“…Mycorrhizal colonization of brachiaria roots started slowly and was detected only after day 102 (Table 2). Costa et al (2012) recorded colonization varying between 40 and 50% at 60 days after inoculation of U. brizantha with Rhizophagus spp. The colonization rate may have been slow in this study because of the high P availability in the compost at the beginning of pH in 0.01 mol L -1 CaCl 2 ; Ca, Mg, K and Na in Mehlich-III by ICP-OES; Available P in Mehlich-I (EMBRAPA, 2009) 2.…”

“…A colonização das raízes por micorrizas arbusculares (MA) resulta em modificações na fisiologia, bioquímica e nutrição mineral da planta hospedeira, especialmente no PubVet Maringá, v. 9, n. 9, p. 405-408, Set., 2015 favorecimento da absorção, translocação e utilização de nutrientes e água. Nos solos de baixa fertilidade natural, notadamente naqueles deficientes em fósforo, as associações com MA apresentam efeitos benéficos mais acentuados (Mosse, 1973, Noda, 2009, Costa et al, 2012. Rhodes & Gerdemann (1975) observaram que plantas colonizadas absorviam 32 P colocado até 8 cm de distância da superfície da raiz, devido as hifas externas do fungo funcionarem como extensão do sistema radicular, podendo absorver nutrientes além da zona dos pelos radiculares e da zona de depleção (1 a 2 mm) que se desenvolve ao redor das raízes.…”

“…This process is more significant in the soils of the Brazilian Cerrado with low P levels, which is a condition that stimulates the establishment of mycorrhizae (BALOTA et al, 2012). Costa et al (2012) studied the effect of arbuscular mycorrhizae on the growth and nutritional status of Brachiaria brizantha cv. Marandu and found that inoculation of mycorrhizal fungi significantly influenced dry matter yields and macronutrient absorption.…”
