Title : Effect of inoculation with Acaulospora and Glomus on growth and nutrition of Blueberry plants (Vaccinium corymbosum) with different fertilization levels

Abstract:

In recent years the demand for blueberries worldwide has been growing, due to the nutraceutical properties of the fruit that generate important benefits for human health. Colombia, due to its diversity, has a great opportunity to meet the demands of the world market. In the present study, the effect of two arbuscular mycorrhizal fungi (HFMA), of the genera Glomus (Glo) and Acaulospora (Aca) associated with blueberry plants var. Biloxi when growing on three levels of fertilization (100, 50 and 0%). The results indicate that blueberry plants inoculated with HFMA (Glo) under conditions of nutritional stress (50HFM1 +) presented an increase in dry mass (DM), plant height (AP), basal branches (RB), leaf area (AF) and root / part area ratio (R / PA), with increases in chlorophyll concentration, with statistically significant higher values with respect to treatments without inoculation with nutritional stress (0HFM- and 50HFM-). The plants inoculated with (Glo) achieved an increase in AP, while those inoculated (Aca) increased in RB, when they grew under nutritional stress in relation to the control without inoculation. The results suggest that the best association of blueberry occurs with Glomus with increased growth and nutrition (N, P, K, Ca, Mg and S).
