Abstract
The cation exchange capacity of root (CECr) occur, mainly on the cell wall, and affect the nutrients uptake by plants. However, there is few researches evaluating the CECr in plants with nutritional deficiency. Thereby, the aim this work was (I) asses the influence of nutritional deficiency on the CECr, and (II) to research the between the nutritional status of oat and CECr. For this, the plants were cultivated during50 days with nutrient solutions with deficiency of Ca, Mg, P and Mn, control solution containing all nutrients. After the period of growing was determined the CECr, the dry matter, the nutrients content and the accumulation in shoot. The deficiency of Ca, Mg, P and Mn reduced dry matter, increased the CECr and affected the nutritional status of oat cultivated in nutritional solution. The CECr was correlate with the concentration of K and Cu in the shoot of oat. Additional keywords: apoplast; forage; nutrients acquisition; nutrients contents.
