Menta (Mentha arvensis L.) micro and macropropagation

Abstract

This work aims to develop two mint (Mentha arvensis L.) seedling production methodologies through micropropagation and macropropagation cuttings. In micropropagation the auxins naphthalene acetic acid (NAA), indole butyric (IBA) and indole acetic acids (IAA) at 0.01, 0.1 and 1 mg L-1 were evaluated independently. Contamination of 8 % was recorded. The number of roots presented statistically significant differences amongst the treatments. A 1:8 rate of multiplication was reached. A 100 % of the explants survived along acclimation. In macropropagation NAA, IBA and Nafusaku, at 10, 25 and 50 mg L-1 respectively, were evaluated. A 100% rooting was scored in all treatments. In the substrate perlite: sand: earthworm compost (1:1:1), a root system with more than 6 roots larger than 1 cm in length and larger total biomass was achieved.
