Influencia de la sombra y de las micorrizas sobre el crecimiento de plantas de lulo (Solanum quitoense Lam.)

The lulo plant (Solanum quitoense) native to Andean forests grows under partial shade in association with native mycorrhizae. In commercial cultivation lulo is often planted in full sun, which leads to plant stress. In order to evaluate the growth of lulo plants inoculated with mycorrhizae, under pa...

Description
Summary:The lulo plant (Solanum quitoense) native to Andean forests grows under partial shade in association with native mycorrhizae. In commercial cultivation lulo is often planted in full sun, which leads to plant stress. In order to evaluate the growth of lulo plants inoculated with mycorrhizae, under partial shade conditions, a greenhouse study was CARRIED OUT in Tunja, Colombia. The plants were inoculated with Mycobiol® (a combination of Glomus spp., Entrophospora colombiana, and Acaulospora mellea), Scutellospora heterogama alone, Acaulospora mellea alone, and Glomus spp. alone. Half of these inoculated plants were grown under a shade cloth, while the control plants were grown in full sun without mycorrhizae. Glomus spp. and S. heterogamainduced full-sun plants 55% taller than in treatments without mycorrhizae. Full-sun plants treated with S. heterogama. Mycobiol, Glomus spp., and A. mellea respectively presented 290%, 186%, 142%, and 124% more leaf area than plants without mycorrhizae. There was a 37% reduction in specific leaf weight in shaded plants with respect to mycorrhizal plants in full sun. Shaded mycorrhizal plants also had 27% lower dry matter accumulation compared to plants in full sun. Full-sun plants inoculated with S. heterogama and with Glomusspp. produced 153% and 132% more dry matter than control plants. Inoculation with mycorrhizae compensated the negative effect of shade on plant growth.
