Desenvolvimento Vegetativo e morfologia radicular de citrange carrizo afetado por ácido indolbutírico e micorrizas arbusculares

Abstract: Este estudo foi realizado na localidade de Alcanar (Tarragona, Espanha) e objetivou avaliar o efeito de cinco concentrações do ácido indolbutírico (AIB) (0,0; 0,5; 1,0; 1,5; 2,0 g/L) e da inoculação com micorrizas arbusculares (MA) (Glomus intraradices Schenck & Smith) sobre o desenvolvimento vegetativo, conteúdo foliar de P e K e morfologia radicular de plântulas de citrange Carrizo (Citrus sinensis (L.) X Poncirus trifoliata (L.) Raf.). Utilizou-se o delineamento experimental de blocos completos casualis… Show more

“…The results showed that L. camara cuttings, when inoculated with mycorrhizal fungi in the presence of IBA, had a considerable increase in their biometric characteristics, although in some cases there was no difference in comparison to the control. Studies with Prumus persica and Citrange carriz showed that the association between AMF and IBA is responsible for a large increase in vegetative development, and when analyzed separately, they do not present good results, with IBA being ineffective when not associated (Souza et al 2000, Nunes et al 2010.…”

“…Segundo Hartmann et al (1997) isso pode ser explicado, em parte, pelo fato de que as miniestacas poderiam estar em pleno desenvolvimento no qual o balanço hormonal interno se mostrava favorável ocorrendo, portanto, uma resposta negativa às aplicações do AIB. Entretanto, incremento nos conteúdos foliares de P e K em plantas de Citrange carrizo (Souza et al, 2000) e de macronutrientes (N, P, K, Ca e Mg) em pessegueiro (Nunes et al, 2010) foi notado com o aumento das concentrações da auxina (AIB).…”

“…One of the positive effects of the AMF is in function of the presence of the external mycelia, which play an important role in slow diffusion nutrient absorption, such as phosphorus and potassium (Minhoni & Auler, 2003;Souza et al, 2000;Tobar et al, 1994), increasing the nutritional content of the plants (An et al, 1993;Barea, 1991). Associated to this, the modifications caused by the AMF in the xylem structure, such as increase in the number and diameter of the metaxylem and secondary xylem cells, permitted a greater flow of nutrient absorption, such as nitrogen, phosphorus and potassium, translocated to the upper part of the plant, culminating in accelerated growth (Souza, 2000;Souza et al, 2000).…”
