Induction of vitro-plants of two varieties of pineapple (Ananas comosus) L. Var. Cayenne smooth and MD2 grown in Côte d'Ivoire and assay of some biochemical compounds

Pineapple (Ananas comosus (L.) MERR) is the most widely consumed fruit in the world after the sweet banana. It's a fruit plant that plays a key role in the Ivorian economy. However, its cultivation is facing numerous problems due to the ageing of orchards and the abusive use of phytosanitary products, leading to a drop in fruit quality and yield. The revival of this sector is all the more important as it occupies a strategic position in the Côte d'Ivoire economy. Biotechnology seems to be a highly effective way of dealing with aging orchards. In this study, the influence of variety on in vitro shoot induction in two pineapple varieties (Smooth Cayenne and MD2) was tested to determine the mass production of healthy and high-performing shoots and then the biochemical compound content of the two pineapple varieties during shoot induction was tested. The results show that MD2 has the highest shoot induction capacity (87.93 shoots) and the highest phenol, flavonoid and leaf pigment content. Phenolic compounds and flavonoids are thought to be markers of shoot induction in pineapple. The MD2 variety is best suited to shoot induction.
