Abstract
The maintenance and improvement of the soil fertility are important aims in viticulture, taking also into account that the grapevines are usually cultivated in poor phyto-nutrient soils, and thus the efficient fertilization systems based on a maximum utilization of organic fertilizers are of present interest. The goal of this study is to explore the correlation between the type of soil organic fertilizer and the grapevine performances expressed in the accumulation of biochemical compounds which are involved in the plant growth and development. The study was conducted on two grapevine varieties for which the production aims at obtaining high quality red wines - Cabernet Sauvignon and Zweigelt – and which are grown in a plantation belonging to I.N.C.D.B.H. (the National Research and Development Institute for Biotechnologies in Horticulture) in Stefanesti-Arges. The undertaken studies have shown the positive influence of the soil organic fertilization upon the biosynthesis of the primary metabolites (soluble carbohydrates, chlorophyll and carotenoid pigments) and secondary metabolites (proteins, polyphenols, auxins) in the leaf, during the vegetation season.
