Arbuscular mycorrhiza and kinetic parameters of phosphorus absorption by bean plants

Autores: Silveira,Adriana Parada Dias da; Cardoso,Elke Jurandy Bran Nogueira.
The mechanisms that determine greater P absorption by mycorrhizal plants are still not completely clear, and are attributed, in part, to an increase in the number of absorption sites promoted by the hyphae, and/or to a greater affinity of the colonized hypha or root carriers to P. The effect of mycorrhizae formed by Glomus etunicatum on the kinetic parameters of P absorption by the roots and on P influx in bean plants of the IAC-Carioca cultivar was evaluated, in two distinct plant development periods: at the onset of flowering and at the pod-filling stage (35 and 50 days after sowing, respectively). A mixture of sand and silica (9:1) was utilized as substrate and irrigated with nutrient solution. The kinetics assay was performed by the method of 32P...
