chlorophyll b as compared to chlorophyll a and decreases when the content in chlorophyll b increases.

Key words: pedoclimatic conditions, biometric and biochemical determinations, influence of pedoclimatic factors
