Effect of Quercetin on Mycorrhizal Synthesis between Tuberborchii and Arbutusunedo L. In Vitro Plants

Arbutus unedo L. is a Mediterranean species used for fruit production; it tolerant to drought and shows regeneration ability following forest fires. Mycorrhizal plants with Tuber borchii add resilience value. This study aims test the effect of quercetin on mycorrhizal synthesis between T. A. unedo. Two genotypes selected production hydric stress tolerance, were micropropagated synthesis, accomplished during ex vitro rooting in perlite, using lyophilized spores suspended culture media different levels (0–10 µM). Six months after inoculation, transferred pots maintained nursery. Ten 12 roots morphological examined molecularly characterized ITS1-5.8SITS2 rDNA region specific primers. Results showed that mycorrhizae establishment was dependent studied factors (genotype, level, medium) their interaction (genotype X medium). Quercetin up 2.0 µM favored plant growth, although superior 4 toxic effect. be an efficient factor inducing mycorrhiza thriving independent genotype.
