Silício no processo infeccioso de Phakopsora pachyrhizi em folíolos de plantas de soja
[Silicon on the infection process of Phakopsora pachyrhizi on soybean leaflets]
Pesquisa Agropecuária Brasileira 47 (1), 142-145
Abstract: The objective of this work was to evaluate the effect of silicon (Si) on the infection process of Phakopsora pachyrhizi in leaflets of soybean plants grown in nutrient solution with or without Si. Observations done with light microscope and scanning electron microscope indicated that, in leaflets of plants supplied with Si, uredia were smaller and fewer in number. There were reductions of 27, 23 and 60% in the number of lesions, closed uredia and open uredia, respectively, in leaflets of plants with Si. Soybean plants supplied with Si show reduction in Asian soybean rust symptoms.
