Effect of Endomycorrhizae on the Growth of Curcuma longa L. and Ocimum basilicum L.

Abstract

The project evaluated the effect of an endomycorrhizae commercial product (Abonamos Micorrizas) of the genera Glomus spp., Entrophospora spp. y Scutellospora spp. on the growth of the aromatic plants tumeric (Curcuma longa L.) and basil (Ocimum basilicum L.). Four treatments were established for each species, six individual plants for each (obtained from vegetative seed) for a total of 30 plants for each experiment. The plants were grown in the Laboratory of Natural Resources greenhouse of EARTH University in a completely randomized block design. At the time of planting the plants were inoculated with 1 g, 2 g, 3 g or 4 g of the commercial product plus a control treatment without inoculum. Tumeric plants were evaluated weekly for four weeks for the variables width of the first leaf, first leaf length, height of the pseudostem, pseudostem diameter and at the end of four weeks, tumeric and basil were evaluated for the variables aerial weight, root weight, number of roots, root length and root diameter. There was a mycorrhizal colonization in both species; the tumeric, with an inoculum of 2 g per plant, had an increase in plant biomass (p<0,05) whereas the basil showed significant differences from the control with doses of 1 g and 2 g for the evaluated variables. Using endomycorrhizae on basil cuttings had a positive effect on the survival of the plants and a dose of 1 g per plant showed the highest survival rate.

Key words: basil, biomass, tumeric, endomycorrhizae, inoculum, vegetative reproduction.
