Abstract
The aim of the present study is to address the type of correlation that may exist between phenolic compounds and vine rhizogenetic potential by analyzing some phenolic compounds in the Carignan merithallus. Phenolic compounds were analyzed by HPLC in the young shoots (or merithallus) of Carignan vine (Vitis vinifera L.) and we established a correlation between the studied compounds and the rhizogenetic potential of shoots during the phases of bud dormancy and end of dormancy, taking into account the position effect on shoots. This work was carried out for the first time on this type of vine. Among the studied phenolic compounds, we observed a negative correlation between coumarin and rhizogenetic potential of Carignan vine. In contrast, positive correlations were found with naringin and syringic acid. Obtained results confirmed the fact that the action of phenolic compounds is complex and might be qualified as cofactors that interact with auxin on rhizogenesis.

The purpose of this work was to establish the correlation type that may exist between phenolic compounds and vine rhizogenetic potential by analyzing some phenolic compounds in the Carignan merithallus
HPLC Analysis Phenolic compounds were identified and quantified using RP-HPLC coupled to a UV-visible detector and equipped with a specific C18 column: Hypersil ODS (250 × 4.6 mm, 4 μm)
Summary
Polyphenols, a group of substances with a broad spectrum of physiological activities, are spread in plants used in traditional and modern medical systems. Phenolics have been shown to have a role in tissue browning, flavor, and color characteristics of the derived products [1]. An understanding of phenolic composition in fresh fruit and the factors that affect phenolic compounds are critical in the design of products and storage conditions [2]. Phenolic compounds are active biological molecules having one or more benzene rings with one or more hydroxyl functions [11]. Phenolic compounds contribute to development, cell multiplication, reproduction, differentiation, flowering, and lignification. Their content in plants depends on many genetic, physiological and environmental parameters [12]
