Abstract
The objective of this study is to show the real impact of methyl jasmonate and ethephon in combination on the production of phenolic compounds in cultivar R405-2000 of the cotton plant Gossypium hirsutum. As well, cotton plants were treated in the field by methyl jasmonate (MeJA), ethephon (ETH) and the association of methyl jasmonate and ethephon (MeJA + ETH). The effect of these treatments was appreciated thanks to a qualitative analysis of total phenols by High Performance Liquid Chromatography. The results showed that ethephon, the metabolic precursor of ethylene, has properties identical to those of MeJA. However, the treatment of cotton leaves with ethephon induces less phenolic compounds than MeJA. On the other hand, the co-treatment of the leaves with MeJA and ethephon leads to an induction of phenolic compounds, which accumulate in greater quantities in the plant the phenols synthesized are more important with an activation of the biosynthetic pathway of stilbenoids because trans-resveratrol and transpiceide, two compounds belonging to the group of stilbenoids were synthesized de novo by the joint application of MeJA and ethephon on cotton leaves when they could not be synthesized when these two elicitors are applied alone.

Summary
Cotton is a textile and protea-oleaginous plant to multiple use. [1]. It is a very important source of currency for the economy of several countries. The cotton plant is threatened by parasites and various diseases which reduce production, the quality of fibers and seeds [2]. Studies have shown that in front of aggression by pathogens, plants produce secondary metabolites, in particular phenolic compounds, to defend themselves [3]. Cotton produces a large number of phenolic compounds which are decisive in resistance to diseases [4]. Some plants remain susceptible to pathogens and the establishment of the disease, more by a slow defense response than by the absence of a defense mechanism [5 ; 6]. Studies have shown that MeJA and ethylene can act synergistically on certain defense genes, thereby leading to an increase in resistance to pathogens [7 ;8 ; 4 ; 9]. The object of this article is to show the qualitative impact of the co-traitment of methyl jasmonate and ethephon on the production of phenolic compounds in cotton sheets
