Abstract
— The rooting of the apple rootstock M9 Jork was increased by addition of phloroglucinol (162 mg/l) during rooting in the light in presence of 2 mg/l IBA.Other phenols (catechol, chlorogenic acid, p-coumaric acid and querce- tin) did not show the same synergic effect.Phloroglucinol had no effect when added during the multiplication stage.GA 3 added during multiplication enhanced the rooting ability somewhat at a low concentration (1 mg/l), but was inhibi- tory at higher dosages.Sorbitol when used as carbon source during multiplication gave the best results in comparison with other sugars.Peroxidase activity was lower in the microcuttings rooted with the addition of phloroglucinol than in those grown in the presence of the other phenols or without phenols.Electrophoretic patterns of isoperoxidases did not show any particular changes due to the treatments. in vitro rooting / carbon source / peroxidase Résumé — Effets du phenol, de l'acide gibbérellique et des glucides sur l'enracinement du pommier porte- greffe M9 Jork.La capacité à l'enracinement du porte greffe M9 Jork du pommier a été augmentée par un traitement avec du phloroglucinol (162 mg/l) quand l'induction à l'enracinement des microboutures a été faite en présence de 2 mg/l de AIB et une photopériode de 16 h.D'autres composés phénoliques, catéchol, acide chlorogénique, acide pcoumarique et quercétine ne montrèrent pas les mêmes effets synergiques.Des résultats variables suivant la dose ont été obtenus avec l'utilisation de GA 3 alors que le sorbitol utilisé comme source de carbone donnait les meilleurs résultats.L'activité péroxidasique était inférieure dans les microbutures enracinées avec l'addition de phloroglucinol à celle des boutures mises en présence d'autres phénols ou sans phénols.Les spectres isopéroxydasiques ne montrèrent aucun changement dû aux différents traitements.enracinement in vitro / source de carbone / peroxydase
