Arbuscular mycorrhizal inoculation enhances plant growth and changes root system morphology in micropropagated Annona cherimola Mill

Abstract

[EN] The effect of arbuscular mycorrhizal formation on plant development and root system morphogenesis in micropropagated Annona cherimola plants was investigated. A juvenile rootstock was used and already rooted in vitro plantlets were inoculated with arbuscular mycorrhizal propagules at the beginning of their acclimatization phase. Mycorrhization improved plant development (root, steam and leaves), but decreased the specific root length. Arbuscular mycorrhizal formation did not change the degree of branching nor the lateral root frequency for the adventitious roots, but significantly increased the intensity of branching of the first-order laterals. These results corroborate the role of arbuscular mycorrhizal symbiosis inducing beneficial changes in root system morphology and in the general developmental pattern in micropropagated plants. [FR] L'inoculation de mycorhizes arbusculaires augmente la croissance de la plante et change la morphologie du système racinaire d'Annona cherimola Mill micropropagés. L'effet de la formation de mycorhizes arbusculaires sur le développement de la plante et la morphogenèse du système racinaire d'Annona cherimola a été étudié. Un porte-greffe juvénile a été utilisé et des plantes déjà enracinées in vitro ont été inoculées avec des propagules de mycorhizes arbusculaires au début de la période d'acclimatation. La mycorhization améliore le développement de la plante (racines, tiges, feuilles) mais diminue la longueur spécifique des racines. La formation de mycorhizes arbusculaires ne change pas pour les racines adventives, ni le degré d'embranchement, ni la fréquence des racines latérales, mais augmente sensiblement l'intensité des branchements des racines de premier ordre. Ces résultats corroborent le rôle de la symbiose mycorhizienne dans l'induction de changements bénéfiques au niveau de la morphologie du système racinaire et en général du développement de plants micropropagés.
