Morphologic and physiological attributes of Brachiaria genotypes in soil with low available phosphorus and high aluminum saturation
Two Brachiaria genotypes (Brachiaria decumbens, considered as better adapted and Brachiaria ruziziensis, considered as less adapted) and 8 progenies from the cross of these two (H-7, H-40, H-28 and H-58 more adapted; H-190, H-94, H-82 and H-179 less adapted) were evaluated during 6 weeks to detect differences in shoot and root attributes when grown in an acid soil from Matazul, Meta, Colombia. Results indicated that better adapted genotypes to low P had more shoot biomass, this could be explained by a greater leaf area, more P uptake in the stem and greater root volume. The root attributes, root length, root dry weight and root P content contributed to greater adaptation to low P availability in acid soils. Six weeks o
